Build Overview

Astral Projection Bone Spirit has received a massive buff coming into season 14 with the bug fix to Lidless Wall. This in combination with Aspect of Interdiction and Aspect of Redirected Force allows the build to sidestep all the nerfs to Overpower to remain a top tier pick thanks to its insane clear speeds, great damage, and high survivability.

The offensive stat priority should be an as equal distribution as possible between Physical Damage Multiplier, Critical Strike Damage multiplier, and Vulnerable Damage multiplier. Make sure to grab one or two All Damage Multiplier to round out the gear.

The Undercrown is used in the Early Game variant until players have access to Greater Affix rolls of Essence Regeneration in their gear. Because this helmet increases the maximum number of mages by 4, you can a greatly increased bonus from Gift of Death Skeleton Mage to make up less Essence Regeneration from affixes.
At this stage, it is recommended to have at least 2 rolls of regular essence regeneration affixes in the gear.

Maximum Life is the most important stat for defense when Resolve stacking with Aspect of Shielding Bones on our Amulet and Aspect of Glynn's Anvil on our legs.

Aspect of Shielding Bones is imprinted onto our necklace using a Kullean Tuning Prism at the Horadric Cube.

An update is pending to fix an error with Charm selection. The correct charms will be listed below:

The correct Charm set to run is the Desecration set. The ideal stat to look for is +3 ranks into Bone/ Core/Macabre skills.

Ranks to Bone Skills will increase the bonus from Roll the Bones Bone Storm for more Critical Strike Chance and Attack Speed. This should be the first choice.
Ranks to Core Skills will also boost your Gift of Death Skeleton Mage for more Essence Generation bonus.
Ranks to Macabre Skills adds no additional bonus outside ranks to Bone Spirit.

The correct Seal choice is any 6 Charm Slot Seal.

Blood Lance is used on the build as a quick way to spend an Overpower stack to maintain the buff from Dominate as you only gain the damage after gaining a stack. So being at full stacks all the time will block the additional multiplicative damage bonus from the glyph.

Inexorable Reaper Sever is used as the main mobility tool for the build

Gift of Death Skeleton Mage is used for the multiplicative bonus to Essence Regeneration.

Frequently Asked Questions

How To Scale Damage

Maximum Essence:

Astral Projection Bone Spirit has a unique property which allows it to scale with Maximum Essence through the Core Skill Bone Spirit upgrade. Due to this, Maximum Essence becomes a powerful affix that can roll on your Helmet, Chest, and Amulet. However, the more Maximum Essence players gain, the more Essence Regeneration is needed to make use of it.

Because of this, The Undercrown unique charm can be used when players attain multiple sources of Maximum Essence on their gear to help generate extra Essence through the Gift of Death Skeleton Mage upgrade on the skill tree.

Damage Multiplier Affixes:

Season 13 has completely reworked the damage formula, with multiplicative damage bonuses now being added to gear slots. However these multiplicative bonuses are different than normal as they are additive when stacked. What this means is you want to spread out into every type of Multiplicative bonus a build has access to rather than stacking the biggest one.

In this build, we are looking for the following multiplicative stats without over stacking:
Critical Strike Damage multiplier, Vulnerable Damage multiplier, Physical Damage multiplier, and All Damage multiplier.

Movement Tech

The last way to scale your damage is a small one but it has a big impact. When you're fighting bosses, try to walk around the boss the opposite way your Bone Spirits are circling. This will increase the number of hits your Bone Spirits do by getting them to the enemy faster for another hit.

How The Mobility Works

Inexorable Reaper Sever has become the strongest tool in the Necromancers arsenal for incredible mobility.
Unlike in previous seasons when it was an aspect, Inexorable Reaper Sever now has its mobility scale with Attack Speed - the faster you cast Sever the faster you move.

And because this build is already stacking Essence Regeneration for Bone Spirit it means we can spam this as much as we want for unlimited mobility.

This pairs perfectly with Astral Projection Bone Spirit to create a playstyle similar to that of Ball Lightning Sorcerers and Hammerdin Paladin builds.

How To Generate Essence

This build heavily relies on Essence Regeneration affixes for its Essence gain, making greater affixes in wherever you can roll the stat a must have priority.

Gift of Death Skeleton Mage offers a rare multiplicative bonus to our Essence Generation, making every stat of it we can get in our gear extremely powerful. If you sudden ly feel like you have less Essence Generation than you remember, make sure you have the correct upgrade and that they're still alive.

Greater Affix Essence Generation in our rings also plays a massive part in our ability to reach enough Essence Regeneration to be able to spam Astral Projection Bone Spirit.

a single Lucky Hit Primary Resource temper also makes into the build to help gain extra Essence when fighting bosses.

How The Grouping Works

This build utilizes an amazing combo between Godslayer Crown, Dizzying Curse Decrepify, and the Desecrated Charm set to instantly pull rooms of mobs instantly into your death blender Astral Projection Bone Spirit.

The way the combo works is as following:

  1. Crowd Control and Corpse Generation Sever will serve as our mobility as well as generate a corpse when it hits something.
  2. The Desecrated Charm set will then apply to everything around the corpse.
  3. Dizzying Curse Decrepify will apply a daze when applied which will then trigger Godslayer Crown
  4. If that fails, we have Wat and Moni to help keep the CC combo continuous and seamless.


Why Desecration Charm Set Over Bone Weaver

While the Bone Weaver set is an amazing set in its own right, the Desecration Charm Set just sets this build up much better for what it wants to do, making it both faster and stronger.

The first is the Desecration set makes the build play faster, giving players a zero button Godslayer Crown pull through the combination of Dizzying Curse Decrepify and the 3 set effect.

The second main benefit is that the Desecration set offers more damage.
The Bone Weaver set grants 50%[x] Crit Damage bonus and another 175%[x] from the 5 set.
The Desecration set on the other hand offers 225%[x] just off its 5 set effect, with an additional 30%[x] off the 2 piece effect.

This does come at a cost of less Essence Generation. But with proper gearing the build is easily able to overcome that issue to enjoy higher damage, smoother gameplay, and fixing one of the core problems the build used to face.
