Black Twin Daggers

Darker than the deepest seas, it's easy to use and incites fear into its prey.

There is a story that even after its wielder died, his arms went on moving and cut down anything that came near. Because of this, the workshop strictly orders owners: "These dual blades are steeped in Fatalis's rage, so harbor no evil in your heart." It is also said they stir up an urge to cut something, whatever it may be.
