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 SpearBone 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 ExplosionCorpse Explosion, making the Bone Spear Necromancer a very consistent and reliable build. A very important note here is that the Blighted Corpse ExplosionBlighted Corpse Explosion deals damage twice per second helping us generate an insane amount of corpses via Hewed FleshHewed 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 SpearBone 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.

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.

Skill Bar and Skill Tree Points

Suggested Skill Bar
Bone Spear Bone Spear Blood Mist Blood Mist Corpse Explosion Corpse Explosion Corpse Tendrils Corpse Tendrils Bone Storm Bone Storm Decrepify Decrepify

Follow the points allocated in the Skill Tree above for the complete 58-point build. The additional 10 skill points are completed using the Renown system.

Book of the Dead

We will be sacrificing all our minions. 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; Skirmishers will be the choice here for the added critical strike chance.
  • 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; Iron is sacrificed for extra critical strike damage.

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. Note that each Rare Glyph’s information and radius listed below is for the Level 21 version.

1. 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 ControlControl Glyph. (If you’re using the end-game version of this build the Glyph should be AmplifyAmplify 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.

2. 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 ExploitExploit 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.

3. 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 CorporealCorporeal 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.

4. 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 AmplifyAmplify Glyph. If you’re using the end-game version of this build, the Glyph should be SacrificialSacrificial 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.

5. 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 EssenceEssence 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.

Rotation and Playstyle

The build features a very straight forward play-style, you are essentially always casting Bone SpearBone Spear as your main source of damage. To help boost your damage and efficiency we want keep up our DecrepifyDecrepify curse as it will lower the cooldown of our Bone StormBone Storm. Besides the obvious we will be using Blood MistBlood Mist as a panic button and Corpse TendrilsCorpse Tendrils is utilized to group enemies together for easier bursting of enemy packs. The Corpse ExplosionCorpse Explosion is used when you run out of Essence and the shadow damage pool it leaves on the ground also makes you move faster when it hits an enemy!

Uniques and Uber Uniques

Below you will find information on Uniques and Uber Uniques that are useful for this build. Moreover, if you are interested in target farming Uber Uniques, check out our How to Farm Uber Uniques guide.

Uniques

Listed below are the recommended and optional Unique Items for this build. This build thrives of the legendary aspect powers so we would prefer not to involve any uniques to have the build function the best. This doesn’t mean you can’t play around with some changes and test it out yourself though!

  • Ring of the Sacrilegious SoulRing of the Sacrilegious Soul is a great tool to automate your corpse skills but comes at the cost of the Conceited aspect making you deal less damage to gain a bit of quality of life.

Season 4: Loot Reborn

The following list details the changes in the Season 4 Update (Patch 1.4.0) that may pertain to the Summoner Necromancer build. Check the Changelog for all the other guide updates. As you can see only 1 change affected the build directly and its a good one!

  • There was no notable changes outside of the removal of the Movement Speed penalty when using Blood MistBlood Mist which we only use as a panic button in this build.

Advanced Information

Below, you will find every additional piece of information you need to know for a more in-depth look at this build.

Build Mechanics

The build functions with the combination of regaining essence via corpse consumption and heavily reducing the cost of our abilities. Thanks to our skill-tree, we gain big bonuses when having a large Essence pool when we use our Bone SpearBone Spear making it vital to sustain it which our gear modifiers will help achieve. Besides this we are consistently going to re-apply Bone StormBone Storm via Lidless WallLidless Wall when we move from pack to pack clearing enemies. These Bone Storms also generate a barrier for personal defenses.

Before you reach super optimized gearing the corpse skills will help maintain the play-style and efficiency.

Defenses

Through the consistent application of Bone Storms via our unique shield, this build will have very high up-time with Barrier for protection. Outside of that, the build dishes out a crazy amount of damage with lucky hit modifiers allowing you to crowd control enemy packs.

Offenses

With a heavy focus on critical hits, the Bone Spears cover large areas with instant damage application. This is combined with Corpse TendrilsCorpse Tendrils to group up enemies to demolish them in a swift move by throwing your Bone Spears right after!
