Hi!
Not sure if this was already reported, I couldn’t find a post. Anyway, if you allocate Press The Attack with Puncture and trigger the buff, then channel Flurry, the 20% attack speed buff persists even once the buff is over
I checked from the sound design:
Normal Flurry channel:
audio spectre
2 seconds after Frenzy was (supposedly) over:
audio spectre
I haven’t tried this with other channeled skills however, and I’m not sure this is supposed to be a feature either
