Protean planks can be won on Treasure Hunter. They are stackable planks that are usable in place of any other type of plank in the Construction skill.

If protean planks and other plank types (including any planks in a plank box) are in the inventory, the other plank types are used before the protean planks.

They cannot be used:

• in clockwork toys or
• banners,
• to upgrade the pig machine under Falador farm,
• to build rope racks,
• nor to repair the ladder to the Death Plateau beacon in the All Fired Up minigame.

They can be used to construct frames for grapevine seeds.

Protean logs can be turned into protean planks at any sawmill at the cost of 5 coins for each plank.

The most cost-effective use of protean planks is to treat them as stackable mahogany planks, and make items such as mahogany tables, flotsam prawnbrokers or mahogany armchair flatpacks.

Protean planks, as with all protean items, can be converted at a 3:2 ratio into other protean items.

Trivia

• 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 2014.
• Prior to 3 May 2016, protean planks could be produced on portable sawmills.
