knockout to death battle system

[Estherbunny]

I recently had an idea to use a knockout to death system for my battles, where if a battlers HP drops below a certain number they will be 'outcold'. They can come back from that by (maybe) not getting hit for several rounds or being revived with a potion, but some enemies will continue to attack them when they are down. If their HP reaches 0, even if it's only one character who's died. It will be a game over. I think a defend fallen mode would be beneficial if I had a setup like that, but what I want to know is if this system is possible at all? Without scripting that is

Are you looking for the character to be untargetable while temporarily knocked out?

My goal is to have only some enemies target the character when they're down.
