Diablo 4 Season 9: Best Builds for Infernal Hordes

In Diablo 4 Season 9, the endgame has been significantly enriched by Diablo 4 Items new content such as the Infernal Hordes-a fast-paced, wave-based activity found within the Realm of Hatred. The mode offers players a challenging and rewarding experience that revolves around killing hordes of enemies in timed waves, collecting Burning Aether, and ultimately facing off against the Fell Council. To get started, players need an Infernal Compass to access this event.

1. Hydra Sorcerer - Pyromancer's Playground

Key Item: Ophidian Iris (Unique Amulet)
Playstyle: Stationary turret build, AoE nuker
Strengths: High AoE, hands-free damage, Pyromancy synergy

The Hydra Sorcerer returns in Season 9 as a top-tier contender for AoE-focused content, thanks to the introduction of the Ophidian Iris amulet. This item transforms your Hydras into devastating powerhouses, granting a +100% multiplicative damage bonus and turning every cast into a three-headed Hydra (with scaling head-count increasing size and damage).

Hydras will melt entire waves on their own, while you reposition or manage crowd control. Combined with Pyromancy passives and enhancements, this build provides excellent coverage, safety, and consistent AoE DPS.

Recommended Aspects/Spells:

Serpentine Aspect (more Hydra uptime)
Flame Shield (for survivability)
Fireball Enchantment (for added AoE explosions)

2. Quill Volley Spiritborn (Poison) - Burst and Sustain Hybrid

Key Item: Rod of Kepeleke (Unique Weapon)
Playstyle: Ranged AoE with built-in crits
Strengths: High crit rate, poison uptime, mobility

The Quill Volley Poison Spiritborn build is an agile and lethal hybrid that uses basic skill conversion to maximize AoE and single-target pressure. Rod of Kepeleke turns Quill Volley into a max-size, auto-crit, basic skill, allowing it to cover the screen in toxic barbs.

This build excels at controlling space, especially in confined Infernal Horde maps. While gear-dependent, its damage and mobility make it one of the most fun and effective options for both waves and bosses like the Fell Council.

Recommended Mods:

Poison DoT multipliers
Increased Basic Skill Attack Speed
Energy Regeneration or Cooldown Reduction

3. Pulverize Druid - Poison Earthquake Combo

Key Item: Rotting Lightbringer (Unique Mace)
Playstyle: Earthshaking AoE with Poison Overpower
Strengths: Simplicity, poison synergy, high early/mid power

The Pulverize Druid is a tanky, hard-hitting beast that thrives in clustered wave fights. With the Rotting Lightbringer, every Overpower triggers a 600% poison burst over 7 seconds, allowing Pulverize to become a wave-clearing tool of destruction.

It may lack the finesse of faster builds, but its low gear dependency and early strength curve make it excellent for getting into Infernal Hordes without perfect gear. It's also one of the more beginner-friendly endgame builds this season.

Best Aspects/Skills:

Ursine Strength (for Overpower scaling)
Poison Creeper (to group mobs)
Blood Howl (for sustain)

4. Balazan's Poison Rake Spiritborn - Thorns Poison Machine

Key Items: Razorplate + Balazan's Maxtlatl
Playstyle: Tanky Thorns with Poison twist
Strengths: Reflective damage, passive mob-clearing

This build turns the enemy's aggression against them, ultimately leading to their demise. By combining Razorplate (Thorns armor) with Balazan's Maxtlatl (poison thorns amplifier), this Spiritborn build racks up massive passive poison damage with minimal effort.

Enemies die just by touching you, making it a semi-passive build that clears waves even while on the move or focusing on boss mechanics. Its low APM (actions per minute) makes it ideal for relaxed farming. However, it lacks burst damage and is vulnerable to ranged enemies if not careful.

Recommended Gear:

Thorns % mods
Poison Duration/DoT increases
Defensive stats (Armor, DR vs Close)

5. Blood Wave Necromancer - Exploding Corpses Reign Supreme

Key Items: Kessime's Legacy (Unique Pants), Tidal Aspect
Playstyle: AoE screen control via wave spam
Strengths: Safe gameplay, wide AoE, auto-pull

Even after nerfs, the Blood Wave Necromancer remains an elite horde-clearing build. The Tidal Aspect lets you cast multiple waves, while Kessime's Legacy pulls enemies in and boosts explosive AoE from corpse effects.

This build excels in Infernal Hordes thanks to wave control, enemy grouping, and on-demand AoE nukes. While it struggles with scaling deep into Tier 100+ content, it's one of the safest and most reliable for medium-tier wave content.

Enhancements to Prioritize:

Corpse Explosion Damage
Blood Skills Cooldown Reduction
Essence Regeneration

6. Whirlwind Quake Barbarian - Mobile Earthquake Engine

Key Item: Aspect of the Quaking Rage
Playstyle: Perma-spinning AoE juggernaut
Strengths: Smooth gameplay, high bleed + quake synergy

The Whirlwind Quake Barbarian remains a fan-favorite and versatile pick in Season 9. The build combines Whirlwind's fast bleed stacks with quake generation via key aspects. The damage is sustained, wide-ranging, and great for hitting mobs across the screen while moving.

With proper Fury management, you can chain Whirlwind + Quake endlessly. While it doesn't offer the raw nuke potential of Hydra Sorcerer, it makes up for it with durability and mobility.

Key Aspects:

Quaking Rage
Limitless Rage
Weapon Master's Aspect
