"The Psychocephalid is a highly intelligent, squidlike alien that skulks through dungeons in search of humanoid corpses. It devours the brain of its chosen host, then anchors itself to the empty skull and puppets the corpse as its own body. To conceal its true nature, it shrouds the decaying frame in heavy robes, revealing only the tentacled mass that serves as its head..."

More Info...

The Psychocephalid...

When a Psychocephalid is not attached to and controlling a host body, it becomes far less dangerous. In this unattached state, Psychocephalids are extremely rare to encounter.

Without a host, a Psychocephalid can scurry across the ground at high speed (fast Movement Speed) and can attack with its tentacles and make normal defense rolls. However, it loses access to all magical abilities, since a Psychocephalid requires a host body to cast spells or use any magic...
