Hemomancer Diablo IV Necromancer Build

Hemomancer Necromancer BUILD for Diablo IV

(the Hemomancer will bleed you dry and consume your vitality to keep themselves Healthy)

♦ ◊ ♦ ◊ ♦

Diablo IV launches on June 6th, 2023 for PC (Battle.Net), XBOX, & PlayStation with a 4 days Early Access (no wipe) for pre-orders (so kind of really launching June 2nd).

Diablo IV’s Open Beta Tests are almost here and I felt motivated to make some Pre-Launch theorycrafted semi-builds that should be good for ‘fresh-into-endgame’ characters when the game launches. I also plan to evolve them into FULL builds when the game is released & keep them updated when we get rebalance updates. This is one such build for the Necromancer Class called Hemomancer. (you can call it Mrs. or Ms. bones if suits you better

The Beta tests will only let us reach lvl 25 and only let us play in the first Act/Zone (Fractured Peaks) so those builds will be more useful for the actual game launch and ideally for characters around lvl 50+ or 60+. I’ve used 50+ and 60+ skill points when making the builds instead of the full 100 so that they can be used to jumpstart a player’s post-story endgame grind.

I’ve also made spreadsheets for those builds (see the links below) that have shortlisted the active and passive skills + legendary aspect that work well with the build so one can spend the extra skill points on the way to lvl 100 into those other skills.

This build will be updated post-launch to a new & expanded version when I have actual in-game information as reference.

Skill Trees

Below you’ll see ONLY the Active & Passive skills that were selected for this build. For additional skills that can be taken on the way to lvl 100 + alternative skill options, you can check my pre-launch builds spreadsheet on this link. This build (Hemomancer) is one of the builds on that spreadsheet.

The images you see are PLACEHOLDERS due to lack of any real skill icons leaks for the Necromancer class. I will replace them once the Beta starts and I can screenshot the actual icons.

Specializations (Required Points: 33 )

Book of the Dead (Class Mechanic):

This build is all about doing as much shadow dmg hits as possible and focuses on ranged DPS. Sacrificing our melee minions might make it hard by not having a “tank” but it also boosts our dps in a lovely way. As for the types I picked, I’d recommend as follows:

  • Skeletal Reapers + Sacrifice is what we take for the bonus dps
    • Description: Your critical strike chance is increased by 5%, but you can no longer raise Skeletal Warriors.
  • Shadow Mages + Sacrifice is a lovely build synergy
    • Description: Your maximum essence is increased by 15, but you can no longer raise Skeletal Mages.
  • Iron Golem + Sacrifice is what we take for the bonus dps
    • Description: You deal 30% (multiplicative) increased critical strike damage, but you lose the ability to summon a Golem.

Legendary Aspects / Powers

I will only list the Legendary Aspects that have been selected for the build and the slots in which I advise putting those. For in-depth information you can check my pre-launch builds spreadsheet on this link. This build (Hemomancer) is one of the builds on that spreadsheet.

  • Helm: Aspect of Potent Blood
  • Amulet: Aspect of Shared Misery
  • Chest: Fastblood Aspect
  • Pants: Aspect of Might
  • Gloves: Aspect of Pummeling
  • Boots: Aspect of Grasping Veins
  • Ring 1: Aspect of The Umbral
