Or magic traps. I like the idea of the Disrobe one being followed by Animate Objects, so someone gets attacked by their own clothes and the only way to stop it is to smash their own equipment. Other options are Flesh to Stone -> Stone to Mud -> Purify Water, or Acid Fog + Deltane's Fiery Tentacles + Forcecage.<br/><br/>But if we could get a trigger-creature (or levers to activate, in a room that can scry on the other rooms), then that would also work.<br/><br/>I know the pit trap at the start needs poisoned razor blades on the edge.<br/><br/>Hmm, crossbow-corridors with honey-sponges on the crossbow bolts, followed by something that dumps a tonne of crushed acorns on them, followed by a swarm of squirrels...
