Sanguine Urn

Wondrous item, rare (requires attunement)

This gothic-style urn keeps any fluid stored within it as fresh as the day it was poured. As an action a creature can pour the blood of a flesh-and-blood creature that died up to 1 minute ago into the urn. The urn can hold up to 10 quarts of blood poured in this manner. Additionally, a creature can take an action to drink a quart of blood from the urn. A living creature that drinks from the urn in this manner magically regains 40 hit points and is cured of any diseases or poisons. An undead creature that drinks from the urn in this manner instead has advantage on attack rolls, saving throws, and ability checks for 1 minute.

• Curse. When a living creature drinks blood from the urn it must succeed on a DC 18 Wisdom saving throw or be cursed. A creature so cursed cannot gain any benefits from drinking fluids other than blood from a flesh-and-blood creature that is living or that died up to 1 minute ago.
