The Ash of War grants Flame Art affinity to an armament and introduces the skill "Black Flame Tornado."

This skill involves spinning the armament overhead and then plunging it into the ground to summon a raging vortex of black flames.

Holding the command creates an initial flame tornado while spinning the armament.

Usable on polearms and twinblades.

To obtain these Ashes of War, head to the altar of the Dragon Church in Sky City.

Defeat the BOSS god skin duo to obtain the Battle Ashes.
