It is Corkscrew mastery. It's a skill best pumped to level 7 or higher if you maxed out gorgeous combo.
Hard Punch mastery just adds frames of superarmor and a higher critical ratio, a must have for high level pvp.

Woo for the past few pages it became an infighter thread!

Combination mastery
At level 7 this gives an extra hit for machine jab. After the downward slam from the ordinary last hit, the extra hit is an uppercut which throws the opponent high up. Combine this with at least level 7 technical mastery and you get vacuum machine jab which has a Very strong suction power for a level 30 skill and superarmor status. After the hit up, you are able to unleash any form of combo you want. With shadow boxer on, it's almost a definite win once you manage to land the enhanced machine jab. Just follow in with throw up skills like ducking upper, second upper, chopping hammer. The throw up is also high enough to chain death combo even if the opponent is wearing plate.

Another way to use this is against fast opponents. Use sidewinder for it's range to knock the opponent towards you, then just use vacuum machine jab.

One more way to use it is to prevent from missing the machine jab's last 2 hits if the opponent is already knocked up. If you do not have vacuum machine jab, and the opponent is in the air when you use it, the skill will just juggle the opponents making your last heavy hits miss. With vacuum, the opponent will be sucked into your machinegun punch even while in the air, allowing your heavy hits to hit and throw him back up. Of course, the distance of how high the opponent is up in the air also affects how effective the vacuum will be.

Technical mastery
Level 4 is where you get sway body blow. A common way to use this is in a normal combo. While using X,X,X,X where the last hit throws them up, use sway body blow as it has a dash forward effect which allows you to cover the distance of sway, unlike upper or straight. Then just follow up with a sway chopping hammer and do whatever you want.

Another way to use technical mastery is to do a freak sway straight and attack the opponent from the blindspot. Immediately follow up with ducking chopping hammer and you're on your way to another death combo.
