Yeah, I forgot to state on Iconoclast's merc description that Herd Immunity will remove certain statuses. That's my bad.
As for items, I meant for most of them to be used in bulk outside of combat in-between fights.
I'm definitely going to have to reduce Selene's healing if the fight's taking that long. I'll work on making it less of a slog.
Glad you liked the coven fight tho
