Bone Spirit – Necromancer Build for Diablo 4 (Season 11)

Build Introduction

Bone Spirit is the iconic build for Pit of Artificers or The Tower pushing. Fulfilling extreme gear requirements just to barely function and strict skill rotation are rewarded with highest damage bursts known to Necromancer. It is one of very few builds that use Melted Heart of Selig to its full potential.

Gear, Gems, Elixirs and Stats

The following sections cover the important systems that are essential to improving the power of your character in the endgame of Diablo 4.

Legendary Aspects

Each aspect is listed with its matching gear slot. Do your best to keep each aspect in the assigned slot. Aspects placement is planned with potential Unique and Mythic Unique gear upgrades in mind for easiest and cheapest transition. Obol gambling is a great way to try to obtain specific slot Legendary Aspects and even Uniques early.

Gear Slot	Gems	Aspect / Unique	Legendary Aspect / Unique Power

Affixes and Tempering Priority

• Affixes on gear are sorted in priority descending order.
• Bolded affixes are the most important targets for Masterworking upgrade. If multiple affixes marked – any selected is acceptable for case by case gear.
• Affixes marked by multiple “*” – indicate desirability of obtaining them as Greater Affix originally or with lucky Tempering.

Be sure to check our Tempering and Masterworking guides for more details about these topics.

There are hard stats requirements to function properly in descending priority that override any other suggestion or reject gear swap if not met or get closer to the target values:

• 100% Critical Strike Chance.
• Cooldown Reduction effects for Bone Spirit pushing it below an 8 seconds cooldown.
• Casting Macabre Skills Restores +X Primary Resource for Ossified Essence as high as possible.

Ancestral and Mythic Uniques

See below for information on useful Uniques and how to integrate them into this build:

Path of Trag’Oul [Required]

Mandatory build-defining unique. High amount of Bone Splinters from the aspect provide Essence pool for Bone Spirit and Ossified Essence. Bone Prison Cooldown is vital for uninterrupted skills rotation and ranks to Bone Skills is a bonus at this point.

Obtained from Grigoire Lair Boss.

Blood Moon Breeches [Required]

Extremely potent gear piece, contributing significant damage multiplier and doubled Critical Strike Chance amount needed to reach required 100%. Straightforward Pants slot replacement.

Obtained from Duriel or Andariel Lair Bosses.

Heir of Perdition [Best in Slot]

Best in slot Mythic Unique Helmet for most Necromancer builds. Provides significant damage multiplier, massive amount of Critical Strike Chance, Lucky Hit to improve Cooldown Reduction engine and extra mobility. Requires to switch from Aspect of the Cursed Aura to Igni Wat runeword to maintain auto-curse, see here how. Unless Sanctified Aspect of the Cursed Aura obtained and another one is applied to the Boots.

If you are interested in target farming Mythic Uniques, check out our How to Farm Mythic Uniques guide.

Shroud of False Death [Best in Slot]

Best in slot Mythic Unique Chest for most Necromancer builds. It provides significant effective damage multiplier and utility improvements all across the board, via +1 All Passives bonus. Sizeable All Stats affix makes Rare Paragon Node bonus requirements easier to fulfill. Straightforward Chest slot replacement.

If you are interested in target farming Mythic Uniques, check out our How to Farm Mythic Uniques guide.

Melted Heart of Selig [Best in Slot]

Best in slot Mythic Unique Amulet for Bone Spirit . It provides massive pool of essence for Bone Spirit itself and Ossified Essence. Additionally it gives outstanding resource management and survivability by making essence to act as a barrier. Losing Sacrificial Aspect may put you below 100% Critical Strike Chance, so it has to be moved over Aspect of Serration or Aspect of the Damned slot.

Mercenaries

During the “Vessel of Hatred” campaign, you will unlock Mercenaries to assist you. While you can choose freely early on, we recommend Raheir as your main merc:

• Ground Slam
• Raheir’s Aegis
• Bastion
• Inspiration

For the reinforcement, stick with Aldkin and his Flame Surge to trigger Abhorrent Decrepify when any Skill used

• Flame Surge

Build Mechanics

This build is designed to isolate enemy packs using Path of Trag’Oul‘s effect with Bone Prison. This is done to boost Essence pool and allows you to target anything inside with Bone Spirit shotguns. Since all main skills of our rotation have cooldowns, the main focus of the build is dedicated to solving cooldown reduction and reset.

Rotation and Playstyle

1. If a is Corpse available, Corpse Tendrils on the Corpse and wait until mobs are pulled in.
2. Isolate as many enemies with Bone Prison as possible and throw Blight inside.
3. If possible, reposition yourself closer to Bone Prison with few steps or Evade.
4. Activate Soulrift to apply Vulnerable, damage multiplier and extra essence gain.
5. Keep casting Bone Spirit at close distance from Bone Prison as Essence and cooldown allow, Bone Prison stands and there are plenty of targets inside.
6. Repeat to refresh Bone Prison and/or pull in more target.
7. If stuck in an enemy pack, crowd-controlled, or heavily poisoned, use Blood Mist to become Unstoppable and remove all negative effects. It can be interrupted early by another click.

Bone Spirit Cooldown and Essence Management

• Active Cooldown Reduction Engine
• Affix: Cooldown Reduction
• Enhanced Bone Spirit sets goals for 100% Critical Chance and Bone Spirit cooldown to be under 8 seconds.
• Rapid Ossification provides extra few seconds of Bone Spirit cooldown on its own cast per 100 Essence spent, which sets target of maximum Essence gain after each cast via:
  • Necromancer Invigoration Casting Macabre Skills Restores +# Primary Resource [23 – 47]
  • Affix: Resource Generation
  • Affix / Paragon: Maximum Resource
  • Affix: Lucky Hit: Up to a 15% Chance to Restore +# Primary Resource

Cooldown Reduction Engine

This build heavily relies on the ability to reduce the cooldown of certain skills in your rotation. Cooldown Reduction engine is a set of abilities, upgrades and buffs that reduce active cooldowns by fulfilling certain conditions. In this particular case it is based on Lucky Hit against cursed by Abhorrent Decrepify, which is automatically applied by Aspect of the Cursed Aura or by the Runewords Igni Wat.

List and properties of Lucky Hit triggers used:

• Aldkin mercenary Flame Surge (damage over time, AoE)
• Blight, Soulrift (damage over time, AoE, high Lucky Hit Chance)
• Corpse Tendrils (multi-target attack)
• Bone Splinters from Path of Trag’Oul Bone Prison
• Bone Spirit (AoE, multi-projectile, high Lucky Hit Chance)

Which Elixirs Should You Use?

Visit the Alchemist and craft an Elixir of Precision II, if you lack Critical Strike Chance, or Elixir of Resourcefulness II to increase damage from Ossified Essence. 

Recommended incenses are Reddamine Buzz, Soothing Spices, Sage’s Whisper.

We have much less Health Potions now, so make sure to keep them upgraded!
