Build Guide
Rotation is fairly simple. When first approaching enemies use bone armor and then begin attacking with grim scythe minimum of three swings to stack curses. Use bone armor when ever the CD is up to max out your stacks and deal damage. Use corpse Lance to tear higher hp enemies down quicker and as you have corpses on the ground. Use blood rush to get out of trouble or skip trash. Land of the dead and Army of the dead are usually reserved for elites or a death prevention method if getting overrun by mobs.
Any stat priorities for equipment?
Wouldn't Lost Time be a better Phylactery, being that you're using cold abilities, as opposed to Iron Rose that increases Blood Siphon which appears to be missing from this build? Or perhaps a Lidless Wall (+cold% wouldn't be bad, and even +Poison% would seem to be more effective than Iron Rose)?
