Caster's 4-shot attack string can be interrupted by using a Special attack at any point during the string to fire off a new spell. Using Special after the first shot shoots a short-ranged Ice Blast that lingers for a couple of seconds and freezes the enemy in place for a short while!
The momentum and knockback of the last attack used before Ice Blast wears off will be applied after the freeze period ends.
(maybe we can try and make it like Zelda where the momentum of each move builds up, but that would make some super crazy hilarious glitches we do not intend)
