Blood Wave – Necromancer Build for Diablo 4 (Season 13)

Build Introduction

This Blood Wave build relies on scaling Overpower with Red Blessing and Hematolagnia to make the ability spammable as your main source of damage! It’s a nice throwback to Season 7 (Season of Witchcraft) where we used to spam our Ultimate skills.

Skill Bar and Skill Tree Points

Recommended

Suggested Skill Bar

Blood WaveSeverIron MaidenBone PrisonHemorrhageSkeleton Warrior

Use the Skill Tree above to complete the 83-point build. 69 skill points are gained by leveling, and 14 skill points are locked behind the Season Rank System or Renown for Seasonal or Eternal characters, respectively.

Decrepify is applied through Wat Runeword, so it is not present on the Skills Bar. Also, Skeleton Warrior is the lowest priority skill and only the last Skill Points are used to level it above 1/15.

The new Lord of Hatred expansion Skill Tree unlocks in stages, permanently unlocking new skill clusters. For example, Necromancer Curses unlock at level 13, so from level 13 it is possible to refund all previously allocated skill points and start leveling skills starting from the Curses cluster right away (or anywhere above it).

Skill points from the Season Rank System or Renown do not affect Skill Tree progress and can be allocated to skill ranks you already unlocked.

Gear, Stats, Gems and Runes

The following sections cover the essential itemization to improve the power of your character in the endgame of Diablo 4.

For the dedicated page on Gear Systems and Itemization Overview, check the guide here.

Legendary Aspects

Each aspect is listed with its matching gear slot. Do your best to keep each aspect in the assigned slot. Aspects placement is planned with potential Unique and Mythic Unique gear upgrades in mind for the easiest and cheapest transition.

The Purveyor of Curiosities is another excellent way to obtain specific slot Legendary Aspects, and even Uniques – by gambling with Murmuring Obols you farmed in your journey.

Choosing Uniques vs Unique Charms

With itemization changes in the Lord of Hatred expansion, Unique gear now has mostly randomized but immutable affixes, like any Legendary item would. It is important to seek pieces with mostly recommended affixes. The Unique Aspect value, if not satisfactory, can be rerolled via Horadric Cube.

Most Unique Aspects can be extracted into a Charm via the Horadric Cube, and generally only one can be equipped in the Talisman system.

For build-defining Uniques, it is worth having both the physical version (with recommended affixes you would expect on a Legendary piece in the same slot) and the Charm version.

A Unique Charm effectively allows you to shuffle two Unique Aspects from the same or conflicting gear slots, or to have a Unique Aspect equipped while the gear slot is occupied by a superior gear piece – until a better version is found.

Paragon Board

Board attachment order and pathways:

1. Frailty – Legendary Node
2. Frailty – Glyph Slot Dominate For the Red Blessing scaling it’s important this Glyph gets the highest priority of being leveled up!
3. Flesh-Eater – Legendary Node
4. Flesh-Eater – Glyph Slot Amplify
5. Scent of Death – Legendary Node
6. Blood Begets Blood – Legendary Node
7. Scent of Death – Glyph Slot Essence
8. Blood Begets Blood – Glyph Slot Control

It is imperative to level up all Glyphs to level 50 first to increase their activation radius, and then to level 51 to unlock the secondary damage multiplier. For more information about Paragon Glyphs and how to level them, see here.

Some paragon points are locked behind the Season Rank System. The remaining Paragon points are used to take all Intelligence nodes you can reach and any Magic nodes you may find useful.

Season 13 Mechanics

Season 13 does not offer specific seasonal mechanics due to the release of the Lord of Hatred expansion. Many new features are available to explore, including War Plans, Talismans, Horadric Cube, and Echoing Hatred. Additionally, several buildcrafting systems were overhauled, such as Skill Trees, Tempering, Aspects and Uniques.

For a complete overview of the current Season, its mechanics and theme, new leveling activities, and other changes, please take a look at our comprehensive season hub here.

Talismans

The Lord of Hatred expansion introduces Talismans as a new character progression and itemization layer. Find, equip, and fill a suitable Horadric Seal with a variety of Charms. These grant everything from plain stats similar to any gear piece to powerful set effects, doubling down on and elevating Necromancer archetypes to new heights.

This builds Talisman goalposts would be:

• Red Blessing is to be equipped, but Red Blessing can serve as a temporary fix till you have it!
• Banished Lord’s Talisman are the second most potent Unique Charm for the build.
• Legendary Seal with +1 Charm Slot affix, to unlock 6 Charm slots asap.
• Full Fer of the Blood Binder Charm Set of any quality. 5-set takes priority over any other Charms except Red Blessing if it is still used.
• Charms replacements with better versions of themselves, including affixes like:
  • + to Physical or Blood Skills
  • +% Movement Speed
  • +% Critical Strike Damage (Seal)

Mercenaries

During the Vessel of Hatred campaign, you will unlock Mercenaries to assist you. While you can choose freely early on, we recommend Varyana as your main merc:

• Cleave
• Hysteria
• Bloodthirst
• Bloodlust

For the reinforcement, stick with Raheir, utilizing Bastion when you are hit with a Control Impairing effect.

Rotation and Build Mechanics

The build is a straight forward Ultimate spam via Hematolagnia for Blood Wave whilst the other skills are either there to help sustain resources, debuffing enemies or buffing your damage output. We ramp our damage the most by scaling Overpower stacks as our main focus.

Rotation and Playstyle

1. Iron Maiden – Use this first to have enemies be cursed.
2. Hemorrhage – The cold version of this Blood Runs Cold to freeze dangerous enemies allowing you to get close and personal without risking your life.
3. Bone Prison – Once you’re close to the enemies you’ll use this to imprison them and amplifies your attack speed.
4. Blood Wave – Spam this as the main source of damage as long as you have enough Essence to cast it.
5. Hemorrhage – This can be repeated to help re-freeze enemies but also get Essence back for you to cast more Blood Wave.
6. Reposition yourself when needed to stay away from harms way whilst still being close to the enemies for optimal damage.
7. Repeat.
