||Has no practical use.
Can be found on the floor close to Plains of Havoc Cyclops encampment, the Tiquanda Tarantula Caves and at the Demon Skeleton spawn in the Pits of Inferno. It also spawns in Ragnir. It can most likely also be found in the other Barbarian settlements, but this has not been confirmed yet.
Was considered to be a rare item for a long time, until it became an official spawn in PoH and in PoI.
