Magic Items

Ring, rare (requires attunement)
You gain a +1 bonus to AC and saving throws while wearing this ring.

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.

Armor (plate), legendary (requires attunement)
While wearing this armor, you have resistance to one of the following damage types: bludgeoning, piercing, or slashing. The GM chooses the type or determines it randomly.
Curse. This armor is cursed, a fact that is revealed only when an identify spell is cast on the armor or you attune to it. Attuning to the armor curses you until you are targeted by the remove curse spell or similar magic; removing the armor fails to end the curse. While cursed, you have vulnerability to two of the three damage types associated with the armor (not the one to which it grants resistance).

Wondrous item, rare (requires attunement)
While wearing these bracers, you gain a +2 bonus to AC if you are wearing no armor and using no shield.

Weapon (shortsword), rare
You gain a +1 bonus to attack and damage rolls made with this magic weapon.
When you hit a giant with it, the giant takes an extra 2d6 damage of the weapon’s type and must succeed on a DC 15 Strength saving throw or fall prone. For the purpose of this weapon, “giant” refers to any creature with the giant type, including ettins and trolls.
The sword’s name (“Longtooth”) is engraved into the blade in Gnomish.

Wondrous item, rare
This object appears as a wooden box that measures 12 inches long, 6 inches wide, and 6 inches deep. It weighs 4 pounds and floats. It can be opened to store items inside. This item also has three command words, each requiring you to use an action to speak it.
One command word causes the box to unfold into a boat 10 feet long, 4 feet wide, and 2 feet deep. The boat has one pair of oars, an anchor, a mast, and a lateen sail. The boat can hold up to four Medium creatures comfortably.
The second command word causes the box to unfold into a ship 24 feet long, 8 feet wide, and 6 feet deep. The ship has a deck, rowing seats, five sets of oars, a steering oar, an anchor, a deck cabin, and a mast with a square sail. The ship can hold fifteen Medium creatures comfortably.
When the box becomes a vessel, its weight becomes that of a normal vessel its size, and anything that was stored in the box remains in the boat.
The third command word causes the folding boat to fold back into a box, provided that no creatures are aboard. Any objects in the vessel that can’t fit inside the box remain outside the box as it folds. Any objects in the vessel that can fit inside the box do so.

Wondrous item, uncommon
These crystal lenses fit over the eyes. While wearing them, you can see much better than normal out to a range of 1 foot. You have advantage on Intelligence (Investigation) checks that rely on sight while searching an area or studying an object within that range.

Wondrous item, rare
This delicate silver chain has a brilliant-cut black gem pendant. While you wear it, poisons have no effect on you. You are immune to the poisoned condition and have immunity to poison damage.

Armor (Any Heavy Armor), Rare (Requires Attunement)
This magic armor appears as a pot of bubbling black ichor. When you attune to it, the ichor adheres to and contours to your skin, and the pot disappears. The armor can be worn under normal clothes, and it doesn’t impede bodily functions. Once you put it on, it can’t be removed unless you choose to do so or you die, at which point the pot reappears and the ichor flows back into it.
While wearing the armor, you have resistance to poison damage. The armor also doesn’t impose disadvantage on Dexterity (Stealth) checks.

Wondrous Item, Rare (Requires Attunement)
You can use an action to blow this horn to cast one of the following spells from it: Arms of Hadar, Fog Cloud, Gust of Wind, or Web. If the spell requires a saving throw, the spell save DC is 13.
Once the horn has been used to cast a spell, it can’t be used to cast that spell again until the next dawn.

Wondrous Item, Very Rare (Requires Attunement)
This magic vehicle is a boat 10 feet wide and 30 feet long. It has four legs that propel it across land and water. It has a walking and swimming speed of 20 feet, but it can’t travel underwater. The boat moves according to your spoken directions while you are riding it, and creatures of your choice gain a +1 bonus to their Armor Class while on the boat.
The boat can transport up to 1,000 pounds without hindrance. It can carry up to twice this weight, but it moves at half speed if it carries more than its normal capacity.

Wondrous item, rare (requires attunement by a wizard) 3 lb. This brass disc of articulated, concentric rings unfolds into an armillary sphere. As a bonus action, you can unfold it into the sphere or back into a disc. When found, it contains the following spells, which are wizard spells for you while you are attuned to it: augury, divination, find the path, foresight, locate creature, and locate object. It functions as a spellbook for you, with spells encoded on the rings. While you are holding the archive, you can use it as a spellcasting focus for your wizard spells. The archive has 3 charges, and it regains 1d3 expended charges daily at dawn. You can use the charges in the following ways while holding it: If you spend 1 minute studying the archive, you can expend 1 charge to replace one of your prepared wizard spells with a different spell in the archive. The new spell must be of the divination school. When a creature you can see within 30 feet of you makes an attack roll, an ability check, or a saving throw, you can use your reaction to expend 1 charge and force the creature to roll a d4 and apply the number rolled as a bonus or penalty (your choice) to the original roll. You can do this after you see the roll but before its effects are applied. Minor Property: Harmonious Attuning to this item takes only 1 minute.

Wondrous item, common
This fearsome steel helm makes your eyes glow red while you wear it.
Minor Property Language: Thayan

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.

Wondrous item, uncommon
This box contains a set of parchment cards. A full deck has 34 cards. A deck found as treasure is usually missing 1d20 - 1 cards.
The magic of the deck functions only if cards are drawn at random (you can use an altered deck of playing cards to simulate the deck). You can use an action to draw a card at random from the deck and throw it to the ground at a point within 30 feet of you.
An illusion of one or more creatures forms over the thrown card and remains until dispelled. An illusory creature appears real, of the appropriate size, and behaves as if it were a real creature (as presented in the Monster Manual), except that it can do no harm. While you are within 120 feet of the illusory creature and can see it, you can use an action to move it magically anywhere within 30 feet of its card. Any physical interaction with the illusory creature reveals it to be an illusion, because objects pass through it. Someone who uses an action to visually inspect the creature identifies it as illusory with a successful DC 15 Intelligence (Investigation) check. The creature then appears translucent.
The illusion lasts until its card is moved or the illusion is dispelled. When the illusion ends, the image on its card disappears, and that card can't be used again.

Ring, very rare (requires attunement)
While wearing this ring, you can cast the telekinesis spell at will, but you can target only objects that aren’t being worn or carried.

Wondrous item, rare
A figurine of wondrous power is a statuette of a beast small enough to fit in a pocket. If you use an action to speak the command word and throw the figurine to a point on the ground within 60 feet of you, the figurine becomes a living creature. If the space where the creature would appear is occupied by other creatures or objects, or if there isn’t enough space for the creature, the figurine doesn’t become a creature.
The creature is friendly to you and your companions. It understands your languages and obeys your spoken commands. If you issue no commands, the creature defends itself but takes no other actions.
The creature exists for a duration specific to each figurine. At the end of the duration, the creature reverts to its figurine form. It reverts to a figurine early if it drops to 0 hit points or if you use an action to speak the command word again while touching it. When the creature becomes a figurine again, its property can’t be used again until a certain amount of time has passed, as specified in the figurine’s description.
Bronze Griffon (Rare). This bronze statuette is of a griffon rampant. It can become a griffon for up to 6 hours. Once it has been used, it can’t be used again until 5 days have passed.

Weapon (mace), rare (requires attunement)
This magic weapon has 3 charges. While holding it, you can use an action and expend 1 charge to release a wave of terror. Each creature of your choice in a 30-foot radius extending from you must succeed on a DC 15 Wisdom saving throw or become frightened of you for 1 minute. While it is frightened in this way, a creature must spend its turns trying to move as far away from you as it can, and it can’t willingly move to a space within 30 feet of you. It also can’t take reactions. For its action, it can use only the Dash action or try to escape from an effect that prevents it from moving. If it has nowhere it can move, the creature can use the Dodge action. At the end of each of its turns, a creature can repeat the saving throw, ending the effect on itself on a success.
The mace regains 1d3 expended charges daily at dawn.

Wondrous item, rare
This rope is 30 feet long and weighs 3 pounds. If you hold one end of the rope and use an action to speak its command word, the other end darts forward to entangle a creature you can see within 20 feet of you. The target must succeed on a DC 15 Dexterity saving throw or become restrained.
You can release the creature by using a bonus action to speak a second command word. A target restrained by the rope can use an action to make a DC 15 Strength or Dexterity check (target’s choice). On a success, the creature is no longer restrained by the rope.
The rope has AC 20 and 20 hit points. It regains 1 hit point every 5 minutes as long as it has at least 1 hit point. If the rope drops to 0 hit points, it is destroyed.

Armor (Plate Armor), Very Rare

While wearing this armor, you gain a +2 bonus to Armor Class. In addition, if an effect moves you against your will along the ground, you can take a Reaction to reduce the distance you are moved by up to 10 feet.
