Unbalance

Unbalance [minor] by Iczer

'Feeling giddy? must make it hard to walk that girder huh?'

The character can influence the forces of inertia and momentum on a target to interupt and harry a target.
Every round, one target of the character's choosing within 80 feet (and visible) finds himself assailed by fluctuating and varied inertia and momentum. He must make a saving throw (16+ PE bonuses apply).
If he fails his combat bonuses are lowered by one for the round. His timing is off, he miscalculates the force required etc. furthermore, any skill use that requires a fine sense of balance (dancing, motorcycle riding, acrobatics, etc) have a -10% penalty.
He can target himself with this ability granting himself the reverse of the above bonuses as he fine tunes the kinetic forces he tampers with.
Using this ability costs the character one action per melee round.
