Not sure if this would damage the intended game but would it be possible to have hypnotic spirals be lost on a backfire? It feels like if you dont get a hypnotic spiral or a corrupting potion before the round with a witch that has it, its essentially a loss regardless of how you play, with 4 spirals every time you fill a potion you go -4 persistantly with no means of getting rid of them.
Possible suggestion
Hypnotic spirals lost on backfire
(HOWEVER) each one adds a +1 to a potions backfire effect, you will still lose if it gets out of hand, but you have an option to backfire yourself early and still get back in the game, vs stare down a death spiral (HURHURHUR) and begrudgingly restart
