Blood Wave – Necromancer Build for Diablo 4 (Season 9)

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 9 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.

Follow the points allocated in the Skill Tree above for the complete 71-point build. The additional 10 skill points are completed using the Renown system.

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: Reaper [Sacrifice] – Increased Shadow damage.
• Mage Skeletons: Cold [Sacrifice] – Increased Vulnerable damage.
• Golem: Blood [Sacrifice] – Increased Maximum Life.

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.

Gear Slot	Gems	Aspect / Unique	Legendary Aspect / Unique Power
Helm	Ahu + Qax	Aspect of the Cursed Aura	A dark aura surrounds you, inflicting Decrepify and Iron Maiden on enemies who touch it. Curses inflicted this way spread to surrounding targets every 2.5-0.3 seconds and last 4 seconds outside the aura.
Chest	Royal Topaz	Aspect of Hardened Bones	You and your Minions gain 10-30% increased damage reduction.
Gloves	N/A	Vehement Brawler’s Aspect	Casting an ultimate Skill increases your damage by x#% for 8 seconds. Gain 2 additional Ultimate Skill Ranks.
Pants	Royal Topaz	Kessime’s Legacy	Blood Wave now creates a wave on each side of you and converge at your feet pulling enemies in as well as increasing the damage they take from your Blood Wave.
Boots	N/A	Aspect of Metamorphosis	When you Evade you turn in to a cloud of bats, becoming Unstoppable for 2.5 seconds. Enemies along your path take X Physical damage and are inflicted with Vampiric Curse. Evade’s Cooldown is increased by X seconds.
Weapon 2H (Mace)	Cir + Vex	Aspect of Ultimate Shadow	Blood Wave is now a Darkness Skill and deals Shadow damage. Blood Wave creates Desecrated Ground as it travels, dealing # Corrupting Damage over 4 seconds.
Amulet	Idol From Below	Fastblood Aspect	Blood Orbs reduce your Ultimate Cooldown by # seconds.
Ring	Scornful Light	Tidal Aspect	Blood Wave fires 2 additional wave, each dealing X% of normal damage, but you can no longer recast it until the last wave ends.
Ring	Luminate Eye	Aspect of the Damned	You deal x#% increased Shadow damage to enemies afflicted by any Curse.

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.

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.

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

• Kessime’s Legacy (Required) – Bread and butter of the build as it makes your Blood Wave do more damage and pull enemies in. You can find these pants from Lord Zir himself!

Mythic Uniques

• Shroud of False Death – Scales damage by a lot! Greater Affix and Masterworking priority will be on the Maximum life.
• Heir of Perdition – You’ll have to move Cursed aura to your boots and replace the boots aspect with this item to further scale damage. Greater Affix and Masterworking priority will be on the Critical Strike Chance. This item also allows you to free up one of your runeword for any damage options and crit boss power should you chose to run that.

Horadric Spells and Jewels (Season 9)

In Season 9, we will have access to Horadric Jewels and Horadric Spells, granting some absolutely crazy abilities that we’ll utilize to enhance our build’s power. Below, you’ll find a list of the recommended powers we use for this build.

Horadric Spell

Type	Power	Description
Catalyst	Cosmic Anomaly + Blood Wave	Lucky Hit: 20%. Passive: Manifest up to 5 Anomalies that emit particles which deal x% damage over 4 seconds. Active: Command your Anomalies to converge and implode, dealing x% damage per detonation. At Rank 10 while at 5 Anomalies, you are Unstoppable and the next implosion will deal double damage.
Infusion	Nebulous Extract	Your Spell Catalyst now deals Shadow and or Corrupting damage. Enemies hit by it deal x% reduced damage for 7 seconds. While equipped, your Shadow Damage Bonus is equal to that of your highest Damage Type Bonus. At Rank 5 it will deactivate enemy monster summoner effects for 5 seconds.
Arcana	Bloody Charm	Your Catalyst gains a specialized Execute effect for non-Boss enemies with 20% or less Life. Bloody Charm will also execute non-boss enemies with Cosmic Anomaly implosions. Successful executions increase your Attack Speed by 20% for 8 seconds.
Arcana	Tranquil Stone	Invoking your Catalyst grants Unstoppable for 5 seconds whenever it activates.
Arcana	Fractured Core	Your Catalyst deactivates monster Damage Resistance Aura effects for 5 seconds, but you take 15% more stacking damage for the same time.

Horadric Jewels

Use these Jewels over regular gems in your jewelry slots to further enhance the build:

• Idol From Below
• Scornful Light
• Luminate Eye

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!

Raheir Skill Tree choices:

• Ground Slam
• Raheir’s Aegis
• Bastion
• Inspiration

Aldkin Reinforcement choices:

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

Build Mechanics

Rotation and Playstyle

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

We will utilize Corpse 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 Pursuit.

Inside the waves you’ll want to keep up your other sources of damage from Blight and Corpse Explosion which is also used to keep your Flesh-eater buff via the Paragon Board.

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

Which Elixirs Should You Use?

Visit the Alchemist and craft an Elixir providing any Resistance you need most, or the Elixir 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!
