Conditions for special kill:
Monster HP (after death): Less than or equal to - ( MaxHP + 2 * Defense ) / 10
AND: Random value from 1 to 5 = 5.
Is this what happens after a normal kill?
Of course, this won't happen if the victim (I mean "monster") is killed by a special move.
What I ment was that when the player can kill a monster in one blow, why not make look kool? AND do maximum damage.
