Shadowblight Blight – Necromancer Build for Diablo 4 (Season 13)

Build Introduction

This Blight build is the easiest and likely most potent way to tap into the Black Shroud Charm Set and The Gloom Ward Shadowblight powers. High mobility, extreme damage, and potent crowd control – virtually no downsides besides Blight‘s area of effect size. Shadowblight Blight is expected to be a top contender for the Necromancer meta pinnacle.

Skill Bar and Skill Tree Points

Recommended

Suggested Skill Bar

SeverCorpse TendrilsBone PrisonBlightHemorrhageSoulrift

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, it 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.

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 :

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
2. Wither
3. Frailty – Glyph Slot
4. Scent of Death
5. Scent of Death – Glyph Slot
6. Blood Begets Blood
7. Blood Begets Blood – Glyph Slot
8. Wither – Glyph Slot

It is imperative to level up all Glyphs to level 15 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 build 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.

Rotation and Build Mechanics

The ultimate goal of the build is to provide a consistent stream of stacking Shadow Damage over Time instances to proc The Gloom Ward

Rotation and Playstyle

1. If no corpses are available near the enemy, engage by blinking to their proximity using Sever.
2. Cast Corpse Tendrils on a corpse near the enemy group or one created under your feet after landing with Sever.
3. If mob density poses a threat, the fight may take more than 10 seconds, or you want to take full advantage of Bloodless Scream multiplier – activate Soulrift.
4. Throw Blights at any groups of enemies while replenishing Essence and applying Freeze with Hemorrhage.
5. After Corpse Tendrils pull, cast Bone Prison on the densest grouping of enemies.
6. Stack multiple Blights on top of Bone Prison.
7. Repeat.
