When using Shift to throw Blade Shield shurikens using Ethereal Blades, it will cause hits of Dancing Strikes to not register as a hit for Rhythm and cause your stacks to drop constantly, often even if you’re in the middle of a huge pack hitting multiple enemies. Saw a thread from June 2021 of the same thing
Still not fixed apparently, really obnoxious bug that pretty much entirely breaks this build.
Nice to see I’m not the only one.
I wanted to report this bug as well and found the thread you mentioned, this occurs pretty consistently and doesn’t really allow you to use Rhythm from Dancing Strikes with Blade Barrier from Shurikens which causes you to lose a lot of armour.
