What would you add to Heroes? (creative ideas only!)

Okay, since we've started this topic, I'll add my own bit of craziness. How about a spell that allows a hero to travel THROUGH TIME, a kind of analog to Dimension Door – let's call it Temporal Portal, for example? Or a combat spell – Balefire (the idea belongs to R. Jordan). The stack that receives damage disappears along with the result of its actions for a certain time (depending on the caster's SP), meaning that all stacks affected by it, for example, during its last turn, are restored! If heroes can be made THREE-dimensional, why not FOUR? P.S. Please don't take this seriously; this topic just inspired me.
