Magic Items

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.

You have resistance to psychic damage while wearing this ring.

Wondrous item, Very Rare (requires attunement)
This belt is made from plates of steel embossed with golden filigree connected by metal pins. A fire giants face adorns the buckle. The giant appears to be having a hearty laugh as she wears an enormous smile on her face. While wearing this belt, your Strength score changes to 25. The item has no effect on you if your Strength without the belt is equal to or greater than 25.

Wondrous item, very 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, Control weather, cure wounds (5th level), and wall of thorns.

This cloak reflects the color of the seasons;
* green in summer,
* gold in autumn,
* mottled brown in winter
* and in spring is mottled in pale shades of green and cream.
You gain a + 1 bonus to AC and saving throws while you wear this cloak. This item can be found in the Dungeon Master’s Guide.

This alabaster lance, named "Dream Whirl" by those who created it, is carved with deep swirling patterns that seem to move with you, calming your emotions and silencing surface thoughts.
Also, the original owner's dreams and anger still dwell within the lance. When within 120 feet of an illithid (mind flayer), its kin, or any of its creations, righteous fury radiates from the lance as it darkens into deep blood crimson.

Wondrous item, very rare (requires attunement)
This slender red taper is dedicated to Sseth, the neutral evil yuan-ti god. The candle's alignment can be detected with the detect evil and good spell.
The candle's magic is activated when the candle is lit, which requires an action. After burning for 4 hours, the candle is destroyed. You can snuff it out early for use at a later time. Deduct the time it burned in increments of 1 minute from the candle's total burn time.
While lit, the candle sheds dim light in a 30-foot radius. Any creature within that light whose alignment matches that of the candle makes attack rolls, saving throws, and ability checks with advantage. In addition, a cleric or druid in the light whose alignment matches the candle's can cast 1st-level spells he or she has prepared without expending spell slots, though the spell's effect is as if cast with a 1st-level slot.
Alternatively, when you light the candle for the first time, you can cast the gate spell with it. Doing so destroys the candle.

While wearing this brooch, you have resistance to force damage, and you have immunity to damage from the magic missile spell. This item can be found in the Dungeon Master’s Guide.
This brooch is fashioned from a tiny leaf inlaid in gold and silver. While the leaf is not alive, it changes color depending on the season as if it were.
