A stealthy blade, distorted and marked with cerulean stains.

Critical hits replenish FP.

This talisman is fashioned after the sinisterly gleaming blades wielded during the Night of Black Knives, the ones that granted the demigods their initial encounter with Death.

How to get it: Dropped by the Black Knife Assassin boss found in Black Knife Catacombs in the northeast of the Liurnia of the Lakes region.

This boss is a secret second boss within the Black Knife Catacombs that is found behind an illusory wall.

From the room with the falling blades, stand on top of one after it drops to be lifted up, giving you access to a hallway heading south.

Continue heading south into the room and turn right; the illusory wall is the west wall at the end of the next room.
