This is a pretty fun to play ranged sniping Necro build focusing on spamming Bone Spear with the Pestilence set.

You'll automatically consume corpses around you which will proc Corpse Lances and give you essence and health and most importantly gives you the 3000% damage buff to Bone Lance.

I did a GR60 in ~11 minutes to test this build with mostly below average rolls on all items, ~730 Paragon, 2 ancients, and level ~50 gems (~1 million sheet dps in town, ~12 million toughness and ~1.5 million regen), so higher Greater Rifts should definitely be possible with better items and gems and most importantly actually trying more than a single GR60

[will test more in the next days and try to get a video up]

Though I guess it will only go to around ~70 like most Non-Inarius builds right now it seems

Build Guide

You can switch the weapon in the cube and hand if you want to use an offhand of your choice (Lidless Wall probably).

When entering a rift, first of all activate the golem for 8 corpses to consume to get 10+ stacks of the bone spear buff (since golem also generates +1 corpse per second passively). Then as usual try to get your Bone armor stacks up ASAP and cast Decrepify on any new enemies you spot, and make sure to always have at least 1 enemy with a curse up for the defense buff from the belt.

You'll constantly consume corpses around you with the Devour aura, fueling your essence, healing you, procing health globes and doing damage through the 2 piece bonus corpse lances flying around.

You should never really run out of corpses with how much damage Bone Spear does even with it costing 40 essence (I never dipped below ~80% in the GR60) but you can use command golem to generate 8 corpses for fuel in a pinch too. While running around the golem will spawn corpses every second near you which will get auto-devoured too, so you'll costantly have 75+ stacks of the Bone Spear buff and never run out unless you die.

But then you respawn, hit bone armor and golem and you're up 10+ stacks again within a second.

Try to keep some corpses around when the Rift Guardian spawns in case it's a really shitty one it could be you'll get essence problems there while holding left mouse button to bone spear spam. You could also go for the corpse generation on the teleport skill if you want but I prefer the 2 teleports.
