Sometimes referred to as crystal golems, psion-killers are typically between 9 and 10 feet tall, weighing in excess of 2,500 pounds. Composed entirely of crystal, they are created as the antithesis of manifesters.

Psion-killers require explicit orders from their creator in order to do anything. They follow instructions literally and are incapable of using tactics or interpreting Strategy. The creator can command the psion-killer if within 60 feet of the construct and the construct can see and hear its creator. In the absence of its creator, the psion-killer will follow its last instruction to the best of its ability, although if attacked, it will defend itself.

Simple, persistent commands work to keep the psion-killer governed if the creator must be absent, including commands such as, “Attack any creatures other than me if they enter this room.”
