I figured that much, yeah, but I didn't get it to work... Oh well, thanks anyway Drakey, I'll keep experimenting.
EDIT: Ok, so it works. Well, works as in worked twice, didn't work the rest of the {insert large number here} times I tried it. Howcome, when I ask it to divide (using an if statment and the current health call before) x with 4 (x being the max health) that it only turns neutral when the health is 0 (or at least, when the health bar is fully red.) ?
Furthermore, can I prevent the monster from being killed? Like stoping the party member, friendly npc, whatever from reducing the monsters health to negativ?
