Diablo 4 Bone Spear Necromancer Build Guide

Intro

The Bone Spear Necromancer is a devastating build capable of annihilating hordes of enemies with a single, well-placed Bone Spear. Renowned for its immense damage output and excellent survivability, this build thrives in both midgame and endgame content. However, it comes with some drawbacks, such as low mobility and a heavy reliance on corpses. This guide provides a comprehensive overview, covering gameplay mechanics, skills, gear, and glyph recommendations to maximize your Necromancer’s potential.

Diablo 4 Bone Spear Necromancer Gameplay

This build centers on Bone Spear, a high-damage skill that excels in clearing both mobs and bosses. It is further enhanced by Corpse Explosion, which deals consistent AoE damage and generates corpses to sustain your abilities.

Key Mechanics:

• Corpse Explosion Synergy: The Blighted Corpse Explosion synergizes with Hewed Flesh to generate a large number of corpses, ensuring steady resource generation and damage output.
• Vulnerable Effect: Bone Spear applies the Vulnerable status, amplifying damage for both you and your allies.
• Sacrificial Minions: By sacrificing all minions through the Book of the Dead, you gain significant bonuses, enhancing Critical Strike chance, damage, and Essence generation.
• Late-Game Adaptations: As you progress, Legendary Aspects enable near-continuous Bone Spear usage, boosting the build’s overall effectiveness.

This build is particularly potent in Nightmare Dungeons, allowing you to take on enemies 15–20 levels above your own, provided you manage corpses and cooldowns effectively.
