I am playing an Eye of Winter Occultist and I honestly really enjoy it. But I mainly struggle with defenses on this character. I have reshuffled my Passive Tree a few times now. I tried Glancing Blows with a Life on Block Shield, but i had to sacrifice alot of Life to get the Block nodes. In terms of Main Links, I tried Pinpoint with Apex Mode Jewel, which was fine. I tried Badge of Brotherhood and ice Bite, but I didnt like losing Life on my Amulet and it just didnt feel right. Also I dont know how to keep up frenzy on bosses. Right now I am playing with Unleash and the three Unleash nodes
