Subcontract was removed from RuneScape after an update, but still exists in-game for those who had obtained it.

Subcontract is an item that can be used to skip tasks on the assassin's contract during the Faceless Assassins promotion on Treasure Hunter. It has a Retrieve List option that allows you to retrieve the Assassin's contract if it is destroyed or in the bank.

After prestiging the contract five times, the remaining subcontracts can be redeemed for experience equivalent to that from a medium prismatic lamp.

Trivia

• Although they cannot be banked, subcontracts can be taken into Daemonheim. Likewise, a hotfix on 24 January allows subcontracts to be taken into Heist. This allows players to complete the relevant contracts without having to destroy subcontracts. They cannot retrieve the Assassin's contract while in Daemonheim however.
