Maelstrom: Affects a random object in the room, which starts to give off a sick red light and sucks mortals towards it, who are unable to run away. Mortals will think they'll surely die if they touch the object. If they do touch it they faint or go mad. I know the mortals don't eat or drink in GM but if they did there could be some powers related to that like a power which makes drink or food suddenly taste horribly, slightly scaring mortals and making them spit it out into each other's faces . Or like a power which makes the food start to crawl off the plate or spurt maggots like in Poltergeist.
Death be thy compass
Nothing better than a bucket of raw eggs and a mug of goose fat early in the morning!
There are. Each Terror Incarnate is unique. Wait, I'm wrong, Maxine Factor's and Blue Murder's power is the same. Still there's The Thing in the Mirror used by Lady Rose, Blair Wisp's Hypnotic Image and probably more, I don't remember.
I was thinking about additional options according to the fetter a haunter is bound to. Say if Cogjammer is bound to a car, there could be a 'chase' option to use against mortals with fears of being hunted.
