Season 9 of Diablo 4 introduces Infernal Hordes, a brutal new endgame mode that pushes players to their limits in the Realm of Hatred. This wave-based challenge drops you into non-stop battles where survival depends on AoE damage, mobility, and efficient clears.

Each run is structured around 60-second enemy waves. As you slay, you gather Burning Aether, a currency spent at the end to open chests—more kills mean more loot. Along the way, you'll encounter Infernal Offers, powerful modifiers that provide tempting bonuses paired with dangerous drawbacks. The final test is the Fell Council boss fight, where your performance determines your ultimate rewards. Entry requires an Infernal Compass, but once inside, the right build is the difference between struggling and thriving.Get your Diablo 4 gold from MMOexp today and dominate every battle with confidence!

Here are the best builds for Diablo 4 Season 9:Sins of the Horadrim—optimized for farming, wave-clearing, and boss control inside the Infernal Hordes.

1.Hydra Sorcerer – Flames That Fight for You

The Hydra Sorcerer dominates this season thanks to the Ophidian Iris amulet, which grants Hydras a staggering +100% multiplicative damage bonus while upgrading every summon into a three-headed firebreather. With scaling head-count mechanics, Hydras quickly turn into an army of self-sufficient wave clearers.

This build lets your Hydras shred mobs on autopilot while you reposition or manage control effects, making it both deadly and safe. With strong Pyromancy synergies, it's arguably the smoothest AoE DPS option in Season 9.

2. Quill Volley Poison Spiritborn – Agile Screen Clear

Using the Rod of Kepeleke, Quill Volley transforms into a massive, auto-critical basic skill that fills the screen with poison-tipped projectiles. The result is a build that blends mobility, AoE dominance, and strong single-target burst.

It shines especially in the tight corridors of Infernal Hordes, where space control is everything. While it demands solid gear to truly excel, its mix of fun gameplay and lethal efficiency makes it a standout for both clearing waves and burning down the Fell Council.

3. Pulverize Druid – Poison Earthquake Powerhouse

The Pulverize Druid thrives in clustered fights, turning every slam into a lethal area nuke. With Rotting Lightbringer, each Overpower releases a poison burst dealing 600% damage over seven seconds, effectively layering earthquakes with venom.

Though it lacks the speed of faster builds, its low gear dependency and natural tankiness make it one of the easiest and most beginner-friendly endgame setups for Infernal Hordes. Perfect for players looking for a sturdy, straightforward way to farm Aether.

4. Balazan Poison Rake Spiritborn – Thorns Made Deadly

This build flips enemy aggression back on them. By pairing Razorplate (Thorns armor) with Balazan Maxtlatl (a poison thorns amplifier), every attack against you returns massive poison damage.

It's a semi-passive playstyle—mobs practically kill themselves just by hitting you—making it a relaxed, low-APM farming option. Great for wave clearing while staying mobile, though it struggles against ranged enemies and lacks strong burst for bosses.

5. Blood Wave Necromancer – Corpses Explode, Enemies Fall

Despite nerfs, the Blood Wave Necromancer is still one of the most reliable AoE builds around. The Tidal Aspect enables multiple waves, while Kessime Legacy clusters enemies together, maximizing corpse-based detonations.

Its strengths lie in wave control and on-demand screen-clearing bursts, making it one of the safest Infernal Horde builds. While it tapers off at the highest tiers (100+), it remains excellent for farming mid-tier content with minimal risk.

6. Whirlwind Quake Barbarian – Endless Motion, Endless Quakes

The classic Whirlwind Barbarian gets a Season 9 twist by pairing bleed-stacking Whirlwinds with earthquake generation. With the right aspects, you can chain Whirlwind + Quake combos almost indefinitely, turning the battlefield into a constant tremor.

It's durable, mobile, and highly reliable, though it doesn't match the raw burst potential of Hydra Sorcerer. Still, for players who enjoy non-stop action while staying on the move, it's one of the most consistent performers in Infernal Hordes.

Infernal Hordes are designed to test speed, AoE efficiency, and endurance. While nearly any build can push through with enough investment, these six stand out for their synergy with Season 9 mechanics, smooth wave clearing, and Burning Aether farming potential.You can cheap Diablo IV Items, which are used by these builds, at MMOexp.
