Build Guide
Main idea: Sacrificing (NUM-locking Devour and Mages) in favour of endless corpses AND essence -> this means the same for corpselances due to our Set bonus.
While clearing T13 fast (and I mean really fast) and collecting the much needed gold, especially at start of the season with eazy obtainable gear due to the starter set.
While you are constantly creating (NUM-lock Mages - Gift of Death) and instantly killing them again (Devour-Ruthless), you are gaining more Essence than you lose [instead of 1 Mage you cast every time 2 at once (Circle of Nailuj) and this means 2x corpses because the Gift of Death rune PLUS 2x 10 Essence because of the Ruthless rune].
Now we killing trash mobs without much effort. But now comes Simulacrum and Haunted Visions combined with In-Geom into play. With the 50% increased duration of Simulacrum and our CDR and In-Geom and our Passive: Blood is Power, we have a perma-Simulacrum. You think why this is important? Yeah, we have a direct impact on DMG due to Reilena´s, PLUS you generate permanently 4 corpses + 40 Essence back, because your Simulacrum casts also 2 additive Mages, which disappear immediately and provide INSANE number of corpses and this means even more DMG!
With Bone Armor and the cold rune provides us procs on Lost Time, so we move even faster.
You think its useless? Because Goldwrap? - Well you might be right - most of the time - but while starting a rift, especially with low gear, when you do not have picked up any gold, you will feel much more comfortable jumping into a pack of mobs, fire your Bone Armor and leave it again with BloodRush - you anyways have 2 charges (Metabolism). It grants you a bit of toughness when you are unable to kill mobs and not having picked up gold recently plus it increases your speed plus all doors getting smashed by Bone Armor also.
At very large groups / Elite Packs - you manually cast corpselance - everything disappears on screen
This build is valid solo and into groups, your damage is soon high enough. Also valid for Bounties.
Usually you just Blood Rush to skip walls or reposition in bad maps. In open maps your movespeed is as fast as BloodRushing.
Tipp: you can switch Dark Reaping passive out for Life From Death. If you prefer health globes instead of direct heal + essence.
Its my first build. If i did not mention everything, just ask me and I will respond/edit this.
You pretty much have to switch Dark Reaping for, anything else, really. It won't work with In-Geom. But it's a cool build idea.
