Blade of the Abyss is a very powerful Legendary Cursed Cutlass with a very punishing and unique Inferno Sweep Break Attack ability that surrounds all enemies facing you in a blazing green fire for 10 seconds. Blade of the Abyss is the only weapon able to use Inferno Sweep. This Weapon has an attack power of 93, making it one of the strongest cutlasses in the game. This is the only weapon besides the Heart of Padres del Fuego to have Blood Fire Rank 3, which makes the weapon even more lethal as it defeats Enemies. This Cutlass boosts the wielder's Sweep Skill as well. This blade leaves behind a blood red shadow, instead of the traditional black shadow of all Cursed Blades (except for The Emerald Curse which has a emerald green shadow following it). Even though the sword looks like a Broadsword, such as the famed Barracuda Blade, it is a Cutlass. You can tell them apart because of its unique blood red shadow that trails it, or because its combo moves are hack , slash , cleave , flourish , and thrust while the broadswords' combo moves are chop , roundhouse, spin cut, reverse spin cut, and jumping slash .
