Ooooooh. *penny drops*

All health cost champions cannot kill themselves with their abilities, their health will only go down to 1 - so they can't. Mordekaiser is actually the king of surviving on 1 health - he makes Tryndamere look like a pansy. ;)

I think Yorick's ultimate used to have health decay, but since it only lasts for a fixed duration I'm not sure how similar it'd be.

Yeah, I guess he would be the only champion who can die with a shield up. Is that a problem? I mean, he's already dead. :O
