Diablo 4 Season 9 introduces Horadric Spells, a powerful new customization system that lets players enhance their abilities with unique modifiers. These spells are built from multiple components that must be discovered and upgraded—requiring dedicated grinding to maximize their potential.
One of the most efficient ways to farm these upgrades is by locating Horadric Strongrooms, special challenge dungeons that reward players with essential crafting materials. This guide explains how to find Horadric Strongrooms, optimize your runs, and secure the best rewards for upgrading your spells.
How to Find Horadric Strongrooms in Diablo 4
Horadric Strongrooms appear randomly within Nightmare Dungeons, with higher difficulties increasing their spawn rate. However, even on lower tiers, they appear frequently enough to make farming them worthwhile.
Locating the Strongroom Pedestal
-
Strongrooms are accessed via a pedestal, usually found in the first section of a Nightmare Dungeon.
-
Interacting with it opens a portal, transporting you to a mini-dungeon separate from the main Nightmare Dungeon.
-
After completing the Strongroom, you can exit the Nightmare Dungeon immediately—though finishing it grants additional XP and seasonal progress.
How Horadric Strongrooms Work
Each Strongroom follows the same structure:
Clear the Initial Room – Defeat all enemies to proceed.
Activate Modifiers – Choose buffs or challenges that affect the next phase.
100-Second Timer Starts – Kill as many enemies as possible to increase your Attunement (score).
Boss Spawns – Defeating it grants rewards based on your Attunement rank.
Key Mechanics to Maximize Rewards
-
Speed is Critical – More kills = higher Attunement = better loot.
-
Dying Costs Time – You can respawn, but lost seconds hurt your score.
-
Shrines Provide Buffs – Use them strategically to boost efficiency.
-
Difficulty Affects Rewards – Lower tiers make enemies easier but reduce loot quality.
Best Rewards from Horadric Strongrooms
Successfully clearing Strongrooms grants:
-
Horadric Phials (crafting currency)
-
Horadric Knowledge (unlocks spell upgrades)
-
Spell Modifiers (enhance your Horadric Spells)
The higher your Attunement rank, the better the rewards—making speed and efficiency crucial.
Optimizing Your Horadric Strongroom Runs
To farm efficiently:
✔ Prioritize High-Difficulty Runs – More rewards per clear.
✔ Use AoE & Mobility Skills – Maximize kill counts before the timer ends.
✔ Activate Shrines Early – Boost damage or movement speed for faster clears.
✔ Group Up – Coordinated teams can clear faster than solo players.
Final Thoughts: Are Horadric Strongrooms Worth It?
If you’re pursuing Horadric Spells in Diablo 4 Season 9, Strongrooms are a must-farm activity. While they demand fast-paced combat, the rewards significantly enhance your build’s power.
For the best results, focus on speed, efficiency, and high-tier Nightmare Dungeons—ensuring you get the most out of every run.
