The Ash of War, upon application to a weapon, imparts the Heavy attribute and introduces the ensuing technique:

"Ground Stamp (Upward Cut): Stabilize the armament, assuming a low defensive stance that nullifies recoil from the majority of enemy assaults. Subsequently, execute a powerful upward strike with a robust follow-up."

Applicable to swords, axes, and hammers (excluding small and medium-sized swords).

These war ashes are situated within the dilapidated residence of the Nimgfu warriors.

To obtain this Ash, one can procure it from Bernal by expending 1500 runes in a transaction.
