The Necromancer has always been one of Diablo IV gold most flexible classes, but few playstyles capture its destructive potential as dramatically as the Shadowblight Nuke Build. Built around Shadow damage over time, overlapping procs, and the explosive potential of the Shadowblight Key Passive, this setup transforms your Necromancer into a walking corruption engine. With the right synergy, enemies don't simply die-they detonate in waves of cascading shadow explosions. This build thrives in endgame content, excelling in high-tier Nightmare Dungeons, open-world farming, and late-game boss encounters.

Understanding the Shadowblight Core

The entire build centers on the Shadowblight Key Passive, which triggers bonus Shadow damage after inflicting enough Shadow DoT instances. Every attack-or minion hit-that deals Shadow damage contributes to stacking Shadowblight. Once triggered, it detonates near the target, and when you're hitting multiple targets simultaneously, these detonations begin chaining across entire packs.

The "nuke" aspect comes from layering multiple sources of Shadow damage:your main skill, your secondary DoTs, Lucky Hit effects, and any minion attacks you allow into the build. The more rapid hits you produce, the faster Shadowblight procs. That means high attack speed, continuous damage uptime, and frequent AoE application are the keys to maximizing output.

Skill Setup and Rotation

While there are variations of the Shadowblight build, the strongest versions typically revolve around Sever or Blight.

Sever Variant

Sever excels at creating fast-hitting, multi-instance Shadow damage. The spectral scythe slices through enemies, generating constant Lucky Hit checks that accelerate Shadowblight stacking. Its mobility and reach make it ideal for clearing quickly in tight dungeon corridors.

Blight Variant

The Blight build creates persistent pools of Shadow corruption. These pools slow enemies, making them easier to control, and provide constant damage ticks that repeatedly trigger Shadowblight. While slightly slower-paced than Sever, Blight offers superior area denial and synergizes well with corpse manipulation tools.

Essential Support Skills

Corpse Tendrils remains a cornerstone of almost every Necromancer DPS build. Pulling enemies together not only enhances AoE potential but ensures that Shadowblight detonations chain through enemies without wasted procs.

Decrepify adds crucial survivability, damage reduction, and cooldown benefits while enhancing Shadow output.

Blood Mist serves as your emergency escape tool, providing immunity and repositioning. With the right aspect, it also becomes a Shadow damage source.

Key Passives, Paragon, and Glyphs

Following the Shadowblight passive, the Paragon Board elevates the build into a top-tier endgame powerhouse. Prioritize Darkness, Shadow damage, DoT multipliers, Vulnerable damage, and Intelligence nodes. Glyphs such as Scourge, Exploit, and Darkness provide significant scaling, especially once leveled past Tier 15.

The goal is simple:amplify all sources of consistent Shadow damage while boosting the frequency and power of Shadowblight detonations.

Legendary Aspects That Define the Build

A handful of Aspects dramatically improve performance:

Aspect of Grasping Veins-Provides huge Critical Strike bonuses after using Corpse Tendrils.

Blighted Aspect-Amplifies damage taken by enemies standing in your Blight pools.

Aspect of Decay-One of the strongest multipliers for Shadowblight's explosion damage.

Accelerating Aspect-Boosts attack speed, which increases Shadowblight proc rate.

Aspect of Disobedience-Adds essential defensive scaling for high-tier Nightmare runs.

Whether you play with or without minions, these Aspects form the backbone of the build's offensive and defensive identity.

How the Build Plays

In practice, the Shadowblight Nuke build creates a rhythmic loop:pull enemies in with Corpse Tendrils, weaken them with Decrepify, apply your main Shadow skill, and let overlapping damage instances flood the battlefield. Once the Shadowblight procs begin, the screen erupts in chained explosions that wipe out elites and bosses with surprising efficiency.

For players who enjoy a mix of tactical crowd control and overwhelming burst damage, the Necromancer Shadowblight Nuke build stands as one of Diablo 4 gold most satisfying and visually devastating endgame setups.
