Wondrous item, uncommon (requires attunement)

While wearing this necklace, you can breathe normally in any environment, and you have advantage on saving throws made against harmful gases and vapors (such as cloudkill and stinking cloud effects, inhaled poisons, and the breath weapons of some dragons).

Wondrous item, rare

This necklace has 1d6 + 3 beads hanging from it. You can use an action to detach a bead and throw it up to 60 feet away. When it reaches the end of its trajectory, the bead detonates as a 3rd-level fireball spell (save DC 15).

You can hurl multiple beads, or even the whole necklace, as one action. When you do so, increase the level of the fireball by 1 for each bead beyond the first.

Armor (medium or heavy, but not hide), uncommon

Mithral is a light, flexible metal. A mithral chain shirt or breastplate can be worn under normal clothes. If the armor normally imposes disadvantage on Dexterity (Stealth) checks or has a Strength requirement, the mithral version of the armor doesn’t.

Wondrous item, rare (requires attunement by a cleric, druid, or paladin)

This necklace has 1d4 + 2 magic beads made from aquamarine, black pearl, or topaz. It also has many nonmagical beads made from stones such as amber, bloodstone, citrine, coral, jade, pearl, or quartz. If a magic bead is removed from the necklace, that bead loses its magic.

Six types of magic beads exist. The GM decides the type of each bead on the necklace or determines it randomly. A necklace can have more than one bead of the same type. To use one, you must be wearing the necklace. Each bead contains a spell that you can cast from it as a bonus action (using your spell save DC if a save is necessary). Once a magic bead’s spell is cast, that bead can’t be used again until the next dawn.

Weapon (any sword), very rare (requires attunement)

You gain a +2 bonus to attack and damage rolls made with this magic weapon.

The sword has 1d8 + 1 charges. If you score a critical hit against a creature that has fewer than 100 hit points, it must succeed on a DC 15 Constitution saving throw or be slain instantly as the sword tears its life force from its body (a construct or an undead is immune). The sword loses 1 charge if the creature is slain. When the sword has no charges remaining, it loses this property.

Wondrous item, uncommon (requires attunement by a spellcaster)

While this pearl is on your person, you can use an action to speak its command word and regain one expended spell slot. If the expended slot was of 4th level or higher, the new slot is 3rd level. Once you use the pearl, it can’t be used again until the next dawn.

Potion, uncommon

This sticky black unguent is thick and heavy in the container, but it flows quickly when poured. The oil can cover a Medium or smaller creature, along with the equipment it’s wearing and carrying (one additional vial is required for each size category above Medium). Applying the oil takes 10 minutes. The affected creature then gains the effect of a freedom of movement spell for 8 hours.

Alternatively, the oil can be poured on the ground as an action, where it covers a 10-foot square, duplicating the effect of the grease spell in that area for 8 hours.

Potion, very rare

This clear, gelatinous oil sparkles with tiny, ultrathin silver shards. The oil can coat one slashing or piercing weapon or up to 5 pieces of slashing or piercing ammunition. Applying the oil takes 1 minute. For 1 hour, the coated item is magical and has a +3 bonus to attack and damage rolls.

Weapon (longbow), very rare (requires attunement)

When you nock an arrow on this bow, it whispers in Elvish, “Swift defeat to my enemies.” When you use this weapon to make a ranged attack, you can, as a command phrase, say, “Swift death to you who have wronged me.” The target of your attack becomes your sworn enemy until it dies or until dawn seven days later. You can have only one such sworn enemy at a time. When your sworn enemy dies, you can choose a new one after the next dawn.

When you make a ranged attack roll with this weapon against your sworn enemy, you have advantage on the roll. In addition, your target gains no benefit from cover, other than total cover, and you suffer no disadvantage due to long range. If the attack hits, your sworn enemy takes an extra 3d6 piercing damage.

While your sworn enemy lives, you have disadvantage on attack rolls with all other weapons.

Potion, rare

Beads of this cloudy gray oil form on the outside of its container and quickly evaporate. The oil can cover a Medium or smaller creature, along with the equipment it’s wearing and carrying (one additional vial is required for each size category above Medium). Applying the oil takes 10 minutes. The affected creature then gains the effect of the etherealness spell for 1 hour.
