How do you recover HP on the enemy's turn? I'd retreat here if double-turning was possible. But it's not. You can't steal the enemy's turn anymore if somehow your CEL surpasses theirs.

And I'm against making it a on-round-end for two reasons. First, we already have Die Hard, second, cinders will kill them, regardless. Cinders, Poison, Lingering Damage, Burn, Curses, Lantern Bearer's Raging Flame.
