Psychic Force, in part, reads, "The user may use his or her Will as a ranged attack, doing damage on the Fists column."

Most people just think of some kind of blasting mental attack that sends their opponent flying across the room or wracked with pain from an unseen source.

Again, that's not what it says.

Remember that damage is always applied to all scores, thus "damage" can be represented by anything; take this ability + Perception + Hint and you've just become a walking nightmare factory. (Gradual) Damage represents the target sinking further and further into depression. At double his Stamina in lasting damage he just can't take it anymore and throws himself off a ten story building, an apparent suicide. [1]
