The top builds for pushing high tiers in The Pit during Diablo 4 Season 9: Sins of the Horadrim are based on their ability to efficiently clear high-difficulty content, leveraging new uniques, Horadric Spells, and balance changes. Below is a concise breakdown of the best builds for each class, focusing on their performance in Pit 100+ content, based on recent web sources and community discussions. Note that some builds may be affected by bug fixes or nerfs post-launch, so keep an eye on patch notes.

S-Tier Builds for Pit Pushing (Top Performers)

1. Spiritborn: Balazan Quill Volley
   • Why It’s Top-Tier: This build dominates with massive projectile damage via Quill Volley, enhanced by the new unique Balazan’s Maxtlatl, which boosts Thorns and Poison synergies. It cleared Pit 115 in under 4 minutes on the PTR, with high mobility and tankiness via Noxious Resonance. Even if the double-dipping Jaguar Spirit Hall bug is fixed, it remains S-tier, capable of Pit 110+.
   • Key Items: Flesh Reaper, Vasharn’s Boss Power, Accursed Touch, Starless Skies.
   • Pros: Accessible gear, scalable damage, excels in Pit and Helltides.
   • Cons: Slightly lower sustainability compared to other S-tier builds.

2. Sorcerer: Hydra Sorcerer
   • Why It’s Top-Tier: The Hydra Sorcerer is a standout due to the new Ophidian Iris unique, enabling massive Hydra summons (up to 12 heads) with high burst damage. It clears Pit 105+ and Torment 4 bosses with ease, even without fully optimized gear. The build focuses on mana management and synergies with Serpentine Aspect and Axial Conduit.
   • Key Skills: Hydra, Fireball, Teleport, Ice Blades, Inferno.
   • Key Items: Serpentine Aspect, Tal Rasha’s Loop, Flash Fire, Shroud of False Death.

3. Necromancer: Shadowblight Minion (Zoomancer)
   • Why It’s Top-Tier: The “Zoomancer” leverages an autonomous undead army with Shadow-enhanced skeletons and golems, boosted by Ring of Mendeln for massive AoE and single-target Shadow bursts. It excels in Pit 90+ due to high survivability and consistent DPS via Service and Sacrifice and Occult Dominion aspects.
   • Key Skills: Decrepify, Bone Prison, Army of the Dead, Blight, Soulrift.
   • Key Items: The Hand of Naz, Shroud of False Death, Mendeln.

A-Tier Builds (Strong but Not S-Tier)

1. Barbarian: Flay Barbarian
   • Why It’s Strong: Flay Barbarian was briefly overpowered on the PTR due to a bug with Hooves of the Mountain God, enabling Pit 150 clears via negative damage. Post-fix, it’s expected to drop to A or B-tier but remains viable for Pit 90–95 with high-damage bleed synergy from Ramaladni’s Magnum Opus and Shard of Verathiel.
   • Key Skills: Flay, Berserk Ripping, Fists of Fate.
   • Pros: Tanky, mobile, great for solo and group play.
   • Cons: Relies on bug fix for top performance; otherwise, mid-tier.
   • Source:
2. Necromancer: Blood Wave Necromancer
   • Why It’s Strong: Despite nerfs, Blood Wave remains a reliable A-tier build for Pit 90–100, with strong scaling and control via Horadric Spells. It’s less autonomous than the Zoomancer but offers high burst damage.
   • Key Skills: Blood Wave, Blood Mist, Decrepify.
   • Pros: Solid for Pit and bossing, good survivability.
   • Cons: Outshined by Zoomancer for ease of use.
   • Source:
3. Druid: Earth Spike Druid
   • Why It’s Strong: This build uses Seismic-shift Aspect to remove Earth Spike’s cooldown, turning it into a spammable, high-damage skill. Enhanced by Shard of Verathiel and Vasily’s Prayer, it offers tankiness and AoE for Pit 90+.
   • Key Skills: Earth Spike, Grizzly Rage, Cyclone Armor, Blood Howl.
   • Pros: Simple gameplay, high tankiness, great AoE.
   • Cons: Requires setup for optimal performance.
   • Source:
4. Rogue: Flurry Rogue
   • Why It’s Strong: Flurry Rogue delivers insane AoE burst and mobility with Aspect of Encircling Blades, excelling in Pit 90+ and nightmare dungeons. Deathmask of Nirmitruq and Doombringer boost offense, while Shroud of False Death adds survivability.
   • Key Skills: Flurry, Caltrops, Dash, Shadow Step.
   • Pros: Fast-paced, great for dungeon clears.
   • Cons: Weaker single-target damage compared to S-tier builds.
   • Source:

Notes

• Meta Context: Season 9’s meta is shaped by Horadric Spells, new uniques, and reduced monster health scaling in higher Pit tiers, making Pit 100+ more accessible. Spiritborn and Sorcerer dominate due to their synergy with these mechanics.
• Potential Nerfs: Flay Barbarian, Hydra Sorcerer, and Poison Volley Spiritborn rely on double-dipping bugs, which may be fixed post-launch, potentially lowering their tier. Monitor patch notes for updates.
• Playstyle Fit: Choose a build that matches your preferred playstyle. For example, Zoomancer is low-effort, while Hydra Sorcerer requires active mana management.
