The Ash of War bestows Magic affinity upon an armament and introduces the skill "Glintblade Phalanx."

This skill, used by enchanted knights who served the Carian royal family, involves forming an arch of magic glintblades overhead that automatically attack foes.

Follow up with a strong attack to chain this skill into a lunging thrust.

Usable on swords as well as polearms capable of thrusting, with colossal weapons excepted.

To obtain these Ashes of War, proceed to the terrace of the round table hall and converse with Roger after defeating the BOSS "Grip" Greco in Stonewell City.

After informing Roger Greco of his defeat, you will receive Roger's Rapier, and the Battle Ashes can be obtained from this weapon.
