Source Pathfinder #2.
As the ghouls reach for the haunted PC, she must make a DC 16 Will save to shake off the vision and regain her senses. If she fails, the ghouls grab her and begin to tear and bite at her flesh. Observers see the haunted PC jerk and thrash in the air as if she were being shaken by a mob, and suddenly deep red claw and bite wounds appear on her flesh. The haunted PC takes 6d6 points of damage from the assault (half on a DC 16 Fortitude save), and must make a DC 16 Fortitude save to resist catching ghoul fever.
