Core Crafting Materials: Forgotten Souls, Obducite, and More
This section explains which materials the player needs, why they matter, and the most efficient ways to obtain them for endgame upgrades and crafting. It highlights where to prioritize runs and which activities scale best with difficulty.
Forgotten Souls: Uses and Acquisition
Forgotten Souls serve as a rare upgrade currency for Enchanting, Masterworking, and improving Ancestral Legendary items. They are consumed when imprinting aspects, enchanting affixes, or converting Ancestral gear through the Blacksmith and Occultist. Players should reserve Souls for target enchants on endgame pieces rather than bulk spending on minor upgrades.
Primary sources: salvaging Ancestral Legendaries, Helltides (Tormented rewards and Tortured Gift Chests), Legion Events, Infernal Hordes, and certain Kurast Undercity rewards. Salvage rates rise with higher difficulty tiers and specific content like Tribute of Titans runs. Farming tip: prioritize activities that drop Ancestral or high-rarity gear—these yield the most Souls per hour. Crafting economy note: stockpiling Souls before major Season 11 tempering shifts helps avoid wasteful spending.
Obducite: The Key to Masterworking
Obducite is required for Masterworking gear, unlocking powerful stat bonuses and enabling subsequent Tempering steps. Season 11 rework made Obducite central to progression; Masterworking now often precedes Aspect Imprinting or further Tempering, so players should target reliable Obducite sources.
Best sources: Nightmare Dungeons, Infernal Hordes, and Kurast Undercity Tributes. Nightmare Dungeons offer high Obducite per run for fast AOE builds, while Infernal Hordes give additional Greater Affix chances from end chests—useful when chasing Legendary upgrades. Kurast excels in group play for steady drop rates. Players should run content at Torment 4+ because reward scaling increases Obducite, Forgotten Souls, and Murmuring Obols yield. Carrying shard/veiled crystal stack limits and running with Forgotten Wisdom or Horadric affix reserves increases efficiency.
Nightmare Dungeon Sigils and Supporting Materials
Nightmare Dungeon Sigils function as entry rewards and currency for Syndicate-like rewards and are essential for certain endgame recipes and Sigil Powder crafting. Sigils also tie into Nightmare Dungeon-specific drops like Distilled Fear and Veiled Crystals that support Enchanting and Tempering. Players targeting Sigils should focus on higher-level Nightmare Dungeons where sigil quantity and quality scale with difficulty.
Supporting materials to track: Sigil Powder (conversion material), Murmuring Obols (vendor/craft currency), Living Steel and Exquisite Blood for high-tier tempering, and Forgotten Wisdom affixes that improve drop tables. For efficient farming, combine Nightmare runs with Helltides and Infernal Hordes when available; this stacks opportunities for Sigils, Obducite, and Forgotten Souls in a single play loop. Keep an eye on Tribute of Titans and Kurast events for grouped rewards that often include Sigils and higher rates of Legendary or Mythic Unique drops.
Optimal Farming Loops and Material Management
This section explains which activities yield the most of each key material and how to chain them into repeatable loops. It highlights where to prioritize Obducite, Forgotten Souls, sigils, and high-loot encounters so players can plan runs by time investment and party size.
Efficient Material Farming Activities
Nightmare dungeons, Infernal Hordes, and Kurast Undercity tributes each target different materials. Nightmare dungeons give steady Obducite and Distilled Fear with low setup time; they suit fast AOE builds and solo pit runs. Infernal Hordes reward large chests at the end that spike Greater Affix and Obducite, making them valuable when seeking both crafting mats and gear upgrades. Kurast Undercity tributes (Tribute of Refinement) scale well for groups and provide high Obducite per hour if the party clears efficiently.
Use a prioritized route: start with a quick Nightmare dungeon when alone, switch to Infernal Hordes for chest-focused loops, and run Undercity tributes with a coordinated group. Track time-per-run and average drops to decide which to repeat.
Strongroom and Treasure Breach Optimization
Horadric Strongroom and Treasure Breach affixes directly impact loot density. Aim for Nightmare dungeon affixes like Horadric Strongroom, Treasure Breach, and Material Reserve Sigils to increase Horadric materials, Obducite, and gold. When the strongroom appears, slow down to clear all connected rooms and open chests to maximize Greater Affix chances.
Use the following checklist during runs:
- Prioritize routes that hit the strongroom first.
- Save movement and consumables for opening chests.
- Clear Treasure Breaches fully; they often contain multiple whisper caches and rare items.
For efficiency, reroll or avoid dungeons without those affixes unless they are much faster to clear. Keep an eye on Whisper Caches and hidden armory nightmare dungeons for bonus drops and unique loot pools.
Sigil Crafting, Management, and Salvaging
Nightmare Sigils and material reserve sigils determine access to specific rewards. Craft or carry sigils that boost Obducite, Forgotten Souls, or Horadric materials depending on the immediate goal. Salvaging priorities: save high-rarity uniques and mythic uniques for tempering rerolls and masterworking; salvage lower-tier gear for Forgotten Souls and crafting scraps.
Manage sigils with a simple rotation:
- Use material reserve sigils on long farms to stack resources.
- Keep nightmare sigils for targeted runs where specific boss loot matters.
- Salvage duplicates and common uniques immediately to free inventory and convert into Forgotten Souls.
Whisper caches, Grim Favors, and Treasure Goblins should be looted when present; they often drop sigils, rare crafting components, or small caches that compound over a farming loop.
Loot-Heavy Content and Group Scaling Strategies
Loot-heavy content scales well with party size but requires coordination. Kurast Undercity tributes and Legion Events give superior drops in full groups; they also increase Obducite and chance for Ancients or mythic uniques. Infernal Hordes remain challenging but reward a large chest with higher Greater Affix probability—best run with strong group AOE and pull control.
Use party-scaling rules to assign roles:
- One player focuses on ripping packs and triggering event spawns.
- One player clears strongrooms, chests, and whisper caches.
- One player kites or holds dangerous bosses like Andariel/Duriel/Beli’al to protect clear speed.
Adjust the loop: alternate a PTR-sized Infernal Horde or Undercity tribute with 2–3 Nightmare dungeons to reset destructible respawns and maintain consistent resource intake. Track drop rates per hour and switch to solo pit runs (hidden armory or Pit runs) when speed matters more than absolute loot density.
