Hemomancer 2.0 Diablo IV Necromancer Build [RDY-4-Launch]

Hemomancer 2.0 Necromancer BUILD for Diablo IV [RDY-4-Launch]

(the Hemomancer boils the blood of their foes & consumes their flesh to keep themselves Healthy & Fortified)

♦ ◊ ♦ ◊ ♦

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 Launch is getting closer and it’s time to make some Ready-For-Launch full Builds/Theorycrafts that should be good for both ‘fresh-into-endgame’ characters as well as late endgame. I also plan to evolve them further when the game is released & keep them updated when we get rebalance updates. This is one such build for the Necromancer Class called Hemomancer 2.0.

I’ve also made spreadsheets for those builds (see the links below) that have shortlisted the active and passive skills + legendary aspect + unique item + gems & sockets + suggested stat rolls + paragon boards that work well with the build which you can use to tinker. Alternatively, I’ve added build calculator links (mostly needed for the paragons)

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

Book of the Dead (Class Mechanic):

This build is all about creating as many corpses as possible and getting Fortify for each corpse generated. On top of that we can keep spamming Blood Lance as long as we keep consuming the corpses as that gives us Essence. For that reason we take the Corpse generation & Fortify bonuses for our Minions.

I’d advise taking one Minion Type for this build & Sacrificing the other. I prefer using the Skeletal Warriors & Skeletal Mages, while scrapping the & Golem. The types + sacrifices are:

  • Skeletal Reapers: Upgrade 2for that extra Corpse generation
    • Description: Reapers have a 10% chance to carve the flesh off enemies, forming a corpse. This cannot happen on the same enemy more than once every 5 seconds.
  • Bone Mages: Upgrade 2 is amazing to keep granting us Fortify
    • Description: Each time a Bone Mage dies from its own attack, they leave behind a corpse and Fortify you for X.
  • Iron Golem: Sacrifice so that we get extra Crit Damage
    • Description: You deal 30% (multiplicative) increased critical strike damage, but you lose the ability to summon a Golem.

Unique Item

In Diablo IV apparently (I have multiple sources that confirmed this) we can equip more than one unique item at the same time (not so ‘unique’ if we can get decked out in full uniques I guess). It seems that the one unique per build idea that Unique inherited from the Mythical gear they supposedly replaced was scrapped even before the closed beta tests. My top pick will be the following one but check the notes under the Aspects list for some additional picks:

Ring of Starless Skies (Ring)

[6 – 35]% Lightning Resistance
[6 – 35]% Shadow Resistance

Each consecutive Core Skill cast reduces the Resource cost of your next Core Skill by [5 – 10]%, up to a maximum of 30%.

[10 – 18] All Stats
+[4 – 10]% Lucky Hit Chance
+[9.5 – 16.5]% Damage to Crowd Controlled Enemies
+[12.5 – 19.5]% Core Skill Damage

“Yours is the power to pluck the stars from the heavens with the ease of a child gathering fruit from the bough.” – Unknown

Sockets & Gems

There are various possible good/viable choices for the gem slots. I’ve shortlisted what works by slot. I’d recommend picking one of those:

Weps: Weps: Emerald, Saphire, Ruby, Diamond, or Skull.
Armor: Ruby, Skull, or Saphire.
Jewelry: Diamond unless you need specific resistance more than all.

XYZ Diamond (Requires Level XY)

• Weapon: +N% Ultimate Skill Damage

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 RDY-4-Launch Builds spreadsheet on this link. This build (Hemomancer 2.0) is one of the builds on that spreadsheet.

  • Helm:Aspect of Might / Harlequin Crest (see notes below)
  • Amulet: Smiting Aspect / Melted Heart of Selig (see notes below)
  • Chest: Viscous Aspect
  • Pants: Aspect of the Embalmer / Temerity (see notes below)
  • Gloves: Aspect of Rathma’s Chosen
  • Boots: Exploiter’s Aspect
  • Ring 1: Aspect of Grasping Veins
  • Ring 2: Blood Seeker’s Aspect / Ring of Starless Skies (see notes below)
  • 1H Weapon: Aspect of Hungry Blood
  • Off-hand: Cadaverous Aspect
  • 2-H Weapon (if you decide to use one): Aspect of Hungry Blood
NOTE 1: Blood Seeker's Aspect goes in the Ring slot ONLY until you get the Ring of Starless Skies Unique Ring.
There are three other alternative picks for Uniques you could use if you get those first: Melted Heart of Selig (Amulet), Harlequin Crest (Helm), & Temerity (Pants)
See the notes below for more info:

NOTE 2: How to re-arrange if using any of the alternative Uniques:
- For Melted Heart of Selig (Amulet): Smiting Aspect gets removed from the Amulet slot to make room for the Unique Amulet
- For Harlequin Crest (Helm): Aspect of Might gets removed from the Helm slot to make room for the Unique Helm.
- For Temerity (Pants): Aspect of the Embalmer gets removed from the Ring 2 slot to make room for the Unique Pants.

Paragon Boards:

Use the links below to check the paragon boards selected and the nodes I’ve taken. One link is for what the boards will look like at lvl 89 without any paragon points from renown (so more paragon points will be obtained on the way to 100 as well as from renown). The other link will be what the boards will look like when fully maxed out on paragon points.
