The Redbrick Dungeon is Mad at you now!

Dungeon spirits exist to torment, breed evil and lure in victims. Adventurers can be entertaining but their comes a time the genius loci has had enough and act out. Adventurers who cheat by running away when they get low on spells or holing p in a room for a rest or make the dungeon look too easy really annoy the dungeon. Resting in a locked room or trying to leave before resources depleted also annoy the dungeon. Basicly when the party try to have a easy time. Possibly making sacrifices to the dungeon might appease it. Feel free to adjust power level to suit your party.
