How to Use Ashes of War in Elden Ring

Quick Answer

Apply a compatible Ash of War to a standard weapon at a Site of Grace or through a smith, choose an available affinity, then use the skill input while that weapon's skill has priority.

Before You Start

• Confirm the weapon accepts interchangeable skills.
• Acquire the desired Ash of War.
• Apply it through the Ashes of War menu.
• Choose an affinity supported by owned whetblades.
• Equip the weapon so its skill takes priority.

FAQ

What should I check first?

Check the current objective, game version, platform or edition, and the prerequisite named in the Quick Answer. Those four checks resolve most cases where the expected option is missing.

Can this change after an update?

Yes. Live-service balance, interface routes, and some progression requirements can change. The source and verification date below define the boundary of this answer.

Does this guide include hidden odds or exact values?

Only when an authoritative source publishes them and they remain necessary to answer the query. It does not invent drop rates, damage values, prices, coordinates, or patch numbers.

Where should I go next?
