The Nightmare Chair

Link

The party opens a door to find a small room with only a single only a dusty chair, surrounded by nothing but old bones and dust... surely one of the tired adventurers will want to have a seat?

This cursed artifact was created by ancient Phobicnauts to draw forth the deepest and most terrifying fears of their victims. When seated in the chair, the victim will firmly believe that their greatest nightmare is unfolding in front of them. This nightmare rises in shadow form around the chair, and will torment them endlessly. Those not seated in the chair will only see a change in their companion, changing from sudden rigidness to powerful screams and thrashing, though no amount of conversation will persuade the person in the chair that the shadows are not real. Furthermore, touching bare skin with the victim may cause the would be rescuer to see fearsome shadows of their own.

The person seated in the chair can not, or will not willing stand up and will react with violence if forced. Destroying the chair has a 25% of doing severe physiological trauma to the person seated.
