Build Introduction

This guide is a collaboration between GhazzyTV and community member Garm Z. The Blood Wave build, despite significant nerfs, still is expected to be the one of top-performing Necromancer builds in Season 8 due to Blood & Shadow scaling unity. Highly gear dependent and expensive build delivers performance worth the price.

There will be plenty of required items for this build to work as listed down below in this guide in detail.

This video shows only the base build interactions and does not include Seasonal Powers.

Necromancer Class Mechanic – Book of the Dead

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

  • Melee Skeletons: Defenders [Sacrifice] – Resistance to All Elements.
  • Mage Skeletons: Bone [Sacrifice] – Increased Overpower damage.
  • Golem: Iron [Sacrifice] – Increased Critical Strike Damage.

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! Outside of Obols to get your Legendary Aspects the recommendation is to engage with the seasonal mechanic as they are often lucrative in terms of Legendary drops and to some extend farming Helltide areas.

Make sure to achieve and maintain armor cap of ~1,000 as soon as possible! For that purpose helm or chest temporary tempering can be Total Armor % and/or Spiked Armor ranks.

Mercenaries

Mercenaries provide a nice extra layer of power to your character and mostly comes down to preferential decision. Below you’ll see the set-up I personally would run for this build which is having Raheir as the Mercenary and for reinforcement I’d use Aldkin!

Aldkin Reinforcement choices:

  • Opportunity Skill: Skill Cast – Whenever the player casts Blood Wave.
  • Reinforcement Skill – Field of LanguishField of Languish

Build Mechanics

Rotation and Playstyle

The entire playstyle is all about grouping enemies together then explode with tsunami’s of actual Blood WaveBlood Wave that comes crashing down obliterating your enemies.

We will utilize Corpse TendrilsCorpse Tendrils to help group enemies together and generate Blood Orbs that we consume to consistently be able to spam our Blood Waves. The Darkness skills on our action-bar is mainly there to scale the passive node Reaper's PursuitReaper’s Pursuit.

For hairy situations where you need to get out of harms way we have Blood MistBlood Mist.

Which Elixirs Should You Use?

Visit the Alchemist and craft an Elixir providing any Resistance you need most, or the Elixir of Fortitude IIElixir of Fortitude II to increase Maximum Life. Some Elixirs cannot be crafted and only drop from things like Helltides or Nightmare Dungeons. Additionally, make sure to keep your health potion upgraded!
