Book of the Dead

    • Sacrificing Cold Mages increases your damage against Vulnerable enemies by 15%

How to Use Bone Spear Necromancer Build in Diablo 4 Season 1

The Bone Spear Necromancer build is built entirely around making the Bone Spear Core Skill as strong as possible. It relies on having high Crit Damage and Crit Chance, as well as increased damage to Vulnerable targets.

When built correctly, it is one of the most powerful Necromancer builds for leveling, and can also carry you through to the endgame.

Diablo 4 Necromancer Legendary Aspects

The general idea is to begin every combat encounter by activating the Bone Spear Skill, dealing massive damage to single targets to take them down easily.

This will leave Corpses on the field for you to activate using your Corspe Explosion and Corpse Tendrils Skills. Corpse Tendrils will pull in all enemies within a certain radius, allowing you to spam Bone Spear and take out a high density of clumped-up enemies.

When you need to recharge some of your Essence, the Darkness damage over time from Blighted Corpse Explosion is an effective way of finishing off any remaining stragglers.
