The game doesn’t tell you about this combo but I’m sure some of you have done it by accident. It ends in a move where you sweep your opponent and knock them to the ground. You can hit downed enemies with either low slash as the alpha doesn’t yet have attacks dedicated to hitting grounded enemies.
Execute the combo by chaining the following attacks. Remember that combos will still go off if you hit your opponent. Combo chains will only reset on enemy dodge or parry.
Stab - Left high slash (not overhead!) - Right low slash
Be advised that it’s quite buggy. You will reset the trainer on whatever tutorial section he was on if you land it on him and if you kill someone with it in the arena, they will still be on the ground the next time you fight them and will vanish if you hit them with a low slash.
Enjoy!
