Found a way to disable Blood Rage's activation sound!

if you hide the aura with the mtx "invisible buff effect" the activation sound goes away!

now i can put it on left click without losing my mind!

i stumbled across this today while trying to find a way to disable it

afaik it's not public knowledge because i couldn't find anything on the subject matter, but i may be wrong

I am running a Berserker Ground Slam build and I use Blood Rage all the time. To be honest, I didn't notice the sound effect until now. But I only need to activate it once whenever I enter a new map. So I am not really bothered by it.
