Superior rock-crushing scrimshaw


 * This item has an inferior version.

The Superior rock-crushing scrimshaw is an item that can be made within a players' port workshop at level 85 Fletching once all four scroll fragments of Rock Crushing have been retrieved from the Player-owned port minigame. This item will last 4 hours after which the player will need to make a new one.

When equipped, it offers a 20% chance to crush the ore (losing it in the process) in exchange for increased experience while Mining.

When using this scrimshaw along with juju mining potions, the rock-crushing effect has priority over the auto-banking effect, so that ore will be crushed rather than auto-banked when a stone sprite is active. However, when varrock armour or golden mining armour is worn, if two pieces of ore are obtained, only the first will be crushed. The second may be auto-banked if a stone sprite is active, or will appear in your inventory.
