A typical combat encounter is a clash between two sides, a flurry of weapon swings, feints, parries, footwork, and spellcasting. The game organizes the chaos of combat into a cycle of rounds and turns. A round represents about 6 seconds in the game world. During a round, each participant in a battle takes a turn. The order of turns is determined at the beginning of a combat encounter, when everyone rolls initiative. Once everyone has taken a turn, the fight continues to the next round if neither side has defeated the other.

Combat Step by Step

1. Determine surprise. The GM determines whether anyone involved in the combat encounter is surprised.

2. Establish positions. The GM decides where all the characters and monsters are located. Given the adventurers’ marching order or their stated positions in the room or other location, the GM figures out where the adversaries are–how far away and in what direction.

3. Roll initiative. Everyone involved in the combat encounter rolls initiative, determining the order of combatants’ turns.

4. Take turns. Each participant in the battle takes a turn in initiative order.

5. Begin the next round. When everyone involved in the combat has had a turn, the round ends. Repeat step 4 until the fighting stops.

Surprise

A band of adventurers sneaks up on a bandit camp, springing from the trees to attack them. A gelatinous cube glides down a dungeon passage, unnoticed by the adventurers until the cube engulfs one of them. In these situations, one side of the battle gains surprise over the other.

The GM determines who might be surprised. If neither side tries to be stealthy, they automatically notice each other. Otherwise, the GM compares the Dexterity (Stealth) checks of anyone hiding with the passive Wisdom (Perception) score of each creature on the opposing side. Any character or monster that doesn’t notice a threat is surprised at the start of the encounter.

If you’re surprised, you can’t move or take an action on your first turn of the combat, and you can’t take a reaction until that turn ends. A member of a group can be surprised even if the other members aren’t.

Initiative

Initiative determines the order of turns during combat. When combat starts, every participant makes a Dexterity check to determine their place in the initiative order. The GM makes one roll for an entire group of identical creatures, so each member of the group acts at the same time.

The GM ranks the combatants in order from the one with the highest Dexterity check total to the one with the lowest. This is the order (called the initiative order) in which they act during each round. The initiative order remains the same from round to round.

If a tie occurs, the GM decides the order among tied GM-controlled creatures, and the players decide the order among their tied characters. The GM can decide the order if the tie is between a monster and a player character. Optionally, the GM can have the tied characters and monsters each roll a d20 to determine the order, highest roll going first.

Your Turn

On your turn, you can move a distance up to your speed and take one action. You decide whether to move first or take your action first. Your speed–sometimes called your walking speed–is noted on your character sheet.

The most common actions you can take are described in the “Actions in Combat” section later in this chapter. Many class features and other abilities provide additional options for your action.

The “Movement and Position” section later in this chapter gives the rules for your move.

You can forgo moving, taking an action, or doing anything at all on your turn. If you can’t decide what to do on your turn, consider taking the Dodge or Ready action, as described in “Actions in Combat.”

Bonus Actions

Various class features, spells, and other abilities let you take an additional action on your turn called a bonus action. The Cunning Action feature, for example, allows a rogue to take a bonus action. You can take a bonus action only when a special ability, spell, or other feature of the game states that you can do something as a bonus action. You otherwise don’t have a bonus action to take.

You can take only one bonus action on your turn, so you must choose which bonus action to use when you have more than one available.

You choose when to take a bonus action during your turn, unless the bonus action’s timing is specified, and anything that deprives you of your ability to take actions also prevents you from taking a bonus action.

Other Activity on Your Turn

Your turn can include a variety of flourishes that require neither your action nor your move.

You can communicate however you are able, through brief utterances and gestures, as you take your turn.

You can also interact with one object or feature of the environment for free, during either your move or your action. For example, you could open a door during your move as you stride toward a foe, or you could draw your weapon as part of the same action you use to attack.

If you want to interact with a second object, you need to use your action. Some magic items and other special objects always require an action to use, as stated in their descriptions.

The GM might require you to use an action for any of these activities when it needs special care or when it presents an unusual obstacle. For instance, the GM could reasonably expect you to use an action to open a stuck door or turn a crank to lower a drawbridge.

Reactions

Certain special abilities, spells, and situations allow you to take a special action called a reaction. A reaction is an instant response to a trigger of some kind, which can occur on your turn or on someone else’s. The opportunity attack, described later in this chapter, is the most common type of reaction.

When you take a reaction, you can’t take another one until the start of your next turn. If the reaction interrupts another creature’s turn, that creature can continue its turn right after the reaction.

When adventurers pursue sahuagin back to their undersea homes, fight off sharks in an ancient shipwreck, or find themselves in a flooded dungeon room, they must fight in a challenging environment. Underwater the following rules apply.

When making a melee weapon attack, a creature that doesn’t have a swimming speed (either natural or granted by magic) has disadvantage on the attack roll unless the weapon is a dagger, javelin, shortsword, spear, or trident.

A ranged weapon attack automatically misses a target beyond the weapon’s normal range. Even against a target within normal range, the attack roll has disadvantage unless the weapon is a crossbow, a net, or a weapon that is thrown like a javelin (including a spear, trident, or dart).

Creatures and objects that are fully immersed in water have resistance to fire damage.

A typical creature in the game world has an alignment, which broadly describes its moral and personal attitudes. Alignment is a combination of two factors: one identifies morality (good, evil, or neutral), and the other describes attitudes toward society and order (lawful, chaotic, or neutral). Thus, nine distinct alignments define the possible combinations.

These brief summaries of the nine alignments describe the typical behavior of a creature with that alignment. Individuals might vary significantly from that typical behavior, and few people are perfectly and consistently faithful to the precepts of their alignment.

Lawful good (LG) creatures can be counted on to do the right thing as expected by society. Gold dragons, paladins, and most dwarves are lawful good.

Neutral good (NG) folk do the best they can to help others according to their needs. Many celestials, some cloud giants, and most gnomes are neutral good.

Chaotic good (CG) creatures act as their conscience directs, with little regard for what others expect. Copper dragons, many elves, and unicorns are chaotic good.

Lawful neutral (LN) individuals act in accordance with law, tradition, or personal codes. Many monks and some wizards are lawful neutral.

Neutral (N) is the alignment of those who prefer to steer clear of moral questions and don’t take sides, doing what seems best at the time. Lizardfolk, most druids, and many humans are neutral.

Chaotic neutral (CN) creatures follow their whims, holding their personal freedom above all else. Many barbarians and rogues, and some bards, are chaotic neutral.

Lawful evil (LE) creatures methodically take what they want, within the limits of a code of tradition, loyalty, or order. Devils, blue dragons, and hobgoblins are lawful evil.

Neutral evil (NE) is the alignment of those who do whatever they can get away with, without compassion or qualms. Many drow, some cloud giants, and goblins are neutral evil.

Chaotic evil (CE) creatures act with arbitrary violence, spurred by their greed, hatred, or bloodlust. Demons, red dragons, and orcs are chaotic evil.

Alignment in the Multiverse

For many thinking creatures, alignment is a moral choice. Humans, dwarves, elves, and other humanoid races can choose whether to follow the paths of good or evil, law or chaos. According to myth, the good-aligned gods who created these races gave them free will to choose their moral paths, knowing that good without free will is slavery.

The evil deities who created other races, though, made those races to serve them. Those races have strong inborn tendencies that match the nature of their gods. Most orcs share the violent, savage nature of the orc gods, and are thus inclined toward evil. Even if an orc chooses a good alignment, it struggles against its innate tendencies for its entire life. (Even half-orcs feel the lingering pull of the orc god’s influence.)

Alignment is an essential part of the nature of celestials and fiends. A devil does not choose to be lawful evil, and it doesn’t tend toward lawful evil, but rather it is lawful evil in its essence. If it somehow ceased to be lawful evil, it would cease to be a devil.

Most creatures that lack the capacity for rational thought do not have alignments – they are unaligned. Such a creature is incapable of making a moral or ethical choice and acts according to its bestial nature. Sharks are savage predators, for example, but they are not evil; they have no alignment.

Every story has a beginning. Your character’s background reveals where you came from, how you became an adventurer, and your place in the world. Your fighter might have been a courageous knight or a grizzled soldier. Your wizard could have been a sage or an artisan. Your rogue might have gotten by as a guild thief or commanded audiences as a jester.

Choosing a background provides you with important story cues about your character’s identity. The most important question to ask about your background is what changed? Why did you stop doing whatever your background describes and start adventuring? Where did you get the money to purchase your starting gear, or, if you come from a wealthy background, why don’t you have more money? How did you learn the skills of your class? What sets you apart from ordinary people who share your background?

The sample backgrounds in this chapter provide both concrete benefits (features, proficiencies, and languages) and roleplaying suggestions.

Proficiencies

Each background gives a character proficiency in two skills.

In addition, most backgrounds give a character proficiency with one or more tools.

If a character would gain the same proficiency from two different sources, he or she can choose a different proficiency of the same kind (skill or tool) instead.

Languages

Some backgrounds also allow characters to learn additional languages beyond those given by race.

Equipment

Each background provides a package of starting equipment. If you use the optional rule to spend coin on gear, you do not receive the starting equipment from your background.

Suggested Characteristics

A background contains suggested personal characteristics based on your background. You can pick characteristics, roll dice to determine them randomly, or use the suggestions as inspiration for characteristics of your own creation. Customizing a Background You might want to tweak some of the features of a background so it better fits your character or the campaign setting. To customize a background, you can replace one feature with any other one, choose any two skills, and choose a total of two tool proficiencies or languages from the sample backgrounds. You can either use the equipment package from your background or spend coin on gear as described in the equipment section. (If you spend coin, you can’t also take the equipment package suggested for your class.) Finally, choose two personality traits, one ideal, one bond, and one flaw. If you can’t find a feature that matches your desired background, work with your GM to create one.

Acolyte

You have spent your life in the service of a temple to a specific god or pantheon of gods. You act as an intermediary between the realm of the holy and the mortal world, performing sacred rites and offering sacrifices in order to conduct worshipers into the presence of the divine. You are not necessarily a cleric – performing sacred rites is not the same thing as channeling divine power.

Choose a god, a pantheon of gods, or some other quasi-divine being from among those listed in “Fantasy–Historical Pantheons” or those specified by your GM, and work with your GM to detail the nature of your religious service. Were you a lesser functionary in a temple, raised from childhood to assist the priests in the sacred rites? Or were you a high priest who suddenly experienced a call to serve your god in a different way? Perhaps you were the leader of a small cult outside of any established temple structure, or even an occult group that served a fiendish master that you now deny.

Skill Proficiencies: Insight, Religion
Languages: Two of your choice
Equipment: A holy symbol (a gift to you when you entered the priesthood), a prayer book or prayer wheel, 5 sticks of incense, vestments, a set of common clothes, and a pouch containing 15 gp

Feature: Shelter of the Faithful

As an acolyte, you command the respect of those who share your faith, and you can perform the religious ceremonies of your deity. You and your adventuring companions can expect to receive free healing and care at a temple, shrine, or other established presence of your faith, though you must provide any material components needed for spells. Those who share your religion will support you (but only you) at a modest lifestyle.

You might also have ties to a specific temple dedicated to your chosen deity or pantheon, and you have a residence there. This could be the temple where you used to serve, if you remain on good terms with it, or a temple where you have found a new home. While near your temple, you can call upon the priests for assistance, provided the assistance you ask for is not hazardous and you remain in good standing with your temple.

Suggested Characteristics

Acolytes are shaped by their experience in temples or other religious communities. Their study of the history and tenets of their faith and their relationships to temples, shrines, or hierarchies affect their mannerisms and ideals. Their flaws might be some hidden hypocrisy or heretical idea, or an ideal or bond taken to an extreme.

The Celtic, Egyptian, Greek, and Norse pantheons are fantasy interpretations of historical religions from our world’s ancient times. They include deities that are most appropriate for use in a game, divorced from their historical context in the real world and united into pantheons that serve the needs of the game.

The Celtic Pantheon

It’s said that something wild lurks in the heart of every soul, a space that thrills to the sound of geese calling at night, to the whispering wind through the pines, to the unexpected red of mistletoe on an oak–and it is in this space that the Celtic gods dwell. They sprang from the brook and stream, their might heightened by the strength of the oak and the beauty of the woodlands and open moor. When the first forester dared put a name to the face seen in the bole of a tree or the voice babbling in a brook, these gods forced themselves into being.

The Celtic gods are as often served by druids as by clerics, for they are closely aligned with the forces of nature that druids revere.

The Greek Pantheon

The gods of Olympus make themselves known with the gentle lap of waves against the shores and the crash of the thunder among the cloud-enshrouded peaks. The thick boar-infested woods and the sere, olive-covered hillsides hold evidence of their passing. Every aspect of nature echoes with their presence, and they’ve made a place for themselves inside the human heart, too.

The Egyptian Pantheon

These gods are a young dynasty of an ancient divine family, heirs to the rulership of the cosmos and the maintenance of the divine principle of Ma’at–the fundamental order of truth, justice, law, and order that puts gods, mortal pharaohs, and ordinary men and women in their logical and rightful place in the universe.

The Egyptian pantheon is unusual in having three gods responsible for death, each with different alignments. Anubis is the lawful neutral god of the afterlife, who judges the souls of the dead. Set is a chaotic evil god of murder, perhaps best known for killing his brother Osiris. And Nephthys is a chaotic good goddess of mourning.

The Norse Pantheon

Where the land plummets from the snowy hills into the icy fjords below, where the longboats draw up on to the beach, where the glaciers flow forward and retreat with every fall and spring–this is the land of the Vikings, the home of the Norse pantheon. It’s a brutal clime, and one that calls for brutal living. The warriors of the land have had to adapt to the harsh conditions in order to survive, but they haven’t been too twisted by the needs of their environment. Given the necessity of raiding for food and wealth, it’s surprising the mortals turned out as well as they did. Their powers reflect the need these warriors had for strong leadership and decisive action. Thus, they see their deities in every bend of a river, hear them in the crash of the thunder and the booming of the glaciers, and smell them in the smoke of a burning longhouse.

The Norse pantheon includes two main families, the Aesir (deities of war and destiny) and the Vanir (gods of fertility and prosperity). Once enemies, these two families are now closely allied against their common enemies, the giants (including the gods Surtur and Thrym).

Celtic Deities

Greek Deities

Egyptian Deities

Norse Deities

Your race indicates the languages your character can speak by default, and your background might give you access to one or more additional languages of your choice. Note these languages on your character sheet.

Choose your languages from the Standard Languages table, or choose one that is common in your campaign. With your GM’s permission, you can instead choose a language from the Exotic Languages table or a secret language, such as thieves’ cant or the tongue of druids.

Some of these languages are actually families of languages with many dialects. For example, the Primordial language includes the Auran, Aquan, Ignan, and Terran dialects, one for each of the four elemental planes. Creatures that speak different dialects of the same language can communicate with one another.

Standard Languages

Exotic Languages

Between trips to dungeons and battles against ancient evils, adventurers need time to rest, recuperate, and prepare for their next adventure. Many adventurers also use this time to perform other tasks, such as crafting arms and armor, performing research, or spending their hard-earned gold.

In some cases, the passage of time is something that occurs with little fanfare or description. When starting a new adventure, the GM might simply declare that a certain amount of time has passed and allow you to describe in general terms what your character has been doing. At other times, the GM might want to keep track of just how much time is passing as events beyond your perception stay in motion.

Lifestyle Expenses

Between adventures, you choose a particular quality of life and pay the cost of maintaining that lifestyle.

Living a particular lifestyle doesn’t have a huge effect on your character, but your lifestyle can affect the way other individuals and groups react to you. For example, when you lead an aristocratic lifestyle, it might be easier for you to influence the nobles of the city than if you live in poverty.

Downtime Activities

Between adventures, the GM might ask you what your character is doing during his or her downtime. Periods of downtime can vary in duration, but each downtime activity requires a certain number of days to complete before you gain any benefit, and at least 8 hours of each day must be spent on the downtime activity for the day to count. The days do not need to be consecutive. If you have more than the minimum amount of days to spend, you can keep doing the same thing for a longer period of time, or switch to a new downtime activity.

Downtime activities other than the ones presented below are possible. If you want your character to spend his or her downtime performing an activity not covered here, discuss it with your GM.

Crafting

You can craft nonmagical objects, including adventuring equipment and works of art. You must be proficient with tools related to the object you are trying to create (typically artisan’s tools). You might also need access to special materials or locations necessary to create it. For example, someone proficient with smith’s tools needs a forge in order to craft a sword or suit of armor.

For every day of downtime you spend crafting, you can craft one or more items with a total market value not exceeding 5 gp, and you must expend raw materials worth half the total market value. If something you want to craft has a market value greater than 5 gp, you make progress every day in 5-gp increments until you reach the market value of the item. For example, a suit of plate armor (market value 1,500 gp) takes 300 days to craft by yourself.

Multiple characters can combine their efforts toward the crafting of a single item, provided that the characters all have proficiency with the requisite tools and are working together in the same place. Each character contributes 5 gp worth of effort for every day spent helping to craft the item. For example, three characters with the requisite tool proficiency and the proper facilities can craft a suit of plate armor in 100 days, at a total cost of 750 gp.

While crafting, you can maintain a modest lifestyle without having to pay 1 gp per day, or a comfortable lifestyle at half the normal cost.

Practicing a Profession

You can work between adventures, allowing you to maintain a modest lifestyle without having to pay 1 gp per day. This benefit lasts as long you continue to practice your profession.

If you are a member of an organization that can provide gainful employment, such as a temple or a thieves’ guild, you earn enough to support a comfortable lifestyle instead.

If you have proficiency in the Performance skill and put your performance skill to use during your downtime, you earn enough to support a wealthy lifestyle instead.

Recuperating

You can use downtime between adventures to recover from a debilitating injury, disease, or poison.

After three days of downtime spent recuperating, you can make a DC 15 Constitution saving throw. On a successful save, you can choose one of the following results:

• End one effect on you that prevents you from regaining hit points.
• For the next 24 hours, gain advantage on saving throws against one disease or poison currently affecting you.

Researching

The time between adventures is a great chance to perform research, gaining insight into mysteries that have unfurled over the course of the campaign. Research can include poring over dusty tomes and crumbling scrolls in a library or buying drinks for the locals to pry rumors and gossip from their lips.

When you begin your research, the GM determines whether the information is available, how many days of downtime it will take to find it, and whether there are any restrictions on your research (such as needing to seek out a specific individual, tome, or location). The GM might also require you to make one or more ability checks, such as an Intelligence (Investigation) check to find clues pointing toward the information you seek, or a Charisma (Persuasion) check to secure someone’s aid. Once those conditions are met, you learn the information if it is available.

For each day of research, you must spend 1 gp to cover your expenses. This cost is in addition to your normal lifestyle expenses.

Training

You can spend time between adventures learning a new language or training with a set of tools. Your GM might allow additional training options.

First, you must find an instructor willing to teach you. The GM determines how long it takes, and whether one or more ability checks are required.

The training lasts for 250 days and costs 1 gp per day. After you spend the requisite amount of time and money, you learn the new language or gain proficiency with the new tool.

Swimming across a rushing river, sneaking down a dungeon corridor, scaling a treacherous mountain slope–all sorts of movement play a key role in fantasy gaming adventures.

The GM can summarize the adventurers’ movement without calculating exact distances or travel times: “You travel through the forest and find the dungeon entrance late in the evening of the third day.” Even in a dungeon, particularly a large dungeon or a cave network, the GM can summarize movement between encounters: “After killing the guardian at the entrance to the ancient dwarven stronghold, you consult your map, which leads you through miles of echoing corridors to a chasm bridged by a narrow stone arch.”

Sometimes it’s important, though, to know how long it takes to get from one spot to another, whether the answer is in days, hours, or minutes. The rules for determining travel time depend on two factors: the speed and travel pace of the creatures moving and the terrain they’re moving over.

Speed

Every character and monster has a speed, which is the distance in feet that the character or monster can walk in 1 round. This number assumes short bursts of energetic movement in the midst of a life-threatening situation. The following rules determine how far a character or monster can move in a minute, an hour, or a day.

Travel Pace

While traveling, a group of adventurers can move at a normal, fast, or slow pace, as shown on the Travel Pace table. The table states how far the party can move in a period of time and whether the pace has any effect. A fast pace makes characters less perceptive, while a slow pace makes it possible to sneak around and to search an area more carefully.

Forced March. The Travel Pace table assumes that characters travel for 8 hours in day. They can push on beyond that limit, at the risk of exhaustion.

For each additional hour of travel beyond 8 hours, the characters cover the distance shown in the Hour column for their pace, and each character must make a Constitution saving throw at the end of the hour. The DC is 10 + 1 for each hour past 8 hours. On a failed saving throw, a character suffers one level of exhaustion.

Mounts and Vehicles. For short spans of time (up to an hour), many animals move much faster than humanoids. A mounted character can ride at a gallop for about an hour, covering twice the usual distance for a fast pace. If fresh mounts are available every 8 to 10 miles, characters can cover larger distances at this pace, but this is very rare except in densely populated areas.

Characters in wagons, carriages, or other land vehicles choose a pace as normal. Characters in a waterborne vessel are limited to the speed of the vessel, and they don’t suffer penalties for a fast pace or gain benefits from a slow pace. Depending on the vessel and the size of the crew, ships might be able to travel for up to 24 hours per day.

Certain special mounts, such as a pegasus or griffon, or special vehicles, such as a carpet of flying, allow you to travel more swiftly.

Difficult Terrain

The travel speeds given in the Travel Pace table assume relatively simple terrain: roads, open plains, or clear dungeon corridors. But adventurers often face dense forests, deep swamps, rubble-filled ruins, steep mountains, and ice-covered ground–all considered difficult terrain.

You move at half speed in difficult terrain–moving 1 foot in difficult terrain costs 2 feet of speed–so you can cover only half the normal distance in a minute, an hour, or a day.

Special Types of Movement

Movement through dangerous dungeons or wilderness areas often involves more than simply walking. Adventurers might have to climb, crawl, swim, or jump to get where they need to go.

Climbing, Swimming, and Crawling

While climbing or swimming, each foot of movement costs 1 extra foot (2 extra feet in difficult terrain), unless a creature has a climbing or swimming speed. At the GM’s option, climbing a slippery vertical surface or one with few handholds requires a successful Strength (Athletics) check. Similarly, gaining any distance in rough water might require a successful Strength (Athletics) check.

Jumping

Your Strength determines how far you can jump.

Long Jump. When you make a long jump, you cover a number of feet up to your Strength score if you move at least 10 feet on foot immediately before the jump. When you make a standing long jump, you can leap only half that distance. Either way, each foot you clear on the jump costs a foot of movement.

This rule assumes that the height of your jump doesn’t matter, such as a jump across a stream or chasm. At your GM’s option, you must succeed on a DC 10 Strength (Athletics) check to clear a low obstacle (no taller than a quarter of the jump’s distance), such as a hedge or low wall. Otherwise, you hit it.

When you land in difficult terrain, you must succeed on a DC 10 Dexterity (Acrobatics) check to land on your feet. Otherwise, you land prone.

High Jump. When you make a high jump, you leap into the air a number of feet equal to 3 + your Strength modifier if you move at least 10 feet on foot immediately before the jump. When you make a standing high jump, you can jump only half that distance. Either way, each foot you clear on the jump costs a foot of movement. In some circumstances, your GM might allow you to make a Strength (Athletics) check to jump higher than you normally can.

You can extend your arms half your height above yourself during the jump. Thus, you can reach above you a distance equal to the height of the jump plus 1 1/2 times your height.

The cosmos teems with a multitude of worlds as well as myriad alternate dimensions of reality, called the planes of existence. It encompasses every world where GMs run their adventures, all within the relatively mundane realm of the Material Plane. Beyond that plane are domains of raw elemental matter and energy, realms of pure thought and ethos, the homes of demons and angels, and the dominions of the gods.

Many spells and magic items can draw energy from these planes, summon the creatures that dwell there, communicate with their denizens, and allow adventurers to travel there. As your character achieves greater power and higher levels, you might walk on streets made of solid fire or test your mettle on a battlefield where the fallen are resurrected with each dawn.

The Material Plane

The Material Plane is the nexus where the philosophical and elemental forces that define the other planes collide in the jumbled existence of mortal life and mundane matter. All fantasy gaming worlds exist within the Material Plane, making it the starting point for most campaigns and adventures. The rest of the multiverse is defined in relation to the Material Plane.

The worlds of the Material Plane are infinitely diverse, for they reflect the creative imagination of the GMs who set their games there, as well as the players whose heroes adventure there. They include magic-wasted desert planets and island-dotted water worlds, worlds where magic combines with advanced technology and others trapped in an endless Stone Age, worlds where the gods walk and places they have abandoned.

Beyond the Material

Beyond the Material Plane, the various planes of existence are realms of myth and mystery. They’re not simply other worlds, but different qualities of being, formed and governed by spiritual and elemental principles abstracted from the ordinary world.

Planar Travel

When adventurers travel into other planes of existence, they are undertaking a legendary journey across the thresholds of existence to a mythic destination where they strive to complete their quest. Such a journey is the stuff of legend. Braving the realms of the dead, seeking out the celestial servants of a deity, or bargaining with an efreeti in its home city will be the subject of song and story for years to come.

Travel to the planes beyond the Material Plane can be accomplished in two ways: by casting a spell or by using a planar portal.

Spells. A number of spells allow direct or indirect access to other planes of existence. Plane shift and gate can transport adventurers directly to any other plane of existence, with different degrees of precision. Etherealness allows adventurers to enter the Ethereal Plane and travel from there to any of the planes it touches–such as the Elemental Planes. And the astral projection spell lets adventurers project themselves into the Astral Plane and travel to the Outer Planes.

Portals. A portal is a general term for a stationary interplanar connection that links a specific location on one plane to a specific location on another. Some portals are like doorways, a clear window, or a fog-shrouded passage, and simply stepping through it effects the interplanar travel. Others are locations– circles of standing stones, soaring towers, sailing ships, or even whole towns–that exist in multiple planes at once or flicker from one plane to another in turn. Some are vortices, typically joining an Elemental Plane with a very similar location on the Material Plane, such as the heart of a volcano (leading to the Plane of Fire) or the depths of the ocean (to the Plane of Water).

Transitive Planes

The Ethereal Plane and the Astral Plane are called the Transitive Planes. They are mostly featureless realms that serve primarily as ways to travel from one plane to another. Spells such as etherealness and astral projection allow characters to enter these planes and traverse them to reach the planes beyond.

The Ethereal Plane is a misty, fog-bound dimension that is sometimes described as a great ocean. Its shores, called the Border Ethereal, overlap the Material Plane and the Inner Planes, so that every location on those planes has a corresponding location on the Ethereal Plane. Certain creatures can see into the Border Ethereal, and the see invisibility and true seeing spell grant that ability. Some magical effects also extend from the Material Plane into the Border Ethereal, particularly effects that use force energy such as forcecage and wall of force. The depths of the plane, the Deep Ethereal, are a region of swirling mists and colorful fogs.

The Astral Plane is the realm of thought and dream, where visitors travel as disembodied souls to reach the planes of the divine and demonic. It is a great, silvery sea, the same above and below, with swirling wisps of white and gray streaking among motes of light resembling distant stars. Erratic whirlpools of color flicker in midair like spinning coins. Occasional bits of solid matter can be found here, but most of the Astral Plane is an endless, open domain.

Inner Planes

The Inner Planes surround and enfold the Material Plane and its echoes, providing the raw elemental substance from which all the worlds were made. The four Elemental Planes–Air, Earth, Fire, and Water–form a ring around the Material Plane, suspended within the churning Elemental Chaos.

At their innermost edges, where they are closest to the Material Plane (in a conceptual if not a literal geographical sense), the four Elemental Planes resemble a world in the Material Plane. The four elements mingle together as they do in the Material Plane, forming land, sea, and sky. Farther from the Material Plane, though, the Elemental Planes are both alien and hostile. Here, the elements exist in their purest form–great expanses of solid earth, blazing fire, crystal-clear water, and unsullied air. These regions are little-known, so when discussing the Plane of Fire, for example, a speaker usually means just the border region. At the farthest extents of the Inner Planes, the pure elements dissolve and bleed together into an unending tumult of clashing energies and colliding substance, the Elemental Chaos.

Outer Planes

If the Inner Planes are the raw matter and energy that makes up the multiverse, the Outer Planes are the direction, thought and purpose for such construction. Accordingly, many sages refer to the Outer Planes as divine planes, spiritual planes, or godly planes, for the Outer Planes are best known as the homes of deities.

When discussing anything to do with deities, the language used must be highly metaphorical. Their actual homes are not literally “places” at all, but exemplify the idea that the Outer Planes are realms of thought and spirit. As with the Elemental Planes, one can imagine the perceptible part of the Outer Planes as a sort of border region, while extensive spiritual regions lie beyond ordinary sensory experience.

Even in those perceptible regions, appearances can be deceptive. Initially, many of the Outer Planes appear hospitable and familiar to natives of the Material Plane. But the landscape can change at the whims of the powerful forces that live on the Outer Planes. The desires of the mighty forces that dwell on these planes can remake them completely, effectively erasing and rebuilding existence itself to better fulfill their own needs.

Distance is a virtually meaningless concept on the Outer Planes. The perceptible regions of the planes often seem quite small, but they can also stretch on to what seems like infinity. It might be possible to take a guided tour of the Nine Hells, from the first layer to the ninth, in a single day–if the powers of the Hells desire it. Or it could take weeks for travelers to make a grueling trek across a single layer.

The most well-known Outer Planes are a group of sixteen planes that correspond to the eight alignments (excluding neutrality) and the shades of distinction between them.

Outer Planes

The planes with some element of good in their nature are called the Upper Planes. Celestial creatures such as angels and pegasi dwell in the Upper Planes. Planes with some element of evil are the Lower Planes. Fiends such as demons and devils dwell in the Lower Planes. A plane’s alignment is its essence, and a character whose alignment doesn’t match the plane’s experiences a profound sense of dissonance there. When a good creature visits Elysium, for example (a neutral good Upper Plane), it feels in tune with the plane, but an evil creature feels out of tune and more than a little uncomfortable.

Demiplanes

Demiplanes are small extradimensional spaces with their own unique rules. They are pieces of reality that don’t seem to fit anywhere else. Demiplanes come into being by a variety of means. Some are created by spells, such as demiplane, or generated at the desire of a powerful deity or other force. They may exist naturally, as a fold of existing reality that has been pinched off from the rest of the multiverse, or as a baby universe growing in power. A given demiplane can be entered through a single point where it touches another plane. Theoretically, a plane shift spell can also carry travelers to a demiplane, but the proper frequency required for the tuning fork is extremely hard to acquire. The gate spell is more reliable, assuming the caster knows of the demiplane.

Heroic though they might be, adventurers can’t spend every hour of the day in the thick of exploration, social interaction, and combat. They need rest–time to sleep and eat, tend their wounds, refresh their minds and spirits for spellcasting, and brace themselves for further adventure.

Adventurers can take short rests in the midst of an adventuring day and a long rest to end the day.

Short Rest

A short rest is a period of downtime, at least 1 hour long, during which a character does nothing more strenuous than eating, drinking, reading, and tending to wounds.

A character can spend one or more Hit Dice at the end of a short rest, up to the character’s maximum number of Hit Dice, which is equal to the character’s level. For each Hit Die spent in this way, the player rolls the die and adds the character’s Constitution modifier to it. The character regains hit points equal to the total. The player can decide to spend an additional Hit Die after each roll. A character regains some spent Hit Dice upon finishing a long rest, as explained below.

Long Rest

A long rest is a period of extended downtime, at least 8 hours long, during which a character sleeps or performs light activity: reading, talking, eating, or standing watch for no more than 2 hours. If the rest is interrupted by a period of strenuous activity–at least 1 hour of walking, fighting, casting spells, or similar adventuring activity–the characters must begin the rest again to gain any benefit from it.

At the end of a long rest, a character regains all lost hit points. The character also regains spent Hit Dice, up to a number of dice equal to half of the character’s total number of them (minimum of one die). For example, if a character has eight Hit Dice, he or she can regain four spent Hit Dice upon finishing a long rest.

A character can’t benefit from more than one long rest in a 24-hour period, and a character must have at least 1 hit point at the start of the rest to gain its benefits.
