Whether you're pushing leaderboards, chasing Uber Uniques, or leveling your Glyphs for The Pit, mastering Strongroom runs is essential.

This article breaks down the best strategy and build for Strongroom farming in Season 9, including dungeon mechanics, layout tips, build optimization, and key farming routes to help you dominate this activity.

What Are Strongrooms in Season 9?

Strongrooms are a new dungeon variant introduced in Season 9, offering compact layouts, elite-heavy packs, and valuable rewards like Obelisks, rare loot, Glyph XP, and Whisper progress. These rooms are designed to be cleared fast and repeated often, making them perfect for loot-focused grinding.

They often feature:

Tight corridors and fast pacing.

Multiple Elites packed together.

Locked chests and Obelisks with optional mini-objectives.

High mob density, ideal for AoE-heavy builds.

Why Farm Strongrooms?

Strongrooms are one of the best endgame content loops for:

Glyph XP – You can clear 5+ Strongrooms in the time it takes to do a single Nightmare Dungeon.

Loot Efficiency – Elites drop high-quality loot, and the Strongroom chests often drop Sacred or Ancestral Legendaries.

Seasonal Materials – Whisper progress, crafting mats, and currency drops make them ideal for seasonal objectives.

High Mob Density – Ideal for builds focused on area-of-effect (AoE) and resource generation.

Strongroom Farming Strategy

1. Choose Efficient Routes

You’ll want to stack Strongrooms in high-density areas. Recommended locations:

Scosglen – Easy-to-navigate layout, excellent Elite density.

Dry Steppes – Quick teleport routes to multiple Strongrooms.

Hawezar – Slightly more winding, but high loot return.

Pro tip: Use the Tree of Whispers to mark Strongrooms for Whisper completions while farming loot.

2. Reset Dungeons Efficiently

After each Strongroom run, exit the dungeon and use the Leave Dungeon option or fast travel to reset it. If you're partied up, one player can leave while others stay, rotating reset duties.

3. Focus on Elite Packs

Speed Rogues and other strong AoE builds shine when focusing on clustered elites. Don’t waste time clearing scattered mobs; pull them together, pop Imbuements, and detonate them quickly.

4. Obelisk Buffs Matter

Strongrooms often contain Obelisks that provide temporary buffs:

Increased damage

Movement speed

Reduced cooldowns

Bonus loot from chests

These can significantly accelerate your farming run. Make sure to interact with them ASAP before engaging large packs.

5. Watch the Timer

Strongrooms sometimes contain timed chests that require clearing a room within a set time limit. Use your mobility skills (like Dash or Shadow Step) to get to enemies fast and eliminate them quickly. Don’t waste time looting until after the chest timer is complete.

Alternative Builds for Strongroom Farming

While the Speed Rogue is ideal, other builds are also very effective:

Ball Lightning Sorcerer

Teleport + Flame Shield mobility.

Huge AoE coverage.

Glyph leveling powerhouse.

Whirlwind Barbarian

Tanky and fast.

Great at clearing dense packs.

Less reliant on timing windows.

Shred Druid

Excellent with Nature’s Fury.

Shred mobility clears small dungeons quickly.

Effective with Obelisk buffs.

Blood Lance Necromancer

Elite-focused and can clear mobs quickly.

Slightly slower movement than Rogue or Sorc, but powerful burst.

Tips for Strongroom Mastery

Group Farming – Consider grouping up with friends to split reset duties and clear faster.

Stack Whispers – Combine Whisper objectives with Strongroom locations to double dip.

Nightmare Sigils – Use Strongroom runs to level glyphs fast before pushing harder Nightmare dungeons.

Avoid Overkill – Don't over-invest in single target damage; AoE and mobility matter most.

Loot Filter – Mark high-priority items to avoid wasting time with inventory management.

Conclusion

Strongrooms are one of the best additions in Diablo 4 Season 9 for players who want a fast-paced, loot-heavy farming experience. Whether you're chasing glyph XP, seasonal rewards, or just want fast action, running Strongrooms with an optimized build like the Speed Shadow Rogue can skyrocket your efficiency.

Remember to plan your routes, focus on elites, and use Obelisks and buffs to your advantage. With the right build and mindset, you'll be raking in legendaries, glyph levels,Diablo 4 Items for sale and crafting materials in no time.
