The Granite crab has multiple uses: * Combat: it has a combat level of 19. In addition, its scroll Stony Shell provides a +4 boost to a player's Defence when activated. * Fishing: Grants an invisible +1 Fishing level boost. This boost cannot be used to catch fish that are 1 level above the player's original fishing level. * Forager: While the player is fishing, this familiar can forage for cod, pike, seaweed, and oysters. It can hold up to 30 of its foraged items in its own inventory. 5.5 Fishing xp is granted for each fish (cod or pike) produced by the crab. File:Stony Shell.gif
