Bone Spear Endgame Necromancer Build for Diablo 4 (Season 3)

Build Introduction

Bone Spear Necromancer is one of the smoothest builds to level a Necromancer with; It performs just as well in the endgame content by providing high critical hits with Bone Spear in combination with an insane amount of corpses being generated. We can easily regain our Essence at the same time as we are dealing respectable damage using Corpse Explosion, making the Bone Spear Necromancer a very consistent and reliable build. A very important note here is that the Blighted Corpse Explosion deals damage twice per second helping us generate an insane amount of corpses via Hewed Flesh, which is how we sustain the build.

In the endgame we will gain access to more legendary powers that takes this build to a whole new level. Since our biggest source of damage comes from Bone Spear, we can provide legendary powers to help sustain more or less only casting the Bone Spears!

Besides being reliable and consistent, this build guarantees the Vulnerable effect on enemies, making it a great option for group play. On top of this, you’re able to chose whether or not you want to run with Melee Skeletons, as having minions tank enemies for you and/or your friends can be very helpful. You also have the option to simply sacrifice them and use Bone Storm to provide more damage output.

You are able to level with this build, however we would strongly recommend checking out the Necromancer Leveling guide for the smoothest experience going through the campaign before switching to this build.

Patch 1.3.0

• No direct changes but the removal of Abbatoir of Zir has made this build the expected best Necromancer build for the season!

Seneschal Construct Companion Powers

The Season 3 theme introduces a Seneschal Construct Companion that can deal damage or provide support to complement your character. Equip the Seneschal with two Governing Stones to activate their abilities, and then link them to three Tuning Stones each to augment the abilities. There are 12 different Governing Stones and 27 different Tuning Stones that can be found in Vaults scattered across Sanctuary. Fuse together duplicate stones to level them up, increasing the potency of Governing Stones or adding augments to Tuning Stones.

Listed below are the recommended Governing Stones and their linked Tuning Stones for the Blood Lance Necromancer, ranked by importance. The Governing stones you want to use for this build will be Lightning Bolt, and Tempest.

• Resource Support: The Construct will generate Essence for us on a consistent basis.
• Evernight: Grants +4 to all skills for a very short duration. You will want this on both skills the Construct uses to optimize uptime to increase damage output.
• Safeguard: Provides extra Damage Reduction.
• Duration: Extends the duration of the skill which is best combined with Lightning Bolt and the use of both Resource and Safeguard.
• Breaking: Instantly destroys Barrier effects and makes enemies vulnerable.
• Arcing: Makes the ability hit 10 additional enemies. Best combined with Breaking to make the effect hit more enemies.
• Efficiency: Provides extra Critical Strike Chance.

When it comes to the active skills for the Construct, it truly does not matter for this build. Whichever ability provides the fastest or most reliable hits on enemies will the best choices for Bone Spear.

Book of the Dead

We will be sacrificing both our Mage Skeletons and our Golem. The decision to sacrifice the Melee Skeletons, however, comes down to personal preference and how their survival looks at higher endgame content. Playing in a party can impact this decision as well. Below you’ll find the details covering all aspects of how we utilize the Book of the Dead for the Bone Spear Necromancer.

• Melee Skeletons; we have two choices when it comes to the Melee skeletons:
  • If we decide to sacrifice them, we’ll want to do so with the Skirmishers, as we gain increased Critical Strike chance. We will also have to adjust our skill-points in the tree if we sacrifice them, by removing all three points from the Skeletal Warrior Mastery and taking all of the Bone Storm nodes instead for better critical strike hits as well as increased damage reduction. It’s also important to note that by removing our Reapers we also need to move our 3 points from Necrotic Carapace and place them in Rapid Ossification.
  • If we decide to keep the Skeletons, we will want to use the Reapers and have them generate corpses by hitting enemies. This combination with the build creates an absurd amount of corpses very fast which not only offers easy access to gain Essence and/or re-summon Skeletons, but also offers consistent damage output when we run out of Essence after spamming Bone Spear.
• Mage Skeletons; sacrificing the Cold Mages grants us increased damage to Vulnerable enemies. The build reliably making enemies Vulnerable makes this the best choice.
• Golem; the goal for this build is to deliver high spikes of damage in the form of Bone Spear. We want to make sure we deal Critical Strikes and also increase the Critical Strike Damage, and by sacrificing the Iron Golem we gain just that.

Paragon Board

The Paragon progression system unlocks at Level 50 and provides a vast amount of character power. On the Paragon Board, bonuses range from minor stats on Magic Nodes to more powerful Rare Glyphs and Legendary Nodes.

As you path towards Glyph Sockets and Legendary Nodes, you should prioritize Damage, Intelligence, Resistance, and Life for Normal and Magic Nodes. Glyph radius increases as you level them up. Therefore, if you cannot fulfill Additional Bonus requirements early on, skip allocating extra nodes for now. It’s also important to point out that you might not have the Glyph you want when you reach your first socket; if that is the case, simply slot in any Glyph providing any beneficial stats for you until you get the correct one.

Listed below are images of the pathing you should take along with the locations of the Glyphs and order you should choose your Paragon Boards past the initial Starting Board.

Starting Board

For the Starter Board, we will path along the right side, all of the Magic Nodes as we grab three Rare Nodes and the socket slot to get the Control Glyph. (If you’re using the end-game version of this build the Glyph should be Amplify instead). If you are able to collect enough Intelligence within radius, depending on the level of your Glyph, you should. Once done with the board, we will head on north and attach Bone Graft.

Bone Graft

Bone Graft should be rotated to have the Legendary Node easily accessible on the right-hand side. We begin the route by rushing that node and picking up both Rare and Magic Nodes, as we do a push to the top left corner moving in to the socket slot. Optimally we want the Exploit Glyph slotted in here, and only pick up extra Dexterity Nodes within radius if the Glyph level has enough within radius. This should be the first Glyph you’ll want to level up. The next step from here is to path out on the left side for our third board, Scent of Death.

Scent of Death

Scent of Death will need to be rotated so you have the Legendary Node located on the south side as we will be rushing the socket slot before we pick up all Rare and Magic Nodes, finishing the pathing with the Legendary node. The Glyph we’ll be using here is the Corporeal Glyph. Similar to previous boards, we will only be going out of our way to pick up extra attributes enabling the bonus modifier if we can, based on the Glyph level. Once done here, we will head out north for our fourth board, Flesh-Eater.

Flesh-Eater

Flesh-Eater which will be positioned so the Legendary Node is again located as far from our starting point as possible. We are going to be picking up the socket first in which we slot in the Amplify Glyph. If you’re using the end-game version of this build, the Glyph should be Sacrificial instead. Same procedure here as before, only take the extra surrounding attributes if needed and possible within the Glyph radius based on its level. Next we actually skip the Legendary Node and rush towards the remaining Rare and Magic nodes on the left while skipping the top right Nodes, as the goal is to get to the last board, Bloodbath, on the left side.

Bloodbath

Bloodbath’s only purpose here is to grab the socket. Rotate the board to match the image above. We will rush the socket and slot in the Essence Glyph. Needless to say, we are picking up the surrounding Dexterity if the Glyph level allows for it. Once this board is finished we will circle back for the remaining Rare and Magic Nodes on our fourth board. At this point, you’re either finished or you have spare attributes to pick up within radius of your Glyphs as they level up.

Mechanics and Playstyle

Mechanically, we are aiming to maintain a rotation where we deal consistent damage no matter if you have a full Essence bar or if you have just emptied it. By having a reliable source of afflicting enemies with Vulnerable, as well as multiple sources for creating Corpses, we can stay at a safe distance, dealing damage by slamming enemies with Bone Spear. When we are out of Essence, we simply spam Corpse Explosion, dealing tons of damage while also regenerating Essence to go back to hitting hard with your Bone Spear.

Playstyle-wise, we want to stay away from enemies, which is why we have Blood Mist as a back-up option. You will be forced to tank enemies as you play, and to solve that problem we will invest 5 points to Corpse Tendrils to control the damage dealt by the enemies. Outside of the defensive details, we will be spamming Bone Spear and building our Essence back up with Corpse Explosion. In the higher endgame, we will be able to utilize Legendary aspect powers to sustain Bone Spear, thus even better minimizing the need to spam Corpse Explosions and allowing for even higher damage output.

Gear Choice and Stat Priority

Prioritize a higher total damage output when it comes to your weapon, as the higher it is, the better. It should be kept in mind that if you find a higher Item Power 1-Handed weapon, that it could very well be better than a 2-Handed weapon if coupled with an Off-hand or even a shield, as Shields scale your main-hand weapon by 80%!

Listed below are the affixes to prioritize on gear for Bone Spear Necromancers. Affixes for each gear slot are listed in order of importance. Bolded stats are the most important and sometimes vital for the build to function properly.

Legendary Aspects and Uniques

The Bone Spear Necromancer is all about Bone Spear and making enemies Vulnerable. Due to this, there is only one mandatory Codex Power, namely the Splintering Aspect. Listed below are the recommended Codex Powers and Aspects found on Legendary Items that are important for the Bone Spear Necromancer build, alongside optional ones in case you have decided to run Skeletal Warriors.

Aspects from the Codex of Power can be used if you cannot find the proper Legendary drops, but they have weaker effects. Extract Aspects from the lower level Legendary Items and imprint them onto better Rare Items with preferred stats.

Most important powers for this build is the Splintering Aspect and Aspect of Disobedience. Make sure you have those, and all others are just additional bonuses as you progress your character.

Gear Slot	Aspect Name	Aspect Power
Helm	Protecting Aspect	When hit while not Healthy, a magical bubble is summoned around you for 3-5 seconds. While standing in the bubble players are Immune. Can only occur once every 90 seconds.
Amulet (50% scaling)	Aspect of Grasping Veins	Gain 10-20% increased Critical Strike Chance for 6 seconds when you cast Corpse Tendrils. You deal 30-60% bonus Critical Strike Damage to enemies damaged by Corpse Tendrils.
Chest	Aspect of Disobedience	You gain 0.25-0.5% increase Armor for 4 seconds when you deal any form of damage, stacking up to 25-50%.
Boots	Wind Striker Aspect	Critical Strikes grant 8-16% Movement Speed for 1 second, up to 6 seconds.
Gloves	Splintering Aspect	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.
Pants	Aspect of Might	Basic Skills grant 20% Damage Reduction for 2-6 seconds.
2H Sword (100% Scaling)	Aspect of Serration	The Ossified Essence Key Passive also increases the Critical Strike Damage of your Bone Skills by 1% per Essence, up to 30-40%.
Ring	Accelerating Aspect	Critical Strikes with Core Skills increase your Attack Speed by 15-25% for 3 seconds.
Ring	Aspect of the Umbral	Restore 1-4 of your Primary Resource when you Crowd Control an enemy.

Unique Items

The Deathless Visage is an incredible Unique item making our Bone Spear leave behind echoes as it travels. These echoes explode, dealing massive amounts of damage in their wake. Most importantly, it provides Critical Strike Damage for your Bone Skills & increased Maximum Essence. If you do not have access to this Unique item, you can simply add the Legendary effect listed above.

Getting your hands on the Ring of the Sacrilegious Soul is amazing and would mainly be used for this builds end-game version seen below and it replaces the Osseous Gale Aspect aspect.

End-Game Notes

Once you find the Aspect of Exposed Flesh (this will replace your Aspect of the Umbral) and have a proper pair of gloves you’ll want to make sure you reach 50% increased Critical Strike Chance in your tooltip, as the remaining 50% is coming from your Aspect of Grasping Veins and Supreme Bone Storm. This allows for absurd end-game damage output and the gear allows you to more or less never cast anything but Bone Spear. To reach this state of the build you’ll need proper gearing as displayed in this guide. You’ll also change your Accelerating Aspect to Osseous Gale Aspect as well as Aspect of Might for Aspect of Shielding Storm.

When it comes to the current seasonal vampiric powers we’ll be replacing both minion related powers with Anticipation and Undying.

The important part here besides the small Aspect changes is that you’re able to change your skill tree around a bit for better optimization, at which point we strongly recommend changing it to the tree table shown below. Our Control Glyph in the first Paragon Board is also changed to the Amplify Glyph. Should you find yourself struggling with sustaining your Essence, it means you are simply not geared enough to handle it and should revert back to the original plan this guide is showing.

Priority Skills	Cluster
Bone Splinters, Enhanced Bone Splinters	Basic Skill
Bone Spear Level 5, Enhanced Bone Spear, Paranormal Bone Spear, Hewed Flesh Level 3, Unliving Energy Level 3, Imperfectly Balanced Level 3	Core Skill
Blood Mist	Corpse & Macabre Skill
Decrepify, Enhanced Decrepify, Abhorrent Decrepify, Amplify Damage Level 3, Death’s Reach Level 3, Death’s Embrace Level 3	Summoning Skill
Corpse Tendrils, Enhanced Corpse Tendrils, Serration Level 3, Compound Fracture Level 3, Evulsion Level 3, Rapid Ossification Level 3	Curse Skill
Inspiring Leader Level 3, Stand Alone Level 3, Memento Mori Level 3, Bone Storm, Prime Bone Storm, Supreme Bone Storm	Ultimate Skill
Ossified Essence	Capstone Skill

The Book of the Dead remains the same with all 3 minions sacrificed.

Gems

Listed below are the best Gems to socket into gear for each slot type.

• Weapon: Royal Emerald for +#% Increased critical strike damage to Vulnerable enemies.
• Armor: Royal Ruby for +#% Maximum Life.
• Jewelry: Royal Skull to increase our armor.

Elixirs and Health Potions

To gain an edge in your adventures, head to the Alchemist in any major town, and craft Elixirs that enhance your stats and experience gain for 30 minutes. Remember to gather the necessary crafting materials by foraging plants. Select an Elixir that provides the resistance you need most, or try the Assault Elixir to boost your Attack Speed.

Return to the Alchemist again when you reach Level 20, 30, 45, 60, 70, 80 and 90, to upgrade your potion. The extra healing is essential to survival.
