Weapon (any sword that deals slashing damage), very rare (requires attunement)

When you attack an object with this magic sword and hit, maximize your weapon damage dice against the target.

When you attack a creature with this weapon and roll a 20 on the attack roll, that target takes an extra 4d6 slashing damage. Then roll another d20. If you roll a 20, you lop off one of the target’s limbs, with the effect of such loss determined by the GM. If the creature has no limb to sever, you lop off a portion of its body instead.

In addition, you can speak the sword’s command word to cause the blade to shed bright light in a 10* foot radius and dim light for an additional 10 feet. Speaking the command word again or sheathing the sword puts out the light.

Wondrous item, legendary

This viscous, milky-white substance can form a permanent adhesive bond between any two objects. It must be stored in a jar or flask that has been coated inside with oil of slipperiness. When found, a container contains 1d6 + 1 ounces.

One ounce of the glue can cover a 1-foot square surface. The glue takes 1 minute to set. Once it has done so, the bond it creates can be broken only by the application of universal solvent or oil of etherealness, or with a wish spell.

Staff, very rare (requires attunement by a druid, sorcerer, warlock, or wizard)

You have resistance to fire damage while you hold this staff.

The staff has 10 charges. While holding it, you can use an action to expend 1 or more of its charges to cast one of the following spells from it, using your spell save DC: burning hands (1 charge), fireball (3 charges), or wall of fire (4 charges).

The staff regains 1d6 + 4 expended charges daily at dawn. If you expend the last charge, roll a d20. On a 1, the staff blackens, crumbles into cinders, and is destroyed.

Armor (shield), very rare (requires attunement)

While holding this shield, you have advantage on saving throws against spells and other magical effects, and spell attacks have disadvantage against you.

Wondrous item, uncommon (requires attunement)

While you wear these light shoes, you can move up, down, and across vertical surfaces and upside down along ceilings, while leaving your hands free. You have a climbing speed equal to your walking speed. However, the slippers don’t allow you to move this way on a slippery surface, such as one covered by ice or oil.

Staff, very rare (requires attunement by a sorcerer, warlock, or wizard)

This staff can be wielded as a magic quarterstaff that grants a +2 bonus to attack and damage rolls made with it. While holding it, you gain a +2 bonus to Armor Class, saving throws, and spell attack rolls.

The staff has 20 charges for the following properties. The staff regains 2d8 + 4 expended charges daily at dawn. If you expend the last charge, roll a d20. On a 1, the staff retains its +2 bonus to attack and damage rolls but loses all other properties. On a 20, the staff regains 1d8 + 2 charges.
Power Strike. When you hit with a melee attack using the staff, you can expend 1 charge to deal an extra 1d6 force damage to the target.
Spells. While holding this staff, you can use an action to expend 1 or more of its charges to cast one of the following spells from it, using your spell save DC and spell attack bonus: cone of cold (5 charges), fireball (5th-level version, 5 charges), globe of invulnerability (6 charges), hold monster (5 charges), levitate (2 charges), lightning bolt (5th-level version, 5 charges), magic missile (1 charge), ray of enfeeblement (1 charge), or wall of force (5 charges).
Retributive Strike. You can use an action to break the staff over your knee or against a solid surface, performing a retributive strike. The staff is destroyed and releases its remaining magic in an explosion that expands to fill a 30-foot-radius sphere centered on it.

You have a 50 percent chance to instantly travel to a random plane of existence, avoiding the explosion. If you fail to avoid the effect, you take force damage equal to 16 × the number of charges in the staff. Every other creature in the area must make a DC 17 Dexterity saving throw. On a failed save, a creature takes an amount of damage based on how far away it is from the point of origin, as shown in the following table. On a successful save, a creature takes half as much damage.

Staff, very rare (requires attunement)

This staff can be wielded as a magic quarterstaff that grants a +3 bonus to attack and damage rolls made with it.

The staff has 10 charges. When you hit with a melee attack using it, you can expend up to 3 of its charges. For each charge you expend, the target takes an extra 1d6 force damage. The staff regains 1d6 + 4 expended charges daily at dawn. If you expend the last charge, roll a d20. On a 1, the staff becomes a nonmagical quarterstaff.

Staff, rare (requires attunement by a bard, cleric, druid, sorcerer, warlock, or wizard)

This staff has 10 charges and regains 1d6 + 4 expended charges daily at dawn. If you expend the last charge, roll a d20. On a 1, a swarm of insects consumes and destroys the staff, then disperses.
Spells. While holding the staff, you can use an action to expend some of its charges to cast one of the following spells from it, using your spell save DC: giant insect (4 charges) or insect plague (5 charges).
Insect Cloud. While holding the staff, you can use an action and expend 1 charge to cause a swarm of harmless flying insects to spread out in a 30-foot radius from you. The insects remain for 10 minutes, making the area heavily obscured for creatures other than you. The swarm moves with you, remaining centered on you. A wind of at least 10 miles per hour disperses the swarm and ends the effect.

Scroll, varies

A spell scroll bears the words of a single spell, written in a mystical cipher. If the spell is on your class’s spell list, you can use an action to read the scroll and cast its spell without having to provide any of the spell’s components. Otherwise, the scroll is unintelligible.

If the spell is on your class’s spell list but of a higher level than you can normally cast, you must make an ability check using your spellcasting ability to determine whether you cast it successfully. The DC equals 10 + the spell’s level. On a failed check, the spell disappears from the scroll with no other effect. Once the spell is cast, the words on the scroll fade, and the scroll itself crumbles to dust.

The level of the spell on the scroll determines the spell’s saving throw DC and attack bonus, as well as the scroll’s rarity, as shown in the Spell Scroll table.
Spell Scroll (table)

A wizard spell on a spell scroll can be copied just as spells in spellbooks can be copied. When a spell is copied from a the copier must succeed on an Intelligence (Arcana) check with a DC equal to 10 + the spell’s level. If the check succeeds, the spell is successfully copied. Whether the check succeeds or fails, the spell scroll is destroyed.

Wondrous item, legendary

This 2-foot-diameter black sphere is a hole in the multiverse, hovering in space and stabilized by a magical field surrounding it.

The sphere obliterates all matter it passes through and all matter that passes through it. Artifacts are the exception. Unless an artifact is susceptible to damage from a sphere of annihilation, it passes through the sphere unscathed. Anything else that touches the sphere but isn’t wholly engulfed and obliterated by it takes 4d10 force damage.

The sphere is stationary until someone controls it. If you are within 60 feet of an uncontrolled sphere, you can use an action to make a DC 25 Intelligence (Arcana) check. On a success, the sphere levitates in one direction of your choice, up to a number of feet equal to 5 × your Intelligence modifier (minimum 5 feet). On a failure, the sphere moves 10 feet toward you. A creature whose space the sphere enters must succeed on a DC 13 Dexterity saving throw or be touched by it, taking 4d10 force damage.

If you attempt to control a sphere that is under another creature’s control, you make an Intelligence (Arcana) check contested by the other creature’s Intelligence (Arcana) check. The winner of the contest gains control of the sphere and can levitate it as normal.

If the sphere comes into contact with a planar portal, such as that created by the gate spell, or an extradimensional space, such as that within a portable hole, the GM determines randomly what happens, using the following table.
