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.

Infernal Hordes put heavy emphasis on AoE (Area of Effect) damage, speed, and build efficiency. You'll face 60-second waves, earn Infernal Offers (bonuses with trade-offs), and eventually reach a final boss fight that determines your loot yield. For every enemy you kill, you gather Burning Aether, which can be used at the end to open chests-more Aether equals more loot.

If you want to thrive in Infernal Hordes and maximize your rewards, choosing the right build is essential. Here are the best builds and recommended Diablo 4 Items to help you dominate Infernal Hordes in Diablo 4 Season 9: Sins of the Horadrim.

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 cheap Diablo 4 Items both waves and bosses like the Fell Council.
