Season 9 of Diablo 4 introduces a new endgame gauntlet:the Infernal Hordes. Found in the Realm of Hatred, this mode drops players into a series of time-limited enemy waves, where efficiency and damage output determine your survival and rewards. Each run is built around three key pillars:

Burning Aether:Collected from slain enemies and spent at the end on chests for loot.

Infernal Offers:Risk-versus-reward modifiers that boost your power but also increase the challenge.

The Fell Council:A culminating boss fight where your performance decides the final haul.

Entry requires an Infernal Compass, but succeeding requires a powerful build. Below are the top options for Diablo 4 Season 9:Sins of the Horadrim, all perfectly suited for farming Burning Aether and mowing through endless waves of demons.

1.Hydra Sorcerer – Unstoppable Flames

The Hydra Sorcerer is a wave-clearing machine in Season 9 thanks to the Ophidian Iris amulet, which doubles Hydra damage and spawns each as a three-headed beast. With scaling mechanics that increase head count and size, Hydras quickly cover entire arenas in fire.

This build excels because the Hydras do most of the work for you – burning mobs while you reposition or control the fight. Combined with Pyromancy passives, it offers incredible AoE, consistency, and safety.

2. Quill Volley Poison Spiritborn – Toxic Rain of Arrows

The Poison Spiritborn uses the Rod of Kepeleke to turn Quill Volley into an auto-critical, max-size basic skill. The screen floods with poisoned projectiles, overwhelming both hordes of trash mobs and tougher elites.

It's particularly strong in the compact maps of Infernal Hordes, where space control matters most. Gear investment is required, but once online, it's one of the most dynamic and lethal hybrids for both waves and bosses.

3. Pulverize Druid – Poison Quake Crusher

The Pulverize Druid is built for durability and devastating area damage. With the Rotting Lightbringer, every Overpower triggers a 600% poison burst over seven seconds, stacking poison explosions with seismic slams.

While slower than some options, it's gear-friendly, durable, and beginner-accessible, making it an excellent entry build for players who want a sturdy option to farm Infernal Hordes.

4. Balazan Poison Rake Spiritborn – Thorns That Kill

This Spiritborn setup punishes enemies just for daring to attack. By pairing Razorplate with Balazan Maxtlatl, you stack enormous poison-based Thorns damage. Enemies melt simply by hitting you.

It's a semi-passive, low-APM build, perfect for relaxed farming or multitasking while waves die around you. The trade-off? It lacks burst potential and can be punished by ranged enemies if not carefully managed.

5. Blood Wave Necromancer – Explosions Everywhere

Even after nerfs, the Blood Wave Necromancer remains one of the strongest Infernal Horde options. The Tidal Aspect lets you unleash multiple waves, while Kessime Legacy pulls enemies together and amplifies corpse-based detonations.

The build shines at wave control and AoE nukes, making it reliable for farming Burning Aether. It starts to fall off in ultra-high tiers (100+), but for mid-level farming it's among the safest and most effective choices.

6. Whirlwind Quake Barbarian – Perpetual Motion, Constant Quakes

The fan-favorite Whirlwind Barbarian evolves in Season 9 with a quake-generating twist. By combining bleed-stacking Whirlwind with key aspects, you create a battlefield covered in earthquakes while constantly on the move.

It may not match Hydra Sorcerer burst damage, but it offers high mobility, durability, and reliable sustained DPS, making it a top-tier farming build for Infernal Hordes.

The Infernal Hordes are designed to test your ability to clear massive enemy waves quickly while balancing risk and reward. While nearly any build can eventually succeed with strong enough gear, these six stand out for their AoE potential, synergy with Season 9 mechanics, and efficiency in farming Burning Aether.
