I just thought of a great idea for a combat rogue skill. The following skill you may have heard of from a certain loveable cat girl from an xbox 360 game
Name: I'm gonna beat the crap out of you!
2 Minute cooldown
Pounce and pin the enemy to the ground, stunning him/her out for 5 seconds, then unleash both your weapons with furious rage, causing a total of 40 melee hits after 5 seconds; however after each hit during a combo, weapon damage is reduced down to 4%. Damage reduction may stack up to 5 times.
