Hello, hard time on ps4 too for this skill. It work better if you press button very fast : On ps4 i have to press "round" and "R2". If i put a small delay it don't work. If i chain very fast, it works, but not all the time. I don't know the manipulation on x-box controller, just try to be very fast, perhaps it can work....
hello, you have this guide : https://mmosumo.com/black-desert-online-bdo-lahn-guide-2019/ It can be helpfull. For weapon go kzarka, kutum/nouver and dandellion. Don't lose time and money for blue weapon, this is the best thing to do i think, Good luck for you gear
