Protean plank

Protean planks can be won on Treasure Hunter or randomly given by a Shiny Four-Leaf Clover Necklace. They are stackable planks that are usable in place of any other type of plank.

They cannot be used in clockwork toys, to upgrade the pig machine under Falador farm, to construct a frame for Grapevine seeds, nor to repair the ladder to the Death Plateau Beacon in the All Fired Up Mini Game.

When using a portable sawmill to create planks, it is possible to receive protean planks instead.

Trivia

 * Protean planks used to be obtainable from the Squeal of Fortune. This was replaced by Treasure Hunter.
 * The name comes from the Greek sea god Proteus who could change his form.
 * Previously, if making flatpacks, production did not stop when the player's inventory was filled. Excess flatpacks were dropped. This was changed in an update on 26 November 2013.
