About Rock-shell chunk
"A spherical chunk of rock-shell."
Rock-shell chunk is a Fremennik crafting component dropped by Giant Rock Crabs in the Waterbirth Island Dungeon and by King Sand Crabs in the Catacombs of Kourend. Players bring chunks to Skulgrimen along with a dagannoth hide and 5,000 coins to receive a rock-shell helm. It is also accepted by Askeladden as a Fremennik favour token.

Trading Tips
Stock up before Fremennik themed leagues or quest reworks.
Watch slayer task popularity for crab assignments.
Sell helms directly if margin beats the chunk markup.
