Intended method: three phase fight where the PC must break a magic shield before I get off a spell (DPS check). Breaking the shield releases a shockwave which either needs to be dodged or cancelled by an optional item (magic earmuffs). Failure to break the shield fails the fight, sends them to the room before (fuck you watch the whole cutscenes again)

Pacifist method: compliment me a couple of times and I won't know what to do with myself. I teleport away, leaving the key
