Next question from the peanut gallery. Can a demon or lesser demon grant himself a wish? If so, could he then use said wish to do triple damage on his strike against the wizard who had the temerity to summon him?

If so that would seem to elevate the chances of the wizard not surviving the attempt and making it less likely to try.
