In one smooth motion, the creature called Chrak leaps into the air, draws the strange crescent weapons off of his pack, and lands atop one of the rats. Suddenly those blades don't seem so much odd as efficient.

Actions -
As a Move action, draw weapons and Jump into square J-10. As a Standard action, attack with primary crescent sword at -3/+6 Power Attack.
Attack Roll:
(1d20+7)[20](27) threatens a Crit
Damage Roll:
(2d8+13)[5][5](23) x2 = 46
Jump check (mostly a formality):
(1d20+50)[19](69) (not a typo)
Also, if RoC deems it appropriate Chrak takes falling damage. As Chrak wouldn't attempt to fall more than 6-7 feet, I don't think this is necessary. However, it is a DM call.
