Grasping Vines with Devouring Swarm, big AoE and bleed dots. Go to Forgotten Gods as soon as you finish act 1, you can get Sand Effigy from enemies very early, and that converts the physical in Grasping Vines to Vitality and gives it more bleeds damage.
The build is really easy to gear, easy to pilote, on top of having a low impact gameplay (few buttons to push).
Just a heads up to what Maya writes in post #44:
"Curse - Shepherd’s Crook
Familiar - Amatok (Blizzard)
Hellhound - Rhowan’s Crown (Elemental Storm)
Tortoise, Ishtak & Tree - any permanent/passive skills. Eg - 1 point in Mogdrogen’s Pact for Tortoise, Ishtak and Tree on Possession and Bonds of Bysmiel.
Blood of Dreeg is also an option to use, but make sure to keep it up all the time if doing that."
