The PoBs are all for Lvl 100 because i got or got pretty close to lvl 100 last leagues, so i usually do only lvl 100 PoBs for myself. But if you are not complete new to this game you should know how to delete some points for a lower lvl tree ;)

First is a Full Unique build using Ice Crash as damage source. Using Voidforge in combination with Elementalist to be reflect proof, Death's Door for Bleed Immunity, Cyclopean Coil for Shock & Freeze Immunity:

Same as a Totem Build:

Then we have a Curbebot, because i like playing Supporter. 4 Blasphemy Curse and Snipers/Assasins Mark for selfcast. Feel free to change to curses to the one you prefer:

Because i wanted to use the new Melee Totems i came up with a Crit Facebreaker Earthshatter Totem Build which abuses the huge amount of Spikes created by 4 Totems. 15 Spikes per Totem -> 60 Spikes. Each Spike 350k damage -> 21m per "pop":

Feel free to use, adapt and give some feedback if you do any of these builds ;)
