Flamberge is a Greatsword that scale primary with Strength and Dexterity. It has bleed build up by default, also can be infused with Ashes of War and buffed with Magic or Consumables.

Combine with Flaming Strike Ash of War, You can unleash a burst of flame, then execute a powerful sweeping attack that ignites your weapon with fire for 40 seconds, and adds 90 flat Fire Damage in it.

What I like about this Ash of War is that you can flinch small enemies. Also, the burst of flame has a good area of effect, making it ideal for hitting multiple enemies in front of you
