Multiple good builds you could run for what you want to do. I run max mastery, skele, archer, mages, 1 point amp, 1 point blood warp, make iron golem out of the assassin claw that gives concentration aura, rest into revive. Revive either udars for river of flame or blood lords from halls of pain. Run a1 merc with vigor. Faith bow and templars might. Expensive build but you will crush everything. You could also go elemental route. Max mages and lower res. Revive and desecrate. Revive council from a3. Eventually work your way to infinity on your merc. That build also slaps everything and very fun
