First off…Icy Veins is meh for as far as build guides go. They get you in the general direction but don’t really drill down to how a build is played.
Second…read this [GUIDE] VileCharge IK6.RK4 - #14 by BagboyBrown-11183
Third…read this Diablo 3 Forums
Thats the original guide off the old forum that has videos from Cendiesel on how to gear and play the build. Let me know if you have any questions. Great barb community here that can get you sorted out if this is the build you want to push with.
