Magic Items

Armor (shield), rare
This shield is fashioned of dull, black steel and festooned
with hundreds upon hundreds of human teeth. Whenever
the wielder of the shield is presented with an opportunity
to act in a selfish or malevolent way, the item heightens
the wielder’s urge to do so.

This set of sky blue magical studded leather armor once belonged to a cloud giant resident of Skyelinjeheim. It resizes to fit its wearer, and images of translucent white clouds drift slowly across the armor constantly.

Wondrous item, very rare (requires attunement)

This shield is made from the scale of an ancient white dragon. It has a rune burned into its outward-facing side. A character who examines the rune and succeeds on a DC 20 Intelligence (History) check recognizes it as an uven (“enemy” in Giant) rune that confers great power.

While holding the shield, you benefit from the following properties.

Winter’s Friend. You are immune to cold damage.

Deadly Rebuke. Immediately after a creature hits you with a melee attack, you can use your reaction to deal 3d6 necrotic damage to that creature.

Bane. You can cast the bane spell from the shield (save DC 17). The spell does not require concentration and lasts for 1 minute. Once you cast the spell from the shield, you can’t do so again until you finish a short or long rest.

Gift of Vengeance. You can transfer the shield’s magic
to a nonmagical weapon by tracing the uven rune on the weapon with one finger. The transfer takes 8 hours of work that requires the two items to be within 5 feet of each other. At the end, the shield is destroyed, and the rune is etched or burned into the chosen weapon. This weapon becomes a rare magic item that requires attunement. It has the properties of a +1 weapon. The bonus increases to +3 when the weapon is used against one of the following creature types, chosen by you at the time of the magic weapon’s creation: aberrations, celestials, constructs, dragons, elementals, fey, fiends, giants, or undead.

This item is found in Waterdeep: Dungeon of the Mad Mage.

Wondrous Item, rare

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 GM.
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.

The ring is in the shape of a kraken head

[rare, attunement] -- While you wear this ring, difficult terrain doesn't cost you extra movement. In addition, magic can neither reduce your speed nor cause you to be paralyzed or restrained.

The ring appears to be made of smooth, gray, wooden thorny vines in the a. A piece of moonstone forms the center of the ring. When the ring's magic is activated, the wearer feels a harmless flash of pain as if his finger is pierced by a thorn - a drop of blood as payment to the Earthmother.

Wondrous item, common
While smoking this pipe, you can use an action to exhale a
puff of smoke that takes the form of a single creature, such
as a dragon, a flumph, or a froghemoth. The form must be
small enough to fit in a 1-foot cube and loses its shape after
a few seconds, becoming an ordinary puff of smoke.
Guardian. The item whispers warnings to its bearer,
granting a +2 bonus to initiative if the bearer isn't
incapacitated.

The Mithril Blade is exquisitely crafted from the finest materials and never becomes dirty. "Miir" means "Priceless" in Elvish.

Wondrous Item, common

This tankard has a stern face sculpted into one side. You can drink ale, wine, or any other nonmagical alcoholic beverage poured into it without becoming inebriated. The tankard has no effect on magical liquids or harmful substances such as poison.

This official Honeybell Habitats mug has the slogan “Show me the HONEY” painted on the side with an illustration of a flying bee. A beverage drunk out of this mug tastes faintly of star thistle honey, before an automated message announces, “Get back to work!”

Guardian. The item whispers warnings to its bearer, granting a +2 bonus to initiative if the bearer isn’t incapacitated.

This helm is decorated with scenes of underwater volcanoes. While you wear it, you can speak and understand Aquan.

This dazzling helm is set with 5 diamonds, 11 rubies, 16 fire opals, and 22 opals. Any gem pried from the helm crumbles to dust. When all the gems are removed or destroyed, the helm loses its magic.

You gain the following benefits while wearing it:

You can use an action to cast one of the following spells (save DC 18), using one of the helm’s gems of the specified type as a component: daylight (opal), fireball (fire opal), prismatic spray (diamond), or wall of fire (ruby). The gem is destroyed when the spell is cast and disappears from the helm.
As long as it has at least one diamond, the helm emits dim light in a 30-foot radius when at least one undead is within that area. Any undead that starts its turn in that area takes 1d6 radiant damage.
As long as the helm has at least one ruby, you have resistance to fire damage.
As long as the helm has at least one fire opal, you can use an action and speak a command word to cause one weapon you are holding to burst into flames. The flames emit bright light in a 10-foot radius and dim light for an additional 10 feet. The flames are harmless to you and the weapon. When you hit with an attack using the blazing weapon, the target takes an extra 1d6 fire damage. The flames last until you use a bonus action to speak the command word again or until you drop or stow the weapon.
Roll a d20 if you are wearing the helm and take fire damage as a result of failing a saving throw against a spell. On a roll of 1, the helm emits beams of light from its remaining gems. Each creature within 60 feet of the helm other than you must succeed on a DC 17 Dexterity saving throw or be struck by a beam, taking radiant damage equal to the number of gems in the helm. The helm and its gems are then destroyed.
