Protean cog detail

Protean items are a group of items available from Treasure Hunter (and related promotions) used to train skills without producing an output (with some exceptions).

All protean items are stackable, allowing easy training of the associated skills. They also work in conjunction with portable skilling stations, bonus experience, brawling gloves, and Double XP Weekends, making them popular to save for use during bonus experience events.

All protean items can be turned into any other protean item using a right-click 'Convert' option, at a 3:2 ratio.

Protean items cannot give skilling pets.

Protean planks are the most different to any other protean item, as they do produce items. The planks can function as any other plank when constructing items, so the ideal use is to make items that require solely mahogany planks.


Protean bars are smithed on any anvil, via a unique Smithing action based on your level in the skill: level 1-15 performs 'Protean bronze smithing' for 75 experience per bar, up to level 85+ performing 'Protean rune smithing' for 450 experience per bar. Each Make-X action uses up to 60 protean bars, at 4.8 seconds per bar.


Protean traps are laid like normal bird snares, box traps, or marasamaw plants at a relevant Hunter area. The trap has an increased chance to catch creatures, lasts 50% longer before decaying, and when it does catch a creature it grants 25% more experience. If it fails to catch the creature, the trap is still consumed, but it still grants 50% of the normal catch experience. No drops are obtained from the traps.

Protean traps can be automatically deployed using a right-click option. This lays up to 60 traps (after which auto-deploy needs to be clicked again) and automatically checks them.


Protean hides can be crafted anywhere (thread not required) give experience based on your level (unlike bars, it increases with every level, not just at specific intervals). Each Make-X action uses up to 60 protean hides, at 3 seconds per hide.


Protean logs can be fletched, burned, or both, for experience.

  • They can be burned singularly (creating a fire), added to a bonfire or portable brazier for Firemaking experience alone - after 60 logs added a bonfire/brazier, you pause and must click again to continue.
  • They can be fletched anywhere for Fletching experience alone (up to 60 actions per Make-X).
  • They can be 'fletched and burned' anywhere for both Fletching and Firemaking experience - half as much in each as would've been obtained from doing that skill alone (up to 60 actions per Make-X).

Alternatively they can be converted into protean planks 1:1 by a sawmill operator for 5 coins each.


Protean memories can be released anywhere for Divination experience. The experience gained is based on the highest 'tier' of divine energy that you can harvest; boons increase this experience. Up to 60 can be released per Make-X action, at 4.8 seconds each.


Protean cogs can be converted anywhere to train Invention.
