Lots of numbers in every way possible. This build is based around constant, continuous damage. The main bread and butter of the build is Dark Curse and Bone Spear -- both providing substantial direct and DoT Damage. Bone Armor is used in this case to give a burst of damage through debuffing the enemies, and Corpse Lance comes more into play when fighting bosses.
I've been playing around with a poison Corpse Explosion variant, but the dot ticks are slow and don't stack with other corpses, which would be OP as hell, but still a detriment to the build with the goal being more ticks, not less.
