Rock-shell shardmembers
“A curved piece of rock-shell.”
About this item
Rock-shell shards are dropped by Giant Rock Crabs and King Sand Crabs. These are used to make rock-shell plates by giving Skulgrimen 3 dagannoth hides, 10,000, and 1 rock-shell shard. Creating the plate requires completion of The Fremennik Trials. It can also be exchanged with Askeladden on Waterbirth Island for cooked tuna before The Fremennik Trials or cooked lobster after the quest.

Its high alch value of 36 does not cover the 155 nature rune it would burn, so alching is a loss before the item itself is counted.

Measured with medians rather than averages, because one spike — an update, a streamer, a brief squeeze — drags an average around for weeks afterwards and makes everything since look ordinary.
