Superior tree-shaking scrimshaw

The Superior tree-shaking scrimshaw is an item that can be made within a players' port workshop at level 90 Fletching from 10 ancient bones once all four scroll fragments of Tree Shaking have been retrieved from the Player-owned port minigame. The scrimshaw lasts for 4 hours of use, and can be activated and deactivated as desired, except for a minimum activation period of 10 seconds.

When equipped, it increases the chance of finding Bird's nests while Woodcutting and Crystal geodes while chopping Crystal trees by 400%. It also gives a chance to find Implings, ranging from an essence impling (very common) all the way to a Crystal impling, however crystal impling can only be caught using the scrimshaw in the Crwys clan area while the Voice of Seren is on it with the chances are best being from magic/elder trees).

Implings found using the scrimshaw last 5 minutes before despawning and are only visible to the wearer of the scrimshaw, although they are audible to other players. When an impling appears, the following message is shown in the chatbox:

NOTE: Before the 17 June 2013 update you could not catch disturbed implings bare-handed, but instead needed to be using butterfly net and implings jar to do so. It is unknown if this was a bug.
