The Crystal claw is the strongest claw available. Just like the Crystal bow it degrades as you use it. The Crystal claw requires 70 Attack to wield and can be obtained as a drop from the Crystal dragon. It also has an off-hand variant. Like all other Crystalline items, the claw has 10 Charges. For ever 100 hits, it will degrade by 1 so it would become Crystal Claws 9/10, 8/10 and so on. Once it has been completely used up, it will turn into a Crystal weapon seed. You can recharge it by talking to Ilfeen in Isafdar or you can talk to the Weapons Merchant in Cardiff on the island of Carydwyn.
