New Best Obducite Farm Season 9 - Diablo 4

In Diablo 4 Season 9: Sins of the Horadrim, Obducite remains a critical resource for Masterworking gear, essential for upgrading high-level Uniques and twice-tempered Legendary items. Below are the most efficient methods to farm Obducite in Season 9, based on the latest information and player insights. These methods focus on maximizing Obducite per minute, with considerations for solo and group play, as well as the new seasonal mechanics like Horadric Strongrooms.

Best Methods to Farm Obducite in Season 9

1. Kurast Undercity with Tribute of Refinement (Best Overall)

• Why It’s Great: The Kurast Undercity, introduced in the Vessel of Hatred expansion, is the fastest way to farm Obducite when using the Tribute of Refinement. This method offers high yields in short runs, especially in group play.
• How to Farm:
  • Acquire Tributes of Refinement: These are random drops from activities like Infernal Hordes, Nightmare Dungeons, or Horadric Strongrooms. Check the Undercity map regularly for Refinement-type Tributes.
  • Run Setup: Complete Undercity runs on Torment 4 for maximum rewards. A single run takes ~2 minutes and can yield 2,000 Obducite solo, or up to 8,000 Obducite in a group of four (if each contributes a Tribute).
  • Group Efficiency: Coordinate with a group using high-mobility builds (e.g., Leap Quake Barbarian, teleport-heavy Sorcerer, or Spiritborn with Vigor regen). Group farming increases spawn rates and clears faster, potentially netting 8,000 Obducite in 8 minutes.
• Pro Tip: Use Seething Opals or other drop-rate buffs to boost Obducite yields. Prioritize runs when you have a surplus of Tributes, as they are not always available.
• Best For: Players with access to Tributes of Refinement, group players, or those with optimized high-DPS builds.

2. Nightmare Dungeons (Best for Solo and Consistent Farming)

• Why It’s Great: Nightmare Dungeons (NMDs) are highly efficient for solo players and offer consistent Obducite drops alongside other materials (e.g., Veiled Crystals, Distilled Fear). They are faster than Infernal Hordes and don’t rely on rare items like Tributes or Compasses.
• How to Farm:
  • Setup: Use Nightmare Dungeon Keys (obtained from salvaging Nightmare Sigils or Tree of Whispers) to access dungeons. Run S or A-tier dungeons (per Icy Veins tier lists) on Torment 4 for optimal rewards.
  • Strategy: Clear the entire dungeon, including events and Corrupted Shrines, which drop additional Obducite. A fast build (e.g., Rogue with 200% movement speed, WW/HotA Barbarian, or Spiritborn Rake) can complete runs in 1.5–2.5 minutes, yielding 1,000–3,000 Obducite per run (averaging ~633 Obducite per minute).
• Pro Tip: Equip a pet to auto-collect materials, use Seething Opals for +100% item find, and allocate Seasonal Ashes to the Obducite drop-rate node. Focus on killing Elites and completing optional objectives for extra reward rooms.
• Best For: Solo players, those farming multiple materials, or players without Tributes/Compasses.

3. Infernal Hordes (High Yield but Slower)

• Why It’s Great: Infernal Hordes provide large Obducite drops via Aether spent on the Spoils of Materials chest, but they require Infernal Compasses and take longer (~10–13 minutes per run).
• How to Farm:
  • Access: Use Infernal Compasses (dropped from Helltide chests, Tree of Whispers caches, Nightmare Dungeons, or The Pit) to enter Hordes on Torment 4.
  • Strategy: Complete 8–10 wave runs to maximize Aether collection. Spend all Aether on the Spoils of Materials chest for 1,500–5,100 Obducite per run (averaging ~289 Obducite per minute). Higher tiers yield more, with Torment 4 offering up to 5,100 Obducite in ~13 minutes.
• Pro Tip: Skip equipment chests to focus on materials. Group play with high-DPS builds (e.g., Sorcerers with Blizzard/Chain Lightning, Necromancers with Corpse Explosion) can speed up runs. Avoid over-farming Hordes due to diminishing returns on Aether-to-Obducite conversion.
• Best For: Players with a stockpile of Compasses or those farming Obducite alongside boss materials.

4. Horadric Strongrooms (New in Season 9)

• Why It’s Great: Introduced in Season 9, Horadric Strongrooms are micro-dungeons that drop crafting materials, including Obducite, and Arcana for Horadric Spellcraft. They are quick and complement other farming methods.
• How to Farm:
  • Access: Found in Nightmare Dungeons or via specific seasonal activities. Higher reputation levels (e.g., level 3 for Rare Arcana, level 6 for Legendary Arcana) increase rewards.
• Strategy: Farm Strongrooms while running Nightmare Dungeons for a combined yield of Obducite and Arcana. Each Strongroom has a chance to drop Magic Rarity Arcana alongside Obducite, making it a multi-resource farm.
• Pro Tip: Use builds with high AoE and mobility to clear Strongrooms quickly. Check the reputation board to prioritize runs when Strongroom rewards are active.
• Best For: Players engaging with Season 9’s Horadric Spellcraft system or those already farming Nightmare Dungeons.

5. Bartering and Caches (Supplementary Method)

• Why It’s Great: Bartering at The Den or turning in Tree of Whispers rewards can yield Masterworking Caches or Greater Material Caches, which sometimes contain 100–300 Obducite. This is not a primary method but supplements other farms.
• How to Farm:
  • Bartering: Trade excess materials or coins at The Den for Masterworking Caches.
• Tree of Whispers: Complete Whispers of the Dead to earn Greater Material Caches, which may include Obducite (though less reliable than direct farming).
• Pro Tip: Use this method when you have downtime or excess resources from other activities.
• Best For: Players with extra materials or those farming Whispers for other rewards.

Season 9-Specific Tips

• Horadric Strongrooms: These new micro-dungeons enhance material farming, especially when combined with Nightmare Dungeons. Prioritize them for Obducite and Arcana.
• Seasonal Ashes: Allocate Ashes to the Obducite drop-rate bonus to boost yields across all activities.
• Seething Opals: Activate these buffs before boss fights or chest openings for +100% item find.
• Build Optimization: Use high-mobility, high-DPS builds like Hydra Sorcerer, Arch Mage Necromancer, or Poison Thorns Spiritborn for faster clears. These builds excel in Season 9’s endgame.
• Group Play: Group farming in Undercity or Hordes significantly increases efficiency. Coordinate with players using complementary builds to cover more ground.

Comparison of Efficiency

• Kurast Undercity (Tribute of Refinement): ~1,000 Obducite/minute (solo, 2-minute runs for 2,000 Obducite). Best for groups with Tributes.
• Nightmare Dungeons: ~633 Obducite/minute (1.75-minute runs for 1,134 Obducite on average). Best for solo or consistent farming
• Infernal Hordes: ~289 Obducite/minute (13-minute runs for 3,760–5,100 Obducite). Best for high-yield bursts with Compasses.
• Horadric Strongrooms: Variable yield, best combined with NMDs for multi-resource farming.

Recommended Strategy

• Primary Method: Focus on Kurast Undercity with Tribute of Refinement if you have Tributes, especially in a group. This is the fastest way to farm Obducite in Season 9.
• Fallback: Run Nightmare Dungeons on Torment 4 with a fast build for consistent Obducite and other materials. Use Horadric Strongrooms when available.
• Supplementary: Use Infernal Hordes when you have Compasses or need boss materials. Barter at The Den or turn in Whispers for extra caches.
• Optimize: Equip a pet, use Seething Opals, allocate Seasonal Ashes, and play on Torment 4 for maximum drop rates.

Notes

• Level Requirement: Obducite only drops after reaching level 60 and on higher difficulties (Torment 1–4).
• Diminishing Returns: Infernal Hordes have diminishing Aether-to-Obducite returns at higher waves, so prioritize shorter, efficient runs.
• Community Feedback: Players on Reddit and forums note that Nightmare Dungeons have become more rewarding in Season 7 and beyond, surpassing Hordes for solo efficiency. Kurast Undercity dominates when Tributes are available.
