Diablo 4 Season 11 Mythic Prankster Nightmare Dungeon Sigils Farm

This method is not a guarantee, but it is currently one of the highest-efficiency ways to maximize your chances of finding a Mythic Prankster Nightmare Dungeon Sigil by massively increasing the number of sigils you see per hour. The core idea is simple, convert boss materials into Outdoor Asmodan chests → flood yourself with Nightmare Sigils → brute-force the Prankster roll.

What is Mythic Prankster in Diablo 4 Season 11?

In simple terms, Mythic Prankster is a special modifier that can appear on Nightmare Dungeon sigils. When active, it guarantees the presence of a unique treasure goblin inside the dungeon — Fancy Old Fedric. This goblin is not a normal loot pinata. Killing him is what makes Mythic Prankster so powerful.

When Fancy Old Fedric is defeated under a Mythic Prankster sigil, the dungeon can shower your entire party with:

• Multiple D4 Mythic Unique items

• A Resplendent Spark

• High-tier Legendary Runes

• Additional endgame loot, scaled to Torment 4

Core Requirements of D4 Mythic Prankster Sigil Farm

Difficulty - Torment 4 (mandatory). Seasonal Essences (VERY IMPORTANT) - You must have both at max rank (Rank 5).

• Essence of Hellfire

• Essence of Sin

Correct Setup:

General farming:

Hellfire → Purified slot

Sin → Corrupted slot

Outdoor Asmodan fight: Swap → Sin in Purified, Hellfire in Corrupted. This directly affects Nightmare Sigil drops from chests.

How to Farm D4 Mythic Prankster in Season 11?

Step 1: Initial Living Steel Setup

Farm ~200 Living Steel from Helltide chests. This is the only manual Living Steel farm you need. The loop becomes self-sustaining afterward.

Step 2: Farm Grigo (Living Steel → Agony Loop)

Spend Living Steel to open Grigo chests. Cost: 12 Living Steel per chest.

Rewards:

• Shards of Agony

• Stygian Stones

• Chance for Bile ambush (huge bonus)

Why Grigo? Because:

Shards of Agony → Duriel

Duriel → Corrupted Horns

Corrupted Horns → Outdoor Asmodan chests

Step 3: Duriel – Convert Agony into Horns

3 Shards of Agony = 1 Duriel chest. Each chest gives 3 Corrupted Horns of Duriel. From ~16 shards: ≈ 15 Corrupted Horns.

Step 4: Outdoor Asmodan (FIRST CHEST OPENING)

South of Zarbinzet

Before fighting:

Swap Essences

Sin → Purified

Hellfire → Corrupted

Chest Costs

5 Corrupted Horns per Duriel chest

15 Horns = 3 chest opens

What You Get

Each chest can drop: ~40 Living Steel or ~30 Exquisite Blood. Large batches of Nightmare Dungeon Sigils ← THIS IS THE POINT

Step 5: Expand the Loop (Multi-Boss Farming)

Using materials gained:

Boss Targets

Grigo → More Agony + Stygian Stones

Lord Zir (Exquisite Blood) → Pin Cushion Dolls

Bile (Betrayer’s Husks) → Corrupted Eyes

Conversions

Pin Cushion Dolls → Andariel Cloth

Betrayer’s Husks → Corrupted Eyes of Bile

Stygian Stones → Shards of Agony (Always do this)

Do NOT waste Stygian Stones on anything else.

Step 6: Outdoor Asmodan (FULL CHEST DUMP)

Return to Outdoor Asmodan and open:

Duriel chests (Horns)

Andariel chests (Cloth)

Bile chests (Eyes)

With Essence of Sin in Purified slot. This is where you see hundreds of Nightmare Sigils and mass-roll for Mythic Prankster.

Step 7: Sigil Handling (CRITICAL – Don’t Lose Them)

Pick up one inventory of sigils. Check each for Mythic Prankster affix. Drop checked sigils away from the chest. DO NOT teleport to town immediately. You can lose un-checked sigils. Once checked Salvage at Occultist → Sigil Powder.

Step 8: Craft Sigils (Hidden Power Step)

Use Sigil Powder at the Occultist. Craft Nightmare Dungeon Sigils. Check each batch. Salvage and repeat if needed. This adds dozens more rolls per cycle.

Extra Optimizations

World Boss > Everything. Always do them if up. Free Nightmare Sigils.

Goblin Events

Keep Treasure Breach sigils. Legendary Sigils can be saved or salvaged based on preference.

Expected Results (Reality Check)

Community average: ~1 Mythic Prankster per ~500 sigils. This method lets you check hundreds of sigils in ~1–2 hours. Example result: Mythic Prankster obtained in ~1.5 hours (lucky, but realistic).
