As to the spell zone: pieces are always immune to thir own spell, specifying a zone of only the square they stand on would have no effect. How would you imagine a piece that (passively) burns itself? Or freezes itself, or brakes itself, or protects itself? The latter three already exist as pieces without moves, steppers and iron pieces.
How would you do a piece that hides itself, though?
(I see the problem with the freeze -- though I still wish there could be a KAND option somehow. Or at least K2.)
