i think all the builds are ok, and strong but u have to think wich u want, its a pvp or pve build.
this build its good for pve but if u want for pvp u have to consider now u-u
in cbt2 you can reset yours skill and test other more often. dont bother about it.
Use Earthquake, not reflect shield. Also, don’t use flare. And only put one point into hell breath.
Energy Bolt 1/5 and use Earthquake 4/5 remove flame and go Flame Ground 10/10 make Fire Wall 10/10 and go Fireball 10/10
