Trapsmith: Stunning Switch

Trapsmith: Stunning Switch

A tomb, you say? [Panehesy's tomb (EA6); photography by Kairoinfo4u]Tomb robbers bring friends or associates with them to help haul away the treasure that they seek. There is safety in numbers, but it also introduces certain group dynamics—exploitable group dynamics such as friendship, caring, trust, and a variety of other deadly virtues.

You are on the southern threshold of a diamond-shaped room. At each point of the diamond, a 10-foot-wide exit leads away to destinations unknown. Each side of the diamond is 40 feet long.

The stunning switch trap activates only when more than one intruder enters the diamond-shaped room. The last person to enter the room within a period of time is the target of the trap. (GMs, adjudicate this as you wish.) He or she is first hit by a power word stun and immediately thereafter is the target of a variant mislead spell. The target becomes invisible, and an illusion of the target sprints toward the eastern exit, spouting gibberish along the way, then vanishes into the corridor.

Stunning Switch Trap     CR 10

Type magical; Perception DC 33; Disable Device DC 33

Trigger sight (true seeing); Reset automatic

Effect spell effect (power word stun)

Effect spell effect (variant of mislead, DC 19 Will save to disbelieve)

Call for initiative. Brave party members will undoubtedly follow their companion into the eastern corridor to save him or her from apparent madness. You can spring a variety of traps on those brave, pursuing souls. On the edge of the eastern threshold you can place a camouflaged spiked pit trap.

Or to make things slightly more interesting, you can spring a cagefight on them. After entering the eastern corridor, a portcullis drops in front and also behind the unfortunate trespasser. One round later, 1d3 girallons are summoned into the impromptu cage.

Cagefight Trap      CR 7

Type mechanical and magical; Perception DC 31; Disable Device DC 31

    How do you guys recommend not tipping the other party members off to the fact that the “crazy PC” is actually still in the room? Seems like you’d have to take the affected member away from the other players and tell them what’s up.

  2. Power stun has no save, so informing the player of his fate is not really necessary.

    Taking him apart and telling him that he won’t see action for a number of rounds is workable.
    Telling the player in front of the group that he needs to beat a very high Will DC to snap out of it could also work. You effectively only need to continue the ruse until they reach trap #2.

    I think keeping the rest of the group in the dark is best.
