An assassin's dagger, misshapen and stained in cerulean. Critical hits restore FP. This charm is modelled after the darkly gleaming blades used in the Night of Black Knives. Those which gave the demigods their first taste of death.

Dropped by the Black Knife Assassin boss found in Black Knife CatacombsGrace in the northeast of the Liurnia of the LakesRegion region. This boss is a secret second boss within the Black Knife CatacombsGrace 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. Sell Value: 1500. Small weapons like daggers that normally perform a single stab, switch to a double hit animation on large enemies. This will activate the effect of the talisman twice. Weapons that trigger this and similar talismans more than once: all Colossal Weapons, all Daggers, and all Great Katanas. Colossals and GK trigger on all backstabs, but will only trigger front stabs on smaller or downed enemies. Daggers only work on large enemy/boss ripostes (front stabs). The Dagger Talisman does not increase FP gained.
