Diablo 4 Necromancer BuildBone Spirit

This build takes full advantage of the Blood Artisan’s Cuirass to pump out massive Bone Spirits for free. Normally Bone Spirit consumes all of your essence on cast to do bonus damage, but with this Unique chest we get a free Bone Spirit for every 5 Blood Orbs we pick up, and it does bonus damage based on our current Essence without consuming any. This means as long as we are full on Essence and have a steady supply of Blood Orbs we can constantly cast free and fully ramped Bone Spirits, allowing us to do extremely high damage.

Corpse Tendrils is a very important part of this build as it groups enemies so we can easily AOE them down and also procs our Aspect of Grasping Vines, giving us massive Crit Chance and Crit Damage. The Corpse Tendrils also has a chance to spawn Blood Orbs for each enemy hit, which is perfect for making use of our Blood Artisan’s Cuirass.

Corpse Explosion is in the build mostly just as a way to steadily eat Corpses, which procs many of our damage buffs while also spawning Blood Orbs.

This build pumps out serious damage when there are many enemies, but it can struggle against fewer targets as it struggles to generate enough Blood Orbs. When there are few enemies we rely heavily on our Hemorrhage to get Blood Orbs, and it's very important to track the count on Blood Artisan’s Cuirass, and only spawn Spirits when you have Corpse Tendrils and Vulnerable up.
