I'm playing falconer ice trap, cold acid vile machine gun, cold umbral blade combo. My ice traps drop my cold acid viles, oblititerating small mobs. When I right-click with my acid viles, my falcion throws then with me, I hit enemies with 6 cold viles per attack with a crazy high throw speed. When I use Arial assault my cold umbrell blades explode into ice. I'm pumping up cold damage and freeze rate multi. Everything is frozen. It is very glass cannon, but thanks to freeze, slow effects, frailty, and blind, I hardly feel the impact. I can freeze most bosses with 1 click of ice trap, and thanks to all the freeze effects, it's never on cd. I am super mana hungry, and the build is better at clearing mobs than bosses, but as I'm scaling up ice vile machine gun, which has unlimited scalability with uncapped poison resist, I think it can go pretty deep. I'm just in empowered monos and it's feeling really good. Once cold shred with ice vials is no longer bugged, I think this could be a top tier build. TBD.
