Grim almost smiled as the larger man took the bait and attacked Brando. Almost like I scripted this out ... now for my part ...

As the big man swung, Grim leapt forward, letting just a bit of his momentum fuel the power behind his own strike.

Not sure how this would work, but I'd like to use my movement (fueled just a bit by my supernatural speed) to jump forward and smash into the big guy. Maybe an Athletics skill for a Maneuver bonus?
