Crab Claw

Crab Claw is a quest item that is obtained by defeating Crabs. It has no use as a normal crafting material or combat item; its role is to satisfy quest requirements tied to crab-related objectives.

Because it is a quest item, Crab Claw should be kept until the relevant quest is completed. After that, it no longer serves a direct gameplay purpose. Since it drops from Crabs, the most straightforward way to collect it is to hunt crabs in areas where they spawn and continue until the required drop appears.
