Build Overview

There are many Damage over Time abilities available in the game, however, Necromancer Class is the king of them all. Most of your Damage comes from the Corpse Explosion augmented by the Blighted upgrade, which turns the Direct Damage into overlapping Damage over Time area for 6 seconds. If you are lucky enough, you can use the Howl from Below Gloves which will make the Corpse Explosion automatically target nearby Enemies, and deal more Damage while doing so. You also have the Bligh Skill at your disposal, which also deals decent Damage, and have great utility in the form of permanent Slow and increasing the Damage enemies take from you. To begin your Combo you should start with the Decrepify Curse, which Slows your Enemies and grants you a chance to reduce all your Cooldowns by 1 second when you land a Lucky Hit. Then you want to use the Blood Mist which makes you Immune and automatically spawn and detonates Corpses as you move around. At that point, most of your enemies will be dead, but you can use the Corpse Tendrils to gather all remaining monsters and use the newly created Corpses to finish them off.  

This playstyle requires a certain rhythm, but once you get used to it, it's very satisfying. Running out of Corpses to Detonate can certainly slow you down, but if you manage your Cooldowns properly, you will be severely rewarded with massive amounts of Damage. It is also a very tanky and safe style, allowing you to explore the high-end content without problems. 

Please keep in mind, that the following Guide explains the basic variant of the build, without diving into all alternative variants that may utilize different utility skills for various benefits. This will be obviously updated as we have a chance to test out this build properly in the actual game.

 Great utility  




BLIGHT [5/5]

A Core Skill that creates a damaging effect on the ground. You mostly want to use it to inflict Slow and apply a debuff on enemies. It deals less Damage than Corpse Explosion, but you can cast it as you have any Essence left. Optionally you can use the Blood Surge Skill instead to improve your survivability through Healing and Fortify


  1. Enhanced Blight [1/1] - enemies Damaged by Blight are Slowed by 25%. 
  2. Supernatural Blight [1/1] - you deal 15% more Damage to enemies standing in your Bligh's Area.



Your main source of Damage, and Essence generator. It detonates a nearby Corpse to deal Damage. You will need to kite monsters around it so they don't run out of its reach. 


  1. Enhanced Corpse Explosion [1/1] - simply improves the radius of Corpse Explosion. 
  2. Blighted Corpse Explosion [1/1] - instead of Direct Damage, it creates a damaging puddle on the ground. The puddle deals 110% of the Corpse Explosion base Damage, so investing Ranks into this Skill is still important. 



You will need to assign 2 Points here just to unlock the remaining Skills. At first, it is a very useful skill to generate Corpses, but you can stop using it later on. 


  1. Enhanced Decompose [1/1] - improves your Essence generation a bit. 



A very powerful defensive and offensive ability at once. It makes you Immune to all Dmage for a short moment, and thanks to the Legendary Aspect and its upgrades it creates and detonates Corpses for free. 


  1. Enhanced Blood Mist [1/1] - sometimes you will reduce the Cooldown of Blood Mist for free.  
  2. Ghastly Blood Mist [1/1] - creates a Corpse every 1 second. 


It is an important Curse Skill that Slows enemies and Reduces the Damage they deal.  You should always start your Combo with this ability.


  1. Enhanced Decrepify [1/1] - grants your Abilities a chance to Stun enemies affected by this Curse.  
  2. Abhorrent Decrepify [1/1] - hitting enemies affected by Decrepify will sometimes reduce all your remaining Cooldowns by 1 second. 



A very powerful utility tool available for the Necromancers. Tendrils reach out from the targeted Corpse in a wide range and quickly come back Pulling and Stunning all affected enemies.


  1. Enhanced Corpse Tendrils [1/1] - enemies affected by Tendrils are also Slowed.
  2. Plagued Corpse Tendrils [1/1] - Pulling enemies also inflict Vulnerability status on them. 



Your Ultimate Ability makes you very safe for the whole duration of it. It grants you a 15% Damage Reduction, and thanks to the Legendary Aspect you will gain tons of Barrier. Another Aspect also adds a decent amount of Damage to its Hits. 


  1. Prime Bone Storm [1/1] - during the Storm you will gain a 15% Damage Reduction.


Passive Skills


Your main source of additional Corpses to Explode. 


Consuming a Corpse generates 6 Essence, which turns your main ability into a generator.


Exploding a Corpse or summoning Tendrils will increase your Damage for seconds.


You deal increased Damage against enemies affected by your Decrepify.  


Improves your battle potency against Close enemies.


Grants Movement Speed for 3 seconds after damaging an enemy with Shadow Damage.

GLOOM [3/3]

Grants up to 18% increased Damage with Darkness Skills.

TERROR [3/3]

Improves your Shadow Damage against Slowed and Stunned enemies. 


Sacrificing your Minions has added benefit of increasing your Damage Reduction significantly. 


Improves the bonuses you gain from Sacrificing Skeleton Warriors and Mages. 


Key Passive



The only viable choice here, it increases your Shadow Damage by 10%. Every 10th Hit You deal, it will mimic it for 22% of the Damage dealt. 


Book of the Dead


Skeletal Warriors

You should sacrifice the Skeletal Reapers to gain a 10% increased Shadow Damage bonus. 

Skeletal Mages

Skeletal Mages should also be sacrificed. Here it is best to use Cold Mages to increase your Vulnerability Damage. 



You can sacrifice the Bone Golem to improve your Attack Speed, but using Blood Golem to improve your maximum Life is also a good option.  



As Damage over Time cannot inflict Critical Strikes, you have to heavily focus on the Vulnerable Damage (not the Damage against Vulnerable enemies!) everywhere you can, as it is the most powerful Damage Multiplier available currently. Additional Ranks for Corpse Explosion increased Lucky Hit Chance, and Cooldown Reduction is also important. Other than that try to look for various Damage increases, and ways to reduce incoming Damage. Intelligence is also very helpful in that regard. 

In your Weapon, you should aim for the Amethyst Gem, which increases the Damage over Time. In armor, you can use Ruby for generic defense value, or Topaz to reduce incoming Damage when you need it the most. Your Jewelry slots should be filled with Skulls for additional Armour. 


Andariel's Visage (Helmet) - grants Attack Speed and Life Steal. It is also a source of another DoT effect for the build.

  1. Aspect of Explosive Mist is a very important Aspect that makes your Blood Mist trigger free Corpse Explosions.
