Inertia - This staff is able to store kinetic energy. As it builds from being in constant motion it will eventually burst forth knocking back and rendering your opponent helpless.
2% on hit chance to knock an enemy back 10 feet and to the ground. (DC40 Str check VS knockdown DC40 Fort VS Stun No save vs knockback). Sequential saves every 2 secconds. (think of hitting someone in the chest with a big stick they fly back 10 feet and get knocked down) (similar to how minotaur charge works but with a stun ability)

After your years in the limelight you have learned to avoid attention when its not wanted. But when the occasion demands it, you can strike out with great fury. Walk softly but carry a big stick.

(then if acro III gets cartwheel strike...Inertia knocks them back.. dazes them, then carwheel in to finish em off... sweet)
Something like that anyway.
