Well, the only way to survive for 5 turns is by guarding, which combined with heals makes your health remain above 50%.
Something else to tweak. haha. Thanks :) For now, just try to not guard. I didn't account for guarding.
I think the awkward part about it is that it feels much less like an RPG, where you *are* supposed to optimize combat to win, and a lot more like a puzzle game, where you figure out what the correct arbitrary sequence is.
Ah. Sorry. :D
