In this video I go over what I believe is the most powerful beta skill currently in the game and why you should start to upgrade it early this skill does a nice amount of damage but is even better if you want to combine it with perfect parry to decimate bosses health fast.
If you want to have an easy time on bosses this beta skill is the most rounded and has great potential for anyone who is trying to knock down posture as well as activates insanely fast so make sure you upgrade it early to have the strongest start to your game.
