Necromancer Class Mechanic – Book of the Dead

Since we are focusing entirely on dealing brutal damage with our shadow skills, we have no interest in bothering our minions, so they will all be sacrificed in the name of Lilith.

  • Melee Skeletons: If Resistances < 50% Defenders [Sacrifice] – Resistance to All Elements. If resistances are fine then Reapers [Sacrifice] – Increases our Shadow Damage.
  • Mage Skeletons: Cold [Sacrifice] – Increased damage to Vulnerable.
  • Golem: Blood [Sacrifice] – Increased Maximum Life by x#%.

Gear, Stats, Gems, and Runes

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. Additionally, if you are trying to farm a specific item, we recommend using your Obols to target farm them! Other recommendations for Legendary Aspect farming would be to do the Seasonal mechanic and to some extent you can farm them in Helltides as well.

Stat Priority and Tempering Affixes

Below are the affixes to prioritize on gear. Each line of affixes is listed in order of importance. Tempering Manuals and their recommended affixes are provided in the second column, and the bolded affixes are the most important targets for Masterworking upgrades. The main priority for Greater Affixes are marked with a “*”, secondary would be anything providing Intelligence or Life. Be sure to check our Tempering and Masterworking guides for more details about these topics.

Uniques and Mythic Uniques

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

Uniques

  • EbonpiercerEbonpiercer (Required) – Bread and butter of the build as we make our BlightBlight shoot additional smaller projectiles that pierce enemies dealing even more corruption damage.

Mythic Uniques

Some Mythic Unique items can be absolutely insane, but comes at the cost of removing a Legendary aspect power which we are already very short on. Below is a list of Mythic Uniques you could use though:

  • Heir of PerditionHeir of Perdition – Simple helmet replacement. Greater Affix and Masterworking priority on this item will be the Lucky Hit modifier.
  • Shroud of False DeathShroud of False Death – Simple body armor replacement. Greater Affix and Masterworking priority on this item should be on the all stats or split with the Life modifier.
  • Ring of Starless SkiesRing of Starless Skies – This can replace your Creeping Death ring but would also require you to switch out your boss modifier from Beast in the Ice’s Sleet for Sinerat! Greater Affix and Masterworking priority on this item is the Attack Speed.

Boss Powers (Season 8)

The newly added seasonal mechanic lets us power our builds up by using abilities from endgame bosses themselves! Below you’ll find the recommended list for this build.

Main Boss Power:

Modifier Boss Powers:


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, and Varyana as a Reinforcement once you reach endgame.

For the reinforcement, stick with Varyana, utilizing her Bloodthirst skill being cast when the player casts Blight.

Build Mechanics

Rotation and Playstyle

It’s all about spam! You want to utilize Corpse TendrilsCorpse Tendrils to control enemies, followed by BlightBlight for damage output, we further emphasize on our Corruption damage by using Corpse ExplosionCorpse Explosion, this is used to maintain buffs from our Paragon Board and Skill-tree bonuses from consuming corpses. Blood MistBlood Mist is our panic button should all else fail.

Enemies will be cursed by DecrepifyDecrepify if you’re close enough to them which is very important, on top of having very high uptime on SoulriftSoulrift, this builds deals a ton of Shadow damage over time. Adding the damage output of both Blight and Corpse ExplosionCorpse Explosion is one thing, but when we couple that with EbonpiercerEbonpiercer things just melt away!

Which Elixirs Should You Use?

Visit the Alchemist and craft an Elixir providing better resources via Elixir of Resourcefulness IIElixir of Resourcefulness II or if that is fine you can go for the Elixir of Fortitude IIElixir of Fortitude II for Maximum life, should you need armor you could always run Elixir of Iron Barbs IIElixir of Iron Barbs II. Some Elixirs cannot be crafted and only drop from things like Helltides or Nightmare Dungeons. Additionally, make sure to keep your health potion upgraded!
