Psyoliths (or psyalith) are forged weapons that utilize a focus, usually in the form of a ring, sphere or prism incapsulated by an elegant and decorative sheathe. Invented first by the dwarves to assist with safe mining after their discovery of Wraithstone.

Though they are engineered to be able to be wielded by anyone with the knowledge on how to do so, they reach their full potential in the (mind) hands of a psyarch.

Psyoliths made with Wraithstone are the most powerful but most unstable. Any other crystalline material that allows the bouncing of aetheriel energy within can be used. They come in pairs or quads and no more than 4 at a time can be wielded by the mind.

They hover around shoulder height when at rest or when firing aetheriel beams. They can also be stowed like other weapons.

As a mind weapon, any intelligent creature can learn to wield them, including Erezu.
