Grave hag's ear is an alchemy ingredient in The Witcher 3: Wild Hunt. It is not needed to craft anything and cannot be dismantled, and thus can only be sold for profit.
It is only dropped by grave hags, one of the crones, and the Wicked Witch.
Notes[]
- Grave hag's ear was originally meant to be dismantled into monster ears, but the relevant part of its item definition is commented-out.
