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

Build Introduction

This Blood Wave build relies on the Path of Darkness upgrade and full Black Shroud Charm set to make the most of The Gloom Ward Shadowblight power. While being quite expensive to gear and setup-heavy in terms of playstyle, its performance makes it worth the effort. Shadowblight Wave is a strong challenger for the crown in the Necromancer meta.

Skill Bar and Skill Tree Points

Recommended

Suggested Skill Bar

SeverIron MaidenBlightBlood WaveHemorrhageBone Prison

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 :

Gear Slot	Sockets	Aspect / Unique	Description
Helm	Runeword	Heir of Perdition Aspect of Debilitating Darkness	Your Desecrated Ground deals 25%[x] increased damage and makes enemies

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 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 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
  • Cooldown Reduction
  • +% 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

This build rotation is designed to reset the cooldown of Blood Wave by semi-automated generation and consumption of Blood Orbs. Besides that, skills rotation is tailored for naturally activating most damage multipliers for the next Blood Wave cast. The ultimate goal of the build is to provide a stream of normalized high Shadow damage instances to proc The Gloom Ward.

Rotation and Playstyle

1. If Blood Wave is on cooldown and Blood Orbs are available in the vicinity, pick them up using Blood Maiden casts.
2. Engage enemies by cursing most of them with a few Blood Maiden casts.
3. Apply Whirlpool Blights and Blood Runs Cold Hemorrhage to Freeze as many non-Boss mobs as possible and generate Blood Orbs.
4. Keep generating Blood Orbs using the previous step and collecting them with Blood Maiden casts until Blood Wave is off cooldown.
5. Reposition yourself to be able to hit most of the frozen enemies if you are using Kessime’s Legacy.
6. Cast Bone Prison, covering as many enemies as possible, followed by Blood Wave.
7. If too many enemies are still alive and close, disengage and pull back a bit of distance, letting Spirit Wolves grab the aggro.
8. Repeat.

Cooldown Reduction Contributors

Cooldown Reduction engine is a set of abilities, upgrades and buffs that reduce active cooldowns by fulfilling certain conditions. This build relies primarily on Fastblood Aspect and Blood Orb collection. Secondarily, it uses Lucky Hit against enemies cursed by Decrepify with the Cooldown Reduction upgrade, which is automatically applied by Igni Wat runeword.

Lucky Hit triggers:

• Aldkin mercenary Flame Surge (AoE)
• Blight (high Lucky Hit Chance, AoE)
• Blood Wave (high base Lucky Hit Chance, AoE)
• Hemorrhage (high base Lucky Hit Chance)
• Ceh Spirit Wolf (high base Lucky Hit Chance)

Blood Orb sources:

• Hemorrhage Blood Orb and Blood Runs Cold upgrades
• Aspect of Transfusion triggered by Hemorrhage
• Blood Maiden
• Decrepify Life Tap
• Blood Wave Blood Orb upgrade
