How to Farm Arcana in Diablo 4 Season 9

Even with the current low drop rate, there are still methods you can use to Diablo 4 Items increase your chances of finding Arcana.

1. Strongroom Reset Trick (Risky)

Players have found that logging in and out repeatedly to reset dungeons can increase Arcana farming rates by generating more Strongroom opportunities.

Warning: This method has already led to temporary suspensions and bans. Use at your own risk.
Blizzard has not formally allowed or banned this strategy, but its excessive use has drawn their attention.

2. Farm Horadric Strongrooms (The Legit Way)

The best legitimate method is to use Nightmare Sigils with the "Horadric Strongroom" affix. This guarantees a Strongroom within the dungeon, and finishing the wave-based encounter gives you a chance at Arcana.

Use AoE-heavy builds to clear waves quickly.
Increase your Magic Find, Resource Generation, and Speed Farming capabilities.
Look for events and whispers in dungeons that naturally include high mob density.

Pro Tip: Pair Strongroom farming with Glyph XP routes to maximize efficiency while hunting Arcana.
