Mindcrafters are the psion Class that specializes in confusing and killing their enemies with their brain. The catch is that the target has to possess a mind for it to work - thus, Mind Blast, Confusion Blast and their upgrades do not work on mindless beings. Worse, linking to undead damages the caster. Until they reach lvl 15 and unlock Telekinetic Blast, the player will have to find alternative means of dealing with both.
