Magic Items

Weapon (longsword), rare (requires attunement)
This item appears to be a longsword hilt. While grasping the hilt, you can use a bonus action to cause a blade of pure radiance to spring into existence, or make the blade disappear. While the blade exists, this magic longsword has the finesse property. If you are proficient with shortswords or longswords, you are proficient with the sun blade.
You gain a +2 bonus to attack and damage rolls made with this weapon, which deals radiant damage instead of slashing damage. When you hit an undead with it, that target takes an extra 1d8 radiant damage.
The sword’s luminous blade emits bright light in a 15-foot radius and dim light for an additional 15 feet. The light is sunlight. While the blade persists, you can use an action to expand or reduce its radius of bright and dim light by 5 feet each, to a maximum of 30 feet each or a minimum of 10 feet each.

Wondrous item, rare (requires attunement)

An Ioun stone is named after Ioun, a god of knowledge and prophecy revered on some worlds. Many types of Ioun stone exist, each type a distinct combination of shape and color.

When you use an action to toss one of these stones into the air, the stone orbits your head at a distance of 1d3 feet and confers a benefit to you. Thereafter, another creature must use an action to grasp or net the stone to separate it from you, either by making a successful attack roll against AC 24 or a successful DC 24 Dexterity (Acrobatics) check. You can use an action to seize and stow the stone, ending its effect.

A stone has AC 24, 10 hit points, and resistance to all damage. It is considered to be an object that is being worn while it orbits your head.

Awareness (Rare). You can’t be surprised while this dark blue rhomboid orbits your head.

Wondrous item, rare (requires attunement by a bard)

An instrument of the bards is an exquisite example of its kind, superior to an ordinary instrument in every way. Seven types of these instruments exist, each named after a legendary bard college. The following table lists the spells common to all instruments, as well as the spells specific to each one and its rarity. A creature that attempts to play the instrument without being attuned to it must succeed on a DC 15 Wisdom saving throw or take 2d4 psychic damage.

You can use an action to play the instrument and cast one of its spells. Once the instrument has been used to cast a spell, it can’t be used to cast that spell again until the next dawn. The spells use your spellcasting ability and spell save DC.

You can play the instrument while casting a spell that causes any of its targets to be charmed on a failed saving throw, thereby imposing disadvantage on the save. This effect applies only if the spell has a somatic or a material component.

Spells: Fly, invisibility, levitate, protection from evil and good, stone shape, wall of fire, wind wall

Wondrous item, very rare (requires attunement)
While you wear this helm, you gain a +1 bonus to AC and remain aware of your surroundings even while you’re asleep, and you have advantage on Wisdom (Perception) checks that rely on sight.
As a bonus action, you can cast the see invisibility spell from the helm. Once this property of the helm is used, it can’t be used again until the next dawn.

Staff, very rare (requires attunement)
This transparent crystal staff can be wielded as a magic quarterstaff that grants a +3 bonus to attack and damage rolls made with it.
Altered Outcome. The staff has 6 charges. As a bonus action, you can expend 1 of the staff’s charges to give yourself or one other creature that you can see a d4. The recipient can roll this d4 and add the number rolled to one ability check, attack roll, damage roll, or saving throw it makes before the start of your next turn. If this extra die is not used before then, it is lost.
If you expend the staff’s last charge, roll a d20. On a roll of 9 or lower, the staff becomes a nonmagical quarterstaff that breaks the first time it scores a hit and deals damage. On a roll of 10 or higher, the staff regains 1d6 of its expended charges.

Weapon (warhammer), very rare (requires attunement by a dwarf)

You gain a +3 bonus to attack and damage rolls made with this magic weapon. It has the thrown property with a normal range of 20 feet and a long range of 60 feet. When you hit with a ranged attack using this weapon, it deals an extra 1d8 damage or, if the target is a giant, 2d8 damage. Immediately after the attack, the weapon flies back to your hand.

Rod, very rare (requires attunement)

While holding this rod, you can use your reaction to absorb a spell that is targeting only you and not with an area of effect. The absorbed spell's effect is canceled, and the spell's energy – not the spell itself – is stored in the rod. The energy has the same level as the spell when it was cast. The rod can absorb and store up to 50 levels of energy over the course of its existence. Once the rod absorbs 50 levels of energy, it can't absorb more. If you are targeted by a spell that the rod can't store, the rod has no effect on that spell. When you become attuned to the rod, you know how many levels of energy the rod has absorbed over the course of its existence, and how many levels of spell energy it currently has stored. If you are a spellcaster holding the rod, you can convert energy stored in it into spell slots to cast spells you have prepared or know. You can create spell slots only of a level equal to or lower than your own spell slots, up to a maximum of 5th level. You use the stored levels in place of your slots, but otherwise cast the spell as normal. For example, you can use 3 levels stored in the rod as a 3rd-level spell slot. A newly found rod has 1d10 levels of spell energy stored in it already. A rod that can no longer absorb spell energy and has no energy remaining becomes nonmagical.

This item is found on Magic Item Table H in the Dungeon Master’s Guide.

Wondrous item, very rare (requires attunement)

This fine garment is made of black silk interwoven with faint silvery threads. While wearing it, you gain the following benefits:

You have resistance to poison damage.
You have a climbing speed equal to your walking speed.
You can move up, down, and across vertical surfaces and upside down along ceilings, while leaving your hands free.
You can't be caught in webs of any sort and can move through webs as if they were difficult terrain.
You can use an action to cast the web spell (save DC 13). The web created by the spell fills twice its normal area. Once used, this property of the cloak can't be used again until the next dawn.
Delver. While underground, the bearer of this item always knows the item's depth below the surface and the direction to the nearest staircase, ramp, or other path leading upward.

Wondrous Item, Very Rare (Requires Attunement by a Wizard)

This pointed hat has the following properties.

Spellcasting Focus. While holding the hat, you can use it as a Spellcasting Focus for your Wizard spells. Any spell you cast using the hat gains a special Somatic component: you must reach into the hat and “pull” the spell out of it.

Unknown Spell. While holding the hat, you can try to cast a level 1+ spell you don’t know. The spell must be on the Wizard spell list, it must be of a level you can cast, and it can’t have Material components costing more than 1,000 GP. Once you decide on the spell, you must expend a spell slot of the spell’s level. Then, to determine whether you cast the spell, make an Intelligence (Arcana) check (DC 10 plus the spell’s level). On a successful check, you cast the spell using its normal casting time, and you can’t use this property again until you finish a Short or Long Rest. On a failed check, you fail to cast the spell and a random effect occurs instead, determined by rolling on the following table.

Any spell you cast from the hat uses your spell save DC and spell attack bonus.

This book contains memory and logic exercises, and its words are charged with magic. If you spend 48 hours over a period of 6 days or fewer studying the book's contents and practicing its guidelines, your Intelligence score increases by 2, as does your maximum for that score. The manual then loses its magic, but regains it in a century.

The typical crystal ball, a very rare item, is about 6 inches in diameter. While touching it, you can cast the scrying spell (save DC 17) with it.
While scrying with the crystal ball, you have truesight with a radius of 120 feet centered on the spell’s sensor.
