Charos' clue carrier is a reward from the Desperate Times quest. It is a pocket slot item that can be used to store and withdraw sealed clue scrolls and reward caskets.
Any clue scrolls picked up as a drop or received while skilling, as well as any reward caskets obtained when completing a treasure trail, will automatically be stored in the clue carrier if it is worn or in the inventory. There is no imposed limit of how many of each item the clue carrier can hold outside of the standard 32-bit integer data type restriction for an item slot, meaning that the clue carrier is capable of holding up to 2,147,483,647 of each level of clue scroll and each corresponding casket. However, this does not circumvent the soft cap of clue scrolls.
The clue carrier cannot store clue scrolls that have already been started, nor can it store puzzle caskets. If the clue carrier is destroyed by the player or lost upon death, it will retain the items it contained when it is reclaimed.
