Flails are a type of Weapon in Elden Ring. Flails have long reach and can inflict single powerful strikes against hostile characters, but they are rather slow. Flails can be modified by a number of Ashes of War to change their Skills or Damage Type, so play around with them and see what you like as you acquire more. The default Art of War on most flails, Spinning Chain, is not available as a separate Ash of War as of Patch 1.03. This means you cannot change the damage affinity of these flails without overwriting Spinning Chain.
