I can say I have witnessed it Proc Yes. I may have some old screen shots since i sold this back in October. Im tryna find confirmation if this speeds up Bladestorms animations because I think it does but im not sure cuz I run Fury and Quickening on Ashs melee but I can confirm that when casting Bladestorm it does Proc indeed
Sorry for the terrible quality but as we all know Bladestorm doesnt have the best camera angles or animations. As seen here Arcane Strike proced while i was in Bladestorm. I have been running Arcane Trickery since it released when Raids/Volt Prime access U16, but Arcane Strike was the second Arcane enhancement i attained and maxed. Its quiet fun but Im not sure if it really speeds up bladestorm significantly, Id like to know if adding 2 maxed Strikes affects the speed of BS but im too attached to Trickery that I careless about Strike.
I hope this was able to provide a bit of info because I still have my doubts but theres no doubt it procs when casting Bladestorm, I wish berserker worked for Bladestorm tho
