The de-lore-ing device is an item used to time travel in Back to the Freezer. It is made by combining the de-lore-ing device (incomplete), flax cap-ice-i-tor, and The Penguin Book of Gielinor. It receives additional tuning from the monkey wrench, cabbage, cowbells/bongos, and worthless old boots to be fully working and to progress in the quest. At any point in the tuning process, it can be 'de-activated' via a right-click option to return to the iceberg.
