Magic Items

Martial Melee Weapon (Glaive), very rare
The head of this glaive is not made of metal, and is instead a concentration of Empyrean’s special blood. The blade glitters like, well, glitter, and undulates like mercury. The blood gives the entire weapon, including the shaft, the minor property unbreakable: the item can’t be broken. Special means must be used to destroy it (ie. antimagic field).
Glaive, +3. Melee Weapon Attack, range, 10 ft., 6 (1d10) piercing damage. Heavy, Reach, Two-Handed. You have a +3 bonus to attack and damage rolls made with this magic weapon.

Ring, very rare (requires attunement)

While wearing this ring, you regain 1d6 hit points every 10 minutes, provided that you have at least 1 hit point. If you lose a body part, the ring causes the missing part to regrow and return to full functionality after 1d6 + 1 days if you have at least 1 hit point the whole time.

(minor magical property: Conscientious)

This horn has 4 charges. When you use an action to blow it, one creature of your choice can hear the horn’s blare, provided the creature is within 600 feet of the horn and not deafened. No other creature hears sound coming from the horn. The horn regains 1d4 expended charges daily at dawn.

Marvelous Pigments
Wondrous item, very rare

colors: Blue and red

Typically found in 1d4 pots inside a fine wooden box with a brush (weighing 1 pound in total), these pigments allow you to create three-dimensional objects by painting them in two dimensions. The paint flows from the brush to form the desired object as you concentrate on its image.

Each pot of paint is sufficient to cover 1,000 square feet of a surface, which lets you create inanimate objects or terrain features—such as a door, a pit, flowers, trees, cells, rooms, or weapons— that are up to 10,000 cubic feet. It takes 10 minutes to cover 100 square feet.

When you complete the painting, the object or terrain feature depicted becomes a real, nonmagical object. Thus, painting a door on a wall creates an actual door that can be opened to whatever is beyond. Painting a pit on a floor creates a real pit, and its depth counts against the total area of objects you create.

Nothing created by the pigments can have a value greater than 25 gp. If you paint an object of greater value (such as a diamond or a pile of gold), the object looks authentic, but close inspection reveals it is made from paste, bone, or some other worthless material.

If you paint a form of energy such as fire or lightning, the energy appears but dissipates as soon as you complete the painting, doing no harm to anything.

Wondrous Item, rare

This backpack has a central pouch and two side pouches, each of which is an extradimensional space. Each side pouch can hold up to 20 pounds of material, not exceeding a volume of 2 cubic feet. The large central pouch can hold up to 8 cubic feet or 80 pounds of material. The backpack always weighs 5 pounds, regardless of its contents.

Placing an object in the haversack follows the normal rules for interacting with objects. Retrieving an item from the haversack requires you to use an action. When you reach into the haversack for a specific item, the item is always magically on top.

The haversack has a few limitations. If it is overloaded, or if a sharp object pierces it or tears it, the haversack ruptures and is destroyed. If the haversack is destroyed, its contents are lost forever, although an artifact always turns up again somewhere. If the haversack is turned inside out, its contents spill forth, unharmed, and the haversack must be put right before it can be used again. If a breathing creature is placed within the haversack, the creature can survive for up to 10 minutes, after which time it begins to suffocate.

Placing the haversack inside an extradimensional space created by a bag of holding, portable hole, or similar item instantly destroys both items and opens a gate to the Astral Plane. The gate originates where the one item was placed inside the other. Any creature within 10 feet of the gate is sucked through it and deposited in a random location on the Astral Plane. The gate then closes. The gate is one-way only and can't be reopened.

Staff, rare (requires attunement by a druid)

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 have a +2 bonus to spell attack rolls.

The staff has 10 charges for the following properties. It regains 1d6 + 4 expended charges daily at dawn. If you expend the last charge, roll a d20. On a 1, the staff loses its properties and becomes a nonmagical quarterstaff.

Spells. You can use an action to expend 1 or more of the staff’s charges to cast one of the following spells from it, using your spell save DC: animal friendship (1 charge), awaken (5 charges), barkskin (2 charges), locate animals or plants (2 charges), speak with animals (1 charge), speak with plants (3 charges), or wall of thorns (6 charges).

You can also use an action to cast the pass without trace spell from the staff without using any charges.

Tree Form. You can use an action to plant one end of the staff in fertile earth and expend 1 charge to transform the staff into a healthy tree. The tree is 60 feet tall and has a 5-foot-diameter trunk, and its branches at the top spread out in a 20-foot radius. The tree appears ordinary but radiates a faint aura of transmutation magic if targeted by detect magic. While touching the tree and using another action to speak its command word, you return the staff to its normal form. Any creature in the tree falls when it reverts to a staff.

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.

Wondrous item, rare (requires attunement)

This robe is adorned with eyelike patterns. While you wear the robe, you gain the following benefits:

The robe lets you see in all directions, and you have advantage on Wisdom (Perception) checks that rely on sight.
You have darkvision out to a range of 120 feet.
You can see invisible creatures and objects, as well as see into the Ethereal Plane, out to a range of 120 feet.

The eyes on the robe can’t be closed or averted. Although you can close or avert your own eyes, you are never considered to be doing so while wearing this robe.

A light spell cast on the robe or a daylight spell cast within 5 feet of the robe causes you to be blinded for 1 minute. At the end of each of your turns, you can make a Constitution saving throw (DC 11 for light or DC 15 for daylight), ending the blindness on a success.

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

Ring, rare (requires attunement)

This ring stores spells cast into it, holding them until the attuned wearer uses them. The ring can store up to 5 levels worth of spells at a time. When found, it contains 1d6 − 1 levels of stored spells chosen by the DM.

Any creature can cast a spell of 1st through 5th level into the ring by touching the ring as the spell is cast. The spell has no effect, other than to be stored in the ring. If the ring can’t hold the spell, the spell is expended without effect. The level of the slot used to cast the spell determines how much space it uses.

While wearing this ring, you can cast any spell stored in it. The spell uses the slot level, spell save DC, spell attack bonus, and spellcasting ability of the original caster, but is otherwise treated as if you cast the spell. The spell cast from the ring is no longer stored in it, freeing up space.

Bless and Revivify stored.

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.
