Diablo 4 Season 9 Arcana Spells guide: Drop rate, how to farm, and more

Arcana is one of the new items introduced in Diablo 4 Season 9: Sins of the Horadrim, which ties directly into the new Horadric Spellcrafting system. The Arcana, which allow you to augment and customize your Horadric Spell, are classified into three rarity levels: Legendary (can completely alter the functions of the spell), Rare (boosts the spell by adding better passive stats), and Magic (adds simple enhancements to your spell).

In this guide, we will shed more light on Arcana and how to get them in season 9 of Diablo 4.

How to farm Arcana in Diablo 4 Season 9

Arcana drops ran into a massive hitch in Diablo 4 at the beginning of Season 9 due to some bugs. While Horadric Phials’ drop rate got fixed with the July 2, 2025, Hotfix 2.3.0, nothing has been done to increase the drop rate of Arcana in the Horadric Strongrooms. However, Blizzard has promised they will fix these issues. So, how do you acquire Arcana?

You can game the system by resetting dungeons again and again by logging in and out. While adopting this strategy, there is a chance that you might get banned by Blizzard — something we have seen in recent weeks.

Alternatively, you can just run Horadric Dungeons as intended and hope that the drop rate gets fixed soon.

Use the Horadric Strongroom affix to guarantee Strongroom spawn within Nightmare Dungeons. Hunt through waves of monsters, and once you are done, you might have a chance to acquire Arcana. The best way to go through the Strongrooms is by using an AoE-heavy build.
