From publisher blurb: The Mentalist is a new class for the Center Space or other OGL games. It is the third of a four volume series--each presenting new psionically themed classes and races. Volume 3 introduces the Mentalist class, which uses their insight and senses to enhance their combat abilities and skills. This volume does not require Volume 1 or 2 to use. Volume 3 includes: The Mentalist class (more or less a replacement of the Unseen class). Mentalists choose one of four specializations: The Detective--an expert who uses their keen insight to acquire information. The Sneak--a rogue who uses their uncanny senses to keep out of sight. The Con--a charlatan who uses their powers of observation to deceive others. The Mystic--a psychic who uses their deep insight speak to spirits and manipulate minds. One new race--the Sissith: a race of cunning and stealthy assassins.
