Some notes about Abjurer in rifts. In skosglen he is constantly dying from fire around little trees and from etherborn cold breath. I increased his res to 90 fire, 86 cold. It helps vs fire trees, he is dying not so fast, but still should be teleported if 2 or more trees can't be killed quickly. But etherborns anyway kills him very quickly. And this high res setup costs him a big chunk of dmg. Conclusion: Abjurer just can't survive in skos.
But he is very strong in vizjun and fauzt. With good gear (griffon eye, hide of basilisk, dementia...) and 50% PR, he just destroying necrobots and other mobs and hard to kill there.
