Amathesian Shard

A purple crystal with sharp rough edges. For full use it requires to be inserted into the arms flash. After a short rest of attaching it as focus, the wound made for the crystal heals perfectly, with a layer of skin that grows over it.

This is a Arcane Focus used by Githyanki casters.

Taken from the halls of the Amathesian Dreadnaught. It also allows the person using it properly to telecommunicate with the other Amathesian Shard users and also allows them to link minds with the Amathesian ships to pilot them. However, the Dreadnaught requires something a lot stronger.
