Yaga's Cauldron

Baba Yaga's vile magics have seeped into this squat, copper cauldron. As part of casting a spell, throwing its material components into this magic cauldron while it boils for at least 10 minutes with any liquid substance enhances its magic. If it has a duration of 1 minute or longer, the spell's duration becomes 24 hours instead, and it can target any willing creature within the same plane of existence, regardless of range. If that spell is Bestow Curse and the target creature is in the same plane of existence and familiar to you, it can be targeted by the spell regardless of range. All the spell's components are destroyed in the process. When casting a spell that targets a creature, you may substitute the spell's original components with an important heirloom or body part (such as a drop of blood, lock of hair, bit of nail, and the like) that belongs to that creature. In order to yield the cauldron's benefits to a spell that doesn't require material components at all, you must still use one of the aforementioned items.
