In the ever-evolving world of Diablo 4 Gold, Season 4 has introduced one of the most rewarding and intricate systems yet—infinite Mythic crafting. Alongside it, we now have new mechanics for Spectral Ash, Unveiler’s Oath Reputation, and various types of caches that can significantly impact your gear and gold farming strategies.
In this deep dive, we’ll explore:
How infinite Mythic crafting works
The role of Spectral Ash and Scrolls
How to get Sparks for Mythic items
Cache comparison: Whispering Tree vs. Seasonal Greater
Best practices for farming efficiently
Let’s break it all down.
Understanding the Core Mechanics: Spectral Ash, Scrolls, and Sparks
Before diving into the grind, it's important to clarify the key components involved in Mythic crafting this season.
Spectral Ash
The primary currency for purchasing Oath Scrolls.
Oath Scrolls are essential for leveling up your Unveiler’s Oath Reputation.
Unveiler’s Oath Reputation
Grants reward caches, which contain valuable gear and Sparks—the key component required for crafting Mythic items.
To farm efficiently, you’ll need to focus on sources that provide both Spectral Ash and reputation.
Where to Farm Spectral Ash and Reputation
Here’s a breakdown of the best farming activities, categorized by Ash and reputation yields:
Spectral Ash Sources
Seasonal event (with Belial summon): ~430 Ash total
150 from the event, 270 from Belial
Uber Bosses (excluding Belial): ~170 Ash each
Belial (in his own lair): ~700 Ash
Belial (auto-summoned after any Uber kill): ~700 Ash
Note: These are the only reliable Ash sources this season.
Reputation Sources
Kurast UnderCity boss & Lord in Horde: 3,600 Rep
Maiden in Helltide & Varshan/Zir (except Belial): 4,800 Rep
Belial (post-Uber): 7,200 Rep
World Boss: 9,600 Rep
Belial (in his lair): 12,000 Rep
Important: Tree of Whispers and Legion caches give zero Ash and zero reputation—avoid them if you're farming for Mythics.
The Mythic Crafting Loop: Step-by-Step
Once you’ve gathered enough Ash, here’s how to begin the infinite Mythic crafting loop:
Cost: 250 Ash each, totaling 14,750 Ash
Can be bought from the vendor in Tarsarak
Set difficulty: Normal
Choose a simple name for easy deletion later
Assign only Varshan's Power in the seasonal menu
Invest points into Frozen Orb and Teleport (thanks to Renown)
Ride to the first quest marker and speed through dialogue
Enter the nearby Crypt, kill the mob, and continue
Finish the sequence to unlock seasonal interaction with the NPC in Tarsarak
Speak to the seasonal NPC, check your objective
Use all 59 Scrolls (each grants 6,000 reputation)
This unlocks all seasonal reward caches up to the 18th, which includes the Spark
Even on Normal difficulty and with low-level characters, caches drop:
800+ item power gear
Greater Affixes (2+ per item, minimum)
Legendary and Unique items
This is a great way to get usable gear or items to upgrade aspects, which becomes rare after Paragon 260.
Don’t forget to stash boss summoning mats before deleting the character.
Delete the character
Create a new one
Repeat the entire process (approx. 9.5 minutes per run)
Pro Tips and Limitations
New characters cannot buy Scrolls unless they've completed the seasonal questline.
A low-level Sorcerer can open Sorceress-obtained caches from stash; cross-class compatibility does not apply.
Seasonal caches do not give XP, so to level new characters, use Whispering Tree caches—you'll need 29 to hit level 60.
If you’re looking to optimize materials like gold, recipes, aspects, and gear, check the previous season’s breakdown, where 100 Whispering Tree caches were opened and analyzed.
Crafting Mythic Items: Two Options
Once you've collected enough Sparks, you have two paths:
Option 1: Random Mythic Craft
Done at the Blacksmith
Requires 2 Sparks + 50 million gold
Option 2: Specific Mythic Craft
Done at the Jeweler
Requires runes, which can be:
Farmed (with effort)
Bought via Diablo trade marketplace
A separate video guide is coming soon detailing the economic side of trading, farming, and value of runes.
Cache Comparison: Whispering Tree vs. Seasonal Greater
Let’s compare 33 Whispering Tree Caches and 33 Seasonal Greater Caches, based on actual game data from a 250+ Paragon character.
Whispering Tree Caches
Gold earned: 169 million (~5.1 million per cache)
Loot highlights:
1 staff with triple Greater Affixes
Several Runes
Some Uber Boss materials
3 Mythic-related Tribute mats
5 Aspect upgrades from salvaging
Seasonal Greater Caches
Gold earned: 138 million (~4.2 million per cache)
Loot highlights:
Far more Greater Affixes
High-quality gear, including offhands for alt builds
No runes, no XP, no materials
Conclusion: Whispering Tree caches offer better variety and utility—runes, XP, materials, and gold. Seasonal caches shine when it comes to gear quality, especially Greater Affix density.
Final Thoughts: What’s the Best Path?
Whether you’re trying to maximize your gold, craft perfect Mythics, or optimize seasonal rewards, the system is designed to let you choose your grind.
Want pure gear and Sparks? Focus on Seasonal caches via the infinite crafting loop.
Looking to level alts, gather materials, or upgrade aspects? Stick with Whispering Tree runs.
For maximum efficiency, rotate both strategies and tailor based on your character’s progress.
With each loop taking less than 10 minutes and the possibility to infinitely repeat, this season rewards players who plan, optimize, and execute smartly.
