So I've done the shadow prop thing to summon the dark grigori like about three times now. You have to give the food packs that he drops to the mingebag detector (the traffic cone). Whenever I'm low on health, the mingebag detector heals me, with bonus suit energy. I've played on this map for ages now and can't find anything else. Even when I go in the vent, the wall is blank and no music plays. What should I do now?
