the Resolute Technique node in the dancing strikes skill tree seems to not be working. It is supposed to increase damage to Lethal Mirage and Synchronized Strike for every time Dancing Strikes is used recently (within the last 4 seconds).
I only have an online character to test it so unsure if it affects offline, but with 4/4 in the node neither lethal mirage or synchronized strike appear to be gaining any increased damage after using dancing strikes. There is no visual indicator that im receiving a buff, the tooltip damage/dps of both skills remains the same, and the damage numbers when hitting a dummy remain the same with or without using dancing strikes beforehand.
Was tested using 2 dancing strikes before using the other ability and repeatedly was getting the exact same tooltip numbers and always roughly the same damage numbers on the dummy, obviously not receiving the supposed 120% increased damage it should be getting (60% per use). Will make and provide video if needed.
