Diablo IV Season 11: The Fast Farming Loop for Goblin Sigils, Neathiron, Scrolls, and Mythics
Build a closed-loop route that feeds boss keys into Azmodan chests, then turns sigils into the resources you actually need for endgame crafting.
Overview
Diablo IV Season 11 resource farming, simplified
Season 11’s endgame economy is less about hunting one perfect activity and more about running a loop that constantly refills itself. If you want Scrolls of Restoration, Neathiron, Obducite, socket materials, and a steady flow of Mythic items, the most consistent backbone is still Goblin Sigils—specifically Treasure Breach—supported by Azmodan’s chests and boss-key farming.
This guide breaks down the core loop, where each piece comes from, and the decision points that stop you from wasting time (and crafting resources) on low-impact rerolls.
The Season 11 “everything drops here” core: Goblin Sigils (Treasure Breach)
If you only remember one thing, remember this: Treasure Breach Goblin Sigils are the season’s most efficient “catch-all” source for a wide spread of materials. They’re where you cover most recurring needs—especially the stuff you burn while pushing item power 800 upgrades and masterworking.
Why Treasure Breach is the centerpiece
- Broad loot table: materials, crafting resources, and general progression items all show up in meaningful volume.
- Scales well with group play: rotations multiply value without increasing cost.
- Solves multiple bottlenecks at once: instead of farming one resource at a time, you refill several.
How to get Goblin Sigils consistently
You’ll see Treasure Breach sigils from multiple sources, but the steady pipeline comes from the same “key into chest into sigil” chain described later in this guide.
- World Bosses: reliable source of sigils and related seasonal drops.
- Azmodan’s Chests: one of the best volume sources for sigils over time.
- Occultist crafting: you can craft sigils using Sigil Powder (details below).
Party rotations: the simplest multiplier in the season
When a sigil can be consumed by one player to open an activity, rotations are pure efficiency. If four players each bring one Treasure Breach sigil, you can run four breaches back-to-back—effectively turning one sigil into four runs worth of results for the group.
This is especially important if you’re trying to stockpile materials for repeated masterworking attempts, or if you’re chasing Mythic drops via complementary sigils like Mythic Prankster.
Sigil Powder: crafting, salvaging, and what’s worth keeping
Sigil management matters because Season 11 can drown you in low-value sigils. The goal is to turn “trash” into more rolls at the sigils you actually want.
How Sigil Powder works
- Salvaging sigils yields Sigil Powder.
- Per the source loop: each salvaged sigil grants 15 powder.
- Crafting a sigil costs 60 powder.
The practical approach
Most players should treat this as a simple filter:
- Keep: Treasure Breach sigils and (rarely) Mythic Prankster sigils.
- Salvage: everything else you don’t plan to run.
- Craft: when you have enough powder, craft more sigils and keep cycling until you hit the ones that matter.
Treasure Breach craft odds
When crafting, expect Treasure Breach to appear at roughly 1 in 40. That’s not “rare,” but it’s also not something you’ll hit instantly—so salvaging excess sigils to keep the loop moving is the intended play pattern.
Scrolls of Restoration: how to stop running out
Scrolls of Restoration become a problem when you treat every item like it deserves endless tempering attempts. The easiest way to “farm” Scrolls is actually to spend them smarter.
Don’t fish Greater Affixes on everything
The guide logic is simple: only “go hard” on tempering when the base item is already worth it.
- Greater Affix tempering is only available on item power 800 gear.
- At lower item power (for example 750), you’re not even eligible for that top-end outcome.
- A Greater Affix represents a boosted roll (described in the source as roughly 1.5× the maximum value).
Which items deserve Scroll investment
A strong, resource-safe rule is:
- Only fish for Greater Affix tempering on item power 800 pieces that already have three or more stats you want.
- Expect that to be a minority of drops (the source estimates around 20%).
Where Scrolls of Restoration drop
Scrolls can show up from general play, with notable mentions:
- The Pit (occasional drops)
- Kurast Undercity (occasional drops)
- Other random sources depending on your activity mix
- Guaranteed from certain activities like the Citadel and the Horde (if you choose to run them)
Mythic items and Sparks: what to farm and why
Season 11 Mythics are no longer restricted to a tiny set of sources. The key rule is difficulty: Mythics can drop from any activity on Torment 1 or higher. That means your best Mythic strategy is to pick the activity loop that also refills your other needs (sigils, keys, Neathiron), rather than tunnel-visioning one boss.
How Sparks are obtained
- Seasonal Journey rewards
- Salvaging Mythic items (turning extra drops into progress)

Useful Mythic drop rates and sources (from the source material)
- Uber Bosses: about 3%
- Kurast Undercity with a Mythic Tribute: about 30%
- Azmodan’s Chest: about 5% chance for a Mythic
Mythic Prankster: the high-value Nightmare Dungeon sigil
The most profitable targeted Mythic approach described is the Mythic Prankster Nightmare Dungeon sigil.
- It drops from World Bosses and Azmodan’s Chests at roughly 1 per 500 sigils.
- It can also be crafted at the Occultist at a similar rate.
- Like Treasure Breach, it benefits enormously from party rotations.
Important Mythic Aspect rule: stacking behavior
Mythic Aspects have a special interaction:
- Two Mythic Aspects can work simultaneously.
- A third Mythic Aspect will not add additional effect.
- Duplicate Legendary Aspects do not stack (only one applies).
Gambling can drop Mythics (and the item type can surprise you)
Because “any activity” includes gambling, Mythics can appear from gambling outcomes. Also, the Mythic you receive can be a different slot than what you gambled for (for example, gambling boots can result in a Mythic helmet). Treat this as a bonus stream, not a primary plan.
Neathiron: what it’s for and where it actually comes from
Neathiron is a true endgame bottleneck if you’re pushing perfect masterworking outcomes.
Why you need Neathiron
- Used to reach the Greater Affix property tied to deep masterworking progression (the source references the 25th roll at the Blacksmith).
- Also used to change that Greater Affix outcome if you hit something that doesn’t fit your build.
Main Neathiron sources
- Treasure Breach sigils (primary)
- Whisper Tree caches (occasional)
- Legion events (occasional)
- World Bosses: can drop it, with a special note below
Belial as the reliable drip
Belial stands out:
- From most world bosses, Neathiron is occasional.
- From Belial, it is described as a consistent drop of about 1 to 3 Neathiron.
Azmodan’s Chests and boss keys: the closed-loop engine
The most important structural idea in the source is that Season 11 farming works best as a closed loop. You don’t just “farm sigils.” You farm the keys that open the chests that drop the sigils that then generate the materials that help you farm faster.
Step 1: reach Torment 1, then prioritize boss keys
Once you’re in Torment 1, start treating boss keys as your entry ticket to the entire system.
Where boss keys come from
- Helltide
- Whisper Tree chests/caches
- Kurast Tributes that reward boss keys
- Boss-key chests in the Mercenaries den
- Azmodan’s Chests (which is why the loop sustains itself)
Step 2: lesser bosses feed higher-tier boss access
The loop escalates naturally:
- Keys from the above activities lead to lesser bosses.
- Killing those bosses provides keys for higher-rank Ubers.
- After rank 1 and 2 Ubers, Belial’s Shadow can appear and drop keys for Belial himself.
Step 3: convert boss kills into Azmodan chest keys (Essences)
The source highlights a key conversion rate:
- You’ll want to kill Andariel and Duriel in their lairs multiple times because each kill grants 3 keys for their Azmodan chest.
- Killing Belial grants 5 keys for an Azmodan chest.

Step 4: open the right chests (and why)
Not all chest openings are equal. The source’s approach prioritizes the side chests:
- Open the left and right chests.
- The central Azmodan chest is often skipped because its loot is described as poorer, while the chance to trigger a “waterfall” of sigils is not exclusive to any specific chest type.
The “waterfall” of Nightmare Dungeon sigils
A defining payoff of Azmodan chest farming is the mass sigil drop:
- Approximately every third chest can drop 80 to 120 Nightmare Dungeon sigils.
- Within that flood, you should reliably see some Treasure Breach sigils and, rarely, Mythic Prankster.
Azmodan’s Strength rank affects drops
The quantity and quality of sigils and Kurast Tributes is heavily influenced by your seasonal progression—specifically the Azmodan’s Strength rank, which is leveled through Azmodan-related play. If your chest results feel “dry,” improving that rank is one of the few levers that can change your average outcomes over time.
Kurast Undercity Tributes: the targeted Mythic option
If you want a more targeted Mythic route than “anything can drop anywhere,” Kurast Undercity’s Mythic Tribute is the standout in the source.
- Mythic Tribute runs are described at around 30% Mythic chance.
- Tributes themselves drop in large quantity from World Bosses and Azmodan’s Chests.
Gold and runes: when they matter (and when they don’t)
For most players in Season 11, gold and runes aren’t the limiting factor unless you decide to mass-roll expensive affixes at the Occultist.
- Gold becomes relevant if you repeatedly chase specific high-tier affix outcomes at scale.
- Runes are less valuable when Mythics are dropping frequently, since many rune-heavy crafts are Mythic-adjacent.
Putting it together: an optimal weekly rhythm
To keep the loop healthy (and avoid burning out), rotate through activities that feed keys and chests while sprinkling in your best-value sigils.
Recommended loop (high level)
- Helltide + Whispers for steady key generation
- Boss chain to convert keys into higher-tier access and Azmodan chest Essences
- Azmodan side chests to generate large stacks of Nightmare Dungeon sigils and Tributes
- Treasure Breach to refill materials (including Neathiron coverage and crafting resources)
- Kurast Undercity Mythic Tribute when you specifically want Mythic volume
- Belial when you need reliable Neathiron on top of general loot
Why diversification is part of efficiency
Even if one activity is slightly better on paper, rotating content prevents bottlenecks (keys, Essences, sigils, or specific materials) and keeps your seasonal ranks and drop modifiers progressing. Season 11 rewards players who touch multiple systems rather than sitting in only one mode.
Frequently Asked Questions
Do Mythic items really drop from any activity in Season 11?
Yes—per the season rules referenced here, Mythics can drop from any activity as long as you’re on Torment 1 or higher. Targeted sources (like Mythic Tributes) simply raise your odds.
What’s the best use of Scrolls of Restoration if I’m always short?
Stop trying to force perfect tempering on every piece. Save Scroll-heavy attempts for item power 800 items that already have multiple ideal stats, then accept “good enough” rolls on the rest.
Is Treasure Breach still worth running if I only care about Neathiron?
Yes. It’s described as the main source for Neathiron while also covering other crafting materials you’ll need anyway, which makes it more efficient than single-resource farming.
How do I increase the number of sigils I get from Azmodan chests?
Improve your seasonal progression tied to Azmodan’s Strength and keep feeding the chest loop with Essences from boss kills. The biggest spikes come from the occasional mass sigil drops.
Can I run more than one Mythic Aspect at a time?
Two Mythic Aspects can function simultaneously, but a third will not. Also, duplicate Legendary Aspects won’t stack—only one instance applies.
