No, build was nerfed to the ground 
Just getting into Grim Dawn. Is this build really nerfed into Oblivion? Was this the nerf bat that did the most dmg…
Dark One’s Gift: reduced Vitality damage modifier for Wendigo Totem to 100.
?
this build didn’t utilize full dark one, it used full wildblood set, which was nerfed pretty harsh.
i’ve tried it recently - always recasting vine (set would give +duration to it) is simply cancerous.
and i believe it should have some major gear tweaks.
As Grey said, the build uses Bloodknight for the long time already. Latest buffs to WB helped a lot, but idk, when I update the guide
