Bone Splinters

Bone Splinters is your builder for this Bone Necromancer build, generating Essence so that you can keep casting Bone Spear.

It isn't too important outside of that Essence Generation, but the Acolyte's Bone Splinters upgrade also offers +8% Critical Strike Chance for four seconds if you hit the same enemy at least three times with the same cast of Bone Splinters. That'll rarely trigger against packs, but it'll give you a frequent Crit Chance boost against bosses.

Bone Spear

Bone Spear is a powerful ranged skill that deals huge damage and pierces through enemies to hit multiple targets. Since we're building around Critical Strike Chance, you should take Paranormal Bone Spear to get the extra 5% Crit Chance with this skill.

Corpse Explosion

Corpse Explosion is a very useful damage dealer when you're out of Essence and need to whittle down a mob, so we strongly recommend taking it even though it doesn't fit with the Bone theme.

Corpse Explosion deals huge damage, but it also synergises with Grim Harvest and Fueled By Death to grant you six Essence and increase your damage with a 9% multiplier for six seconds when you consume a corpse.

Corpse Tendrils

Corpse Tendrils combos with Corpse Explosion by pulling enemies in and packing them together. It'll also inflict enemies with the Slow and Vulnerable effects, allowing Corpse Explosion and your Bone skills to deal far more damage thanks to the Plagued Corpse Explosion and Evulsion skills respectively.

Bone Spirit

Bone Spirit is a powerful bomb, unleashing a spirit that charges at enemies and explodes. It deals huge damage, with a baseline of 112% skill damage and an extra 3% for each point of Essence spent when casting Bone Spirit.

The downside here is that Bone Spirit consumes all of your remaining Essence, meaning you'll need to rely on Bone Splinters and Corpse Explosion to quickly get yourself back in the game. Use Bone Spirit when a boss or elite charges in to take a large chunk out of their health bar.

Bone Storm

Bone Storm is your ultimate, unleashing a powerful storm around your character that deals huge damage for 10 seconds.

The really powerful effects come from the upgrades, though, with Prime Bone Storm and Supreme Bone Storm offering +15% Damage Reduction and +20% Critical Strike Chance while your ultimate is active.

If you're unsure how to use these skills effectively, follow the attack pattern below:

  1. If you have low Essence, use Bone Splinters or Corpse Explosion as generators.
  2. Spend Essence to use Bone Spear.
  3. Use Corpse Tendrils to pull enemies together when you're out of Essence, and then spam Corpse Explosion to quickly generate more Essence.
  4. Use Bone Spirit as a bomb when an elite or boss enters the fight.
  5. Use Bone Storm whenever you can, but especially when those elites or bosses appear.

Diablo 4 Bone Spear Necromancer build: Best Minions

The Necromancer has access to the unique Book of the Dead class mechanic, which allows them to raise three kinds of Minions: Warriors, Mages, and a Golem.

You might notice above, though, that we've opted not to use either the Raise Skeletons or Raise Golem skills, so we'd recommend sacrificing your Minions to get useful passives instead.

Below, you'll find the exact options we'd recommend choosing with your Book of the Dead for this Diablo 4 Bone Necromancer build:

  • Skeletal Warriors: Sacrifice Skeletal Skirmishers - Your Critical Strike Chance is increased by 5%, but you can no longer raise Skeletal Warriors.
  • Skeletal Mages: Sacrifice Cold Mages - You deal 15% increased damage to Vulnerable enemies, but you can no longer raise Skeletal Mages.
  • Golem: Sacrifice Iron Golem - You deal 30% increased Critical Strike Damage, but you lose the ability to summon a Golem.

Of course, this comes with a pretty big issue - you lose all of your Minions, meaning you no longer have a meatshield and will struggle when all of the damage focuses on you. In a group, you should be fine and the passives on offer here are a huge boon to the build, but be aware that you might struggle to survive in solo content.

With that in mind, definitely consider keeping at least the Skeletal Warriors and Mages if you're struggling. You will lose some Critical Strike Chance and extra Vulnerable damage, which is important for the build, but you will also find combat much easier.

If you do this, you should move skill points from Stand Alone and Memento Mori into Skeletal Warrior Mastery and Skeletal Mage Mastery. Ultimately, this is down to personal preference, and the build can still work either way.

Diablo 4 Bone Spear Necromancer build: Best Aspects

As you complete Side Dungeons or get Legendary drops in Diablo 4, you'll gain Aspects. These are Legendary powers that grant new, powerful effects when equipped, and they are crucial to making your build excel.

Below, you'll find the Aspects that we'd recommend using for this Diablo 4 Bone Necromancer build:

  • Deathless Visage (Unique Helmet - random drop): Bone Spear leaves behind echoes as it travels that explode, dealing extra damage.
  • Aspect of Shielding Storm (Legendary - random drop): Each time that Bone Storm damages an enemy, gain a Barrier equal to 2-5% of your Base Life for 10 seconds.
  • Aspect of Serration (Legendary - random drop): The Ossified Essence Key Passive also increases the Critical Strike Damage of your Bone skills by 1% per Essence above 50, up to +30-40%.
  • Aspect of Disobedience (Halls of the Damned - Kehjistan): You gain x0.25-0.5% increased Armor for 4 seconds when you deal any form of damage, stacking up to x25-50%.
  • Wind Striker Aspect (Shivta Ruins - Kehjistan): Critical Strikes grant +8-16% Movement Speed for 1 second, up to 6 seconds.
  • Splintering Aspect (Campaign Reward - Dry Steppes): Bone Spear's primary attack makes enemies hit beyond the first Vulnerable for 1.5-2.5 seconds. Bone Shards from Bone Spear deal 50-100% bonus damage to Vulnerable enemies and pierce them.
  • Aspect of Grasping Veins (Corrupted Grotto - Kehjistan): Gain +10-20% increased Critical Strike Chance for 6 seconds when you cast Corpse Tendrils. You deal x30-60% bonus Critical Strike Damage to enemies damaged by Corpse Tendrils.
  • Smiting Aspect (Legendary Amulet - random drop): You have x10-20% increased Critical Strike Chance against Injured enemies. While you are Healthy, you gain x20-40% increased Crowd Control Duration.
  • Aspect of the Umbral (Champion's Demise - Dry Steppes): Restore 1-4 of your Primary Resource when you Crowd Control an enemy.
  • Aspect of Torment (Black Asylum - Fractured Peaks): Critical Strikes with Bone Skills increase your Essence Regeneration by x20-30% for 4 seconds.

Diablo 4 Bone Spear Necromancer build: Best Stats

While hunting for Legendary Gear with the above Aspects, you also need to consider the Affixes that you get. Affixes are the various random stat rolls that you get on Gear, so it might take a while to find the rolls you really need.

Below, you'll find the Affixes that you should hunt for with this Diablo 4 Bone Necromancer build:

  • Critical Strike Chance
  • Critical Strike Damage
  • Intelligence (increases Skill damage for the Necromancer)
  • Willpower (increases Essence Regeneration)
  • Dexterity (increases Critical Strike Chance)

If you have a piece of Gear that you really like but the Affixes don't fit, head to the Occultist and Enchant the item to replace one of the Affixes.

Diablo 4 Bone Spear Necromancer build: Best Gems

Gear also often comes with Sockets, into which you can place Gems for more passive bonuses. Gems have different effects depending on whether they are placed into Weapons, Armor, or Jewelry.

In Weapons, you should use Emeralds to get increased Critical Strike Damage against Vulnerable enemies. Corpse Tendril and the Splintering Aspect will both make enemies Vulnerable, and then you can take advantage of the high Critical Strike Chance that you should have with this build for even more damage.

In Armor, we'd recommend using Rubies to get more Maximum Life. The Necromancer doesn't have high survivability, so any increases to Maximum Life are highly important for those Capstone and Nightmare Dungeons coming when you reach the endgame.

For Jewelry, we'd usually recommend using Skulls to boost your Armor stat. However, Season 1's new Malignant Hearts must be placed into Infested Sockets, which can only appear on Jewelry items, so we'd recommend skipping any Gems in your Rings and Amulets for the duration of this Season.

Diablo 4 Bone Spear Necromancer build: Best Malignant Hearts

Malignant Hearts are the major new mechanic in Diablo 4 Season 1, introduing powerful bonuses that you can earn by placing this new item into Infested Jewelry Sockets. Malignant Hearts offer a significant power boost for any class, and they're key to maximising the strength of the Bone Spear Necromancer throughout Season 1.

Below, we'll list the best Malignant Hearts for the Bone Spear Necromancer:

  • The Sacrilegious: Walking near a Corpse automatically activates an equipped Corpse Skill every second, dealing 40-30% reduced damage.
  • Tempting Fate: You gain 40-60% Critical Strike Damage but your Non-Critical Strikes deal 20-15% less damage.
  • Revenge: 10-20% of incoming damage is instead suppressed. When you use a Defensive, Subterfuge, or a Macabre skill, all suppressed damage is amplified by 250% and explodes, dealing up to 1360-2040 Fire damage to nearby enemies.
