How to Farm Legendary Runes Fast in Diablo IV Season 10

Oct-08-2025

 

Legendary Runes are some of the rarest and most powerful crafting materials in Diablo IV Season 10. They're essential for upgrading high-end gear, rerolling affixes, and preparing for the upcoming Mythic crafting system. But for most players, rune drops can feel painfully slow — especially when farming random mobs or world bosses.

 

Luckily, there's a faster and more reliable method that top players are using this season: Kurast Undercity + Tribute of Harmony route.

 

 

The Best Rune Farming Spot: Kurast Undercity

If you own the Vessel of Hatred expansion, you can access the Kurast Undercity, one of the most rewarding endgame dungeons in Season 10.

 

Inside, you'll find a Spirit Brazier — a unique feature that allows you to offer Tributes before starting your run.

 

When you offer a Tribute of Harmony, it greatly increases your chances of earning Rare and Legendary Runes once you complete the dungeon and defeat the final boss.

 

This makes the Kurast Undercity the most efficient way to farm Legendary Runes right now.

 

How to Farm Legendary Runes Step by Step

1. Collect Tributes of Harmony

You'll need Tributes before starting your Undercity run. These can drop from:

 

The Pit (from final bosses on higher tiers)

Whisper Caches, especially Dungeon Key Caches on Torment IV

Treasure Goblins (Glittering Prisms) with guaranteed Tribute drops at higher difficulties

 

The more Tributes you collect, the bigger your rune payout later.

 

2. Activate the Kurast Brazier

Head into the Undercity and interact with the brazier. Offer your Tributes of Harmony to begin your rune farming session.

 

When you complete the dungeon and defeat the final boss, you'll receive a large bundle of runes — often including Legendary-quality ones.

 

Tip: The more Tributes you offer, the higher the rune yield at the end.

 

3. Run Efficiently

Speed and consistency matter. Clear each section quickly, maintain a good Attunement level, and aim for clean boss kills.

 

Each complete run can reward multiple runes, making it far more efficient than random open-world farming.

 

Why Tribute Farming Is So Effective

Unlike random drops, the Tribute of Harmony method guarantees steady rune progress. Each completed Undercity run gives you tangible rewards — not just a chance at loot. That means even if RNG isn't on your side, you're still building toward consistent gains.

 

Players report earning dozens of rare and several legendary runes per hour when running Kurast Undercity efficiently on higher difficulties.

 

It's repeatable, fast, and scales perfectly with your Tribute investment — everything a reliable farming method should be.

 

Bonus Tip — Transmute Runes at the Jeweler

Don't ignore your lower-tier runes! Visit any Jeweler to combine and upgrade them:

 

1. Combine three identical Rare Runes.

2. You'll receive one new rune, with about a 15% chance to become Legendary.

 

This system helps you turn excess rares from your Tribute runs into even more valuable crafting materials.

 

Final Thoughts

If you'd rather skip the grind altogether, mmoso offers Rune trading — but farming them yourself through Kurast Undercity is still the fastest and most reliable way to farm Legendary Runes in Diablo IV Season 10.
