Why Runes Are Non-Negotiable in Diablo 4 Items the Endgame
Crafting Mythic gear - the pinnacle of item progression in Diablo 4 - demands:
2 Resplendent Sparks
6 Magic Runes
6 Rare Runes
6 Legendary Runes
These materials are challenging to accumulate, especially Legendary Runes, which are gated behind high-difficulty activities and advanced tribute rewards. Because of this, Undercity farming becomes the cornerstone of high-end character optimization.
Without Runes, players are essentially locked out of:
Top-tier Mythic item crafting.
Max-performance builds in competitive content.
Access to the strongest passive and active buffs.
Broader Gameplay Benefits
Breaks up monotony by adding badly needed boss diversity in the Greater tier.
Justifies more build experimentation, as players would need resistances/mechanics tuned to Elias, not just poison/physical for Duriel.
Injects fresh lore relevance into Season 9 without building a boss from scratch.
Gives Necromancer and caster fans a strong thematic opponent while expanding on the Horadrim betrayal story.
Lore Justification: Elias Isn't Finished
Elias's entire arc in the campaign revolves around his immortality, obsession with Lilith, and twisted desire to reshape Sanctuary under the Triune's teachings. Players only temporarily cripple him - never truly destroy him. He must reconstitute somewhere, plotting revenge as he rebuilds his magical arsenal. Lore hints suggest Elias can only be permanently slain if his original Horadric sigil is shattered, something the player never confirms doing.
This makes Elias' reappearance not just sensible - it fills in story gaps and builds hype for Diablo 4's 2026 expansion (where the Horadrim storyline is expected to explode again).
Final Thoughts: Why This Route Reigns Supreme
In a season loaded with new mechanics and challenges, efficiency is everything - and Kurast Undercity with Tribute of Harmony delivers just that. It rewards players who are already investing time in Nightmare Dungeons by giving them a way to convert that effort into powerful crafting materials that matter.
Other methods can supplement Rune farming, but none match the guaranteed consistency, scalability, and direct synergy with build progression that this route offers.
If you're serious about pushing builds to buy Diablo IV Items their limits in Diablo 4 Season 9, this is one farming strategy you cannot afford to ignore.
