The Psionicist class is a 'spellcasting' class similar to Mages and Clerics, but with several important differences. Where a Mage's power comes from harnessing external energies present in all matter, and a Cleric's comes from his or her deity, the Psionicist derives all of his or her power from within. Psions are masters of biocentric spells that alter the body on a cellular level, telepathic spells that can cripple the weak-minded, and telekinetic spells that range from simple levitation to complex attack spells.
Although slightly less powerful than mages in terms of spell damage, they make up for it with their versatility and bevy of unique abilities. The Prime Requisite of a Psionicist is intelligence.
