OK, thinking about a psionic character. But as there are no psionics in the game it is understood that these would have to be created.
The core mechanic of spells is Discard with a chance of Recharge. We were thinking that psionic powers should be Recharge with the option to Discard for increased effect.
The thought is that powers aren't lost when used (unlike spells). But they do take something out of you (power) so they may not be reused quickly - hence Recharge.
