The Ash of War confers Blood affinity upon an armament and imparts the skill "Blood Blade."

This skill involves wounding oneself to coat the armament with blood, then unleashing an airborne blood blade that causes hemorrhaging.

It can be fired in rapid succession.

Usable on small and medium swords.

To obtain these Ashes of War, head to the northeast side of the hill near the Golden Tree on the Yatan Plateau.

In the pond, there is a dung beetle floating in the air. It will automatically fall to the ground when approached, and you can acquire the Battle Ashes by defeating it.
