Idlewild doesn't seem to reset self-damage properly, at least if it's been damage-buffed. Problematic if something has been Rile Up.
The Bat badge may be related too.
(This is probably demo-only. Also, it was nonobvious from the game itself that the full version was available yet. Also also, I think a cool Modifier would be "start with Countdown Badge: must equip, makes all stones clear, adds Streak Ender to equipped spell". Probably rank-neutral?)
