Hi guys. Im struggling with building my cyclone marauder. I only have 3000 damage on cyclone when people having hundreds of thousand. My question is how to build up the damge on the skill? Im new to the gamd and all the help would be really apreciate thanks

Im playing cyclone of tumult Im pure physical with high attack speed and leech as a Berserker. Awaken melee, awaken brutality, pulverize, cyclone of tumult, focased channeling and fist of destruction. Get a good axe and take the two ander and axe nods in my hideout Im at 179k but once my rage is cspped its around 800k x3.45 so 2.5 mil per sec.
