The uppercut is a simple combo allowing damage and a strong crowd control lock, rendering the opponent flying in the air for 1 second.
It is easily produced by pressing the UP key and Attack One/Attack Two
(Both attacks produce the same effect and same damage output, the only differences are the aesthetics of a kick uppercut or punch uppercut)
Uppercutting is a invaluable tool for disarming your opponents as it knocks them and their weapon out for 1 second. It is also a significant counter towards Dashing.
Unlike Dashing which has small glitches resulting in the player dashing out of the map, the uppercut is a relatively safe combo with no drawbacks, apart from common weapons.
