    The Bone Spear Necromancer remains one of the most powerful endgame builds in Diablo 4, thanks to its high burst damage, excellent crowd control, and devastating crit scaling. Whether you’re farming Nightmare Dungeons, clearing Helltides, or taking on endgame bosses, this build offers a consistent mix of single-target and AoE destruction.

    With the changes in Patch 2.1.0 and the Season of Witchcraft, Bone Spear has become even stronger, especially with the addition of Indira’s Memory, which converts Bone Spear into a Blood Skill while triggering additional projectiles. This guide will break down the best skills, passives, gear, Paragon Board choices, and Witchcraft powers to make your Bone Spear Necromancer unstoppable.


    Why Bone Spear?

    Best Bone Spear Necromancer Skills

    Core Skills & Upgrades

    Bone Prison (5/5) Ghastly Bone Prison
    Corpse Tendrils (1/5) Plagued Corpse Tendrils
    Soulrift (1/5) Prime Soulrift

    Book of the Dead – Minion Sacrifices

    Since Bone Spear benefits from high crit and vulnerability damage, we’ll sacrifice all minions for massive bonuses:

    Skirmishers (Sacrificed): Increases crit chance.
    Cold Mages (Sacrificed): Boosts Essence Regeneration.
    Iron Golem (Sacrificed): Provides bonus crit damage.


    How to Play This Build

    1. Reap an enemy to generate a Corpse.
    2. Use Corpse Tendrils to pull enemies into a group.
    3. Cast Bone Prison to lock them in place.
    4. Drop a Blight on the grouped enemies to apply Vulnerability.
    5. Unleash Bone Spear for massive piercing damage.
    6. Use Soulrift before big fights to gain bonus damage.

    This rotation ensures that enemies stay locked down, while Bone Spear shreds through them with maximum crit scaling.


    Best Passives for Bone Spear Necromancer

    Passive Effect
    Hewed Flesh Increases Corpse generation.
    Imperfectly Balanced Boosts Bone Spear damage but increases cost.
    Titan’s Fall (1/3) Increases Overpower damage.
    Coalesced Blood Boosts Blood Skill effectiveness (once Indira’s Memory is equipped).
