Painful Suggestion Trap
HAZARD 8 +16 (expert)
A hidden rune on the floor under the filth, just past the threshold, triggers an ersatz ghost.
DC 28 Thievery (expert) to remove the rune without triggering it, or Dispel Magic (4th rank; counteract DC 26) to dispel the rune
Counterfeit Haunting (auditory, incapacitation, linguistic, mental)
A living creature moves over the rune
A frightful moan echoes through the room, and a hoarse telepathic voice shouts, "Get out!"
This shout deals 6d12 mental damage to creatures in the room (DC 26 basic Will save). Creatures who fail this saving throw must immediately leave the room and can't willingly reenter it for 1 minute (1 hour on a critical failure).
The trap automatically resets after 1 hour.
