In RuneScape Classic, the Sleeping bag was used to decrease fatigue without having to journey to a bed. The player would receive one by talking to the Fatigue expert on Tutorial Island. It would take up one inventory space, and was a very common item for players to carry everywhere. When used, a screen would appear asking the player to type in a random word to wake up. This word was displayed in distorted letters below the input line. Fatigue was an effort to create an obstacle for autoers and affected mining, fishing, and similar activities. This item was not transferred over to the new game because random events replaced fatigue in RS2, although the sleeping bag existed briefly in the beta. Therefore, it is only seen in Classic.
