The party enters a room with a stone wall and a locked door. The wall has a riddle engraved in it; "The key is found within your head, use the key to paint me red, be aware of what you spurn, for what you give shall be returned." The party must use blood and smear it on the wall (where they get it from is up to them), and a duplicate of what the blood came from emerges out of the wall. The party must fight and defeat the duplicate to unlock the door.
