GPO- Dark Blade

The Dark Blade is a Mythical Sword that has a 0.5% chance to drop from the Hawk Eye Boss located on Umi Island.

The Dark Blade's attacks bypass Logia immunity without requiring Busoshoku Haki, even if the player's Haki is empty. This trait is shared with Ace and Kikoku.

This weapon is one of the few mythical weapons in the game to have all its skills available through swords mastery and is unique in being the first weapon to have a skill be modifiable.

The level requirement to trade it is 425+.
