Whopper-baiting scrimshaw

The whopper-baiting scrimshaw is an item that can be made with the Fletching skill at level 85 once all four scroll fragments of whopper-baiting have been retrieved from the Player-owned port, using 10 ancient bones. It requires 70 Fishing to be worn.

When equipped, it offers a 15% chance at increased experience while Fishing by hooking a larger-than-normal fish (which is not caught). Fish that get away do not count towards a Daily Challenge.

This is the Fishing equivalent of the rock-crushing and log-splitting scrimshaws.
