Rock-crushing scrimshaw detail

The rock-crushing scrimshaw is an item that can be made with the Fletching skill at level 85 once all 4 scroll pieces of Rock Crushing have been obtained in the Player-owned port minigame.

The scrimshaw can be activated on and off for a total of 3 hours after which it degrades to dust.

Players require level 70 Mining to wear this scrimshaw. When equipped, it offers a 15% chance to crush the ore (losing it in the process) in exchange for increased experience while Mining.

The crushed ore appears to give 38% bonus experience, which means 15% chance to give 38% bonus experience. This works out at about 5.7% bonus experience.

This effect does work when mining rocks in the Living Rock Cavern. However, the effect does not work with Seren stones or alaea crablets. Crystallise spell does not work with Rock-crushing scrimshaw.
