Forked daggers, each blade honed to perfection. A single stab will lead to a world of pain. Also known as Claw glowing with evil. It's a main weapon for Kisala. Tips about the blueprint can be obtained from Dorban and Duella. Dorban is at Rosa inside Shilawa's shop. Duella is at Zerard inside Alice's shop. Once manufactured this item will be on sale at Alice's shop. The earliest time you can develop these daggers is by chapter 8, but if you don't have a Chameleon Particulate from an Assault Walker drop or from a Cancer King's Ruins chest, you'll have to wait until chapter 10 to buy it from Bivine.
