Thieving Vial

Wondrous item, rare

When another creature within 30 feet of you uses an action to drink a potion, if you have the thieving vial in hand you can use your reaction to steal that potion and store it in the thieving vial. The creature that had attempted to drink the potion gains no benefit from it. The potion remains stored in the thieving vial indefinitely and can be drunk by you or anyone else as a normal potion of its type. You cannot steal additional potions while the thieving vial holds a potion, and you must complete a long rest before you attempt to use the thieving vial again.
