A psionicist's powers come from their complex mind, unlike a mage which derives almost all of its power from outside elements, the psionicist derives all of its power from its personal resevoir of power, even with all this he still manages to maintain a good physical condition and does fairly well in non-magical combat as well as the occasional wizard's duel However because the psionicist can't maintain concentration on one thing for very long, his powers don't have the same longevity as one whos powers are not directly controlled by his mind
