The Investigators have to destroy and object found in a certain room.Keeper has to drive all Investigators insane. With 4 Investigators, I can get enough threat to Summon all Shogoths (2), Hounds(2), Zombies (4)and Cultists (6) within 16 turns,w, with 28 threat left over for other nasty stuff.Then I keep getting more threat after turn 16 for nasty stuff. In addition there are nasty event cards.The Investigators will have to go in a room with all those nasty things, evade to explore to get the object, evade to destroy the object, take all kinds of horror checks...I have to kill alll Investigators or have the remaining ones go insane. Not hard in such a room. How is this not broken?
