In Season 9 of Diablo 4, Resplendent Sparks are a key resource for crafting Mythic Uniques. With drop chances from world bosses being as low as 2.5%, the fastest and most reliable method is crafting—and for that, you need Sparks. This guide outlines solo and group methods to farm them fast and efficiently.
🔥 What Is a Resplendent Spark?
A Resplendent Spark is a crafting material used to make Mythic Uniques at the Blacksmith or Jeweler. They’re rare and account-bound, and each one lets you roll or target a Diablo 4 Mythic item.
You can earn Resplendent Sparks by:
- Completing your Reputation board once per character.
- Completing the Seasonal Journey (1 per account).
- Killing Uber Lilith (1 per account).
- Farming multiple Infernal Horde runs with new alts.
⭐ Best Methods to Farm Resplendent Spark
🧍♂️ Solo Method (Safe & Consistent)
Step 1: Start a New Character (Same Class as Your Main)
- Example: If you are a main Barbarian, create another Barbarian.
- Equip your Seasonal Powers, Pet, Mercenaries, and Outfit.
Step 2: Complete First Seasonal Quest
- Finish “The Embers Yet Smolder” to unlock the Horadric Reputation Board.
- Then complete “The Truths That Lie Within” to activate reputation gain.
Step 3: Farm Aberrant Cinders in Helltides
- Enter Helltide at the top of the hour (e.g., 1:00 PM).
- Aim for 900+ Cinders by level 15.
- Unlock Penitent Difficulty at level 15 for +175% EXP.
- Sprint from chest to chest on your horse. Don’t fight, just loot.
Step 4: Level to 60
- Continue using Helltides, Grim Favors, and Nightmare Dungeons.
- Once strong enough, push harder content like Forgotten Wisdom dungeons.
Step 5: Gear Up with the Main Character’s Loadout
- Transfer full build via stash.
- Equip all gear, skills, Paragon boards, and Seasonal buffs (glyphs optional).
Step 6: Run Infernal Hordes
- Use Infernal Horde Keys.
- Get affixes by killing Elite or Hellborne enemies.
- Elites and Hellbornes grant massive Horadric Knowledge for reputation.
- A single 10-wave run can get you 80% of the board filled.
- Two runs = 1 Resplendent Spark.
Time to Spark: ~45–50 minutes per alt.
👥 Group Method (Fastest)
Step 1: Create a New Character (Same Class)
- Same gear transfer process as the solo method.
- Equip your loadout, Diablo 4 Gold, and seasonal gear.
Step 2: Power Level to 60 with a Friend
- Have a friend run you through fast Pit runs (~1:30 each).
- You don’t need high difficulty. Efficiency > difficulty.
- Get to Level 60 in ~10 minutes.
Step 3: Follow Solo Steps After Level 60
- Equip gear, enter Infernal Hordes, select elite for heavy affixes.
- Finish Reputation Board ➜ 1 Spark.
