Shadowblight Summoner – Necromancer Build For Diablo 4 (Season 13)

Build Introduction

The Shadowblight Summoner build looks like any regular Minion build focusing on Skeleton Warriors, but it is much more complicated. The build concept is not only to act as a regular The Gloom Ward Shadowblight variant with Black Shroud Set, but to be able to mitigate the conflicting mechanic of the set, with alpha strike using Skeleton Warrior active ability to start Shadowblight before set powers create stray Corruption effects interfering with Shadowblight counter.

Skill Tree Points and Skill Bar

Suggested Skill Bar

SeverCorpse TendrilsGolemSkeleton WarriorHemorrhageBone Storm

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.

Iron Maiden and Decrepify are activated via Blood Moon Breeches and are not needed on the skill bar. Decrepify ranks above 1 are the lowest priority and are leveled by the last Skill Points remaining.

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.

Necromancer Class Mechanic – Book of the Dead

This build continues to use some sacrificed minions for inter-Minion synergies:

• Skeletal Warriors: Reapers [Upgrade #2] -50%[x] increased damage and 15% chance to Stun for 1 second.
• Skeletal Mages: Cold [Sacrifice] – Increased Damage to Vulnerable 20%[x].
• Golem: Bone [Sacrifice] – 10%[+] Attack Speed and Golem does 50%[x] less damage.

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.

Building up Mercenary Rapport and bartering for Aspect Caches or specific Legendaries is a great way to try to obtain specific slot Legendary Aspects early. 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.

Multiple Legendary Aspects and Uniques options are ordered in descending priority order :

Gear Slot	Sockets	Aspect / Unique	Description
Helm	Runeword	Heir of Perdition Exploiter’s Aspect	You have 50%[+] increased Crowd Control Duration. While enemies are Unstoppable, you deal 50%[x] increased damage to them.

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:

• The Gloom Ward is to be equipped, if The Gloom Ward of the desired quality is not obtained and equipped.
• Bloodless Scream is the second most potent Unique Charm for the build.
• Legendary Seal with +1 Charm Slot affix, to unlock 6 Charm slots asap.
• Full Black Shroud Charm Set of any quality. 5-set takes priority over any other Charms except The Gloom Ward if it is still used.
• Charms replacements with better versions of themselves, including affixes like:
  • + to Darkness Skills
  • +%[x] Shadow Damage
  • +% Maximum Life
  • +% Movement Speed
  • +% All Stats

Mercenaries

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

• Flame Surge
• Raging Violence
• Wave of Flame
• Raging Havoc

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

Build Mechanics

This builds purpose is just to stay alive and group up enemies with Corpse Tendrils as tightly as possible for Reapers to use Deathgrip cleave with maximum efficiency. Cleave attacks stack Shadowblight damage from The Gloom Ward fairly efficiently, and even if peak damage ticks are lower, they start stacking due to sheer amount.

Rotation and Playstyle

1. Initiate a fight by sending Golem towards enemies and drawing attention to him.
2. Approach enemies using Sever and immediately use Corpse Tendrils on the corpse created on landing, to pull enemies close together.
3. Send Skeleton Warriors to attack the edge of the highest concentration of enemies.
4. If it is a big pull or boss fight – use multiple Sever casts to produce corpses and use Bone Storm for maximum duration.
5. Keep evading danger and recasting Corpse Tendrils on cooldown, to group enemies tighter for Deathgrip cleaving attacks.
6. Keep focusing Skeleton Warriors with active ability at high-value targets (pit goblins, dangerous multi-affix Elites) or to the edge of density, to make the most from cleaving attacks.
7. Repeat. The rest of the mechanics are completely automated.

Season Updates

Noteworthy changes:

• Built around scaling the reworked Shadowblight mechanic from the new The Gloom Ward Unique
• Slightly altered Blood Moon Breeches, which retained the main function, but became slightly more generic.
• New toolkit for Crowd Control and active damage mitigation
• Mobility issues resolved
