Contracts are needed to run Heists. In order to execute a Heist, you need to know the location of a valuable Artifact and what defences safeguard it. Contracts containing these clues can be found throughout Wraeclast alongside coins with the mysterious emblem of the Rogue Harbour.
Tips: since it is difficult to escape from a Heist, it is recommended to buy Contracts firstly, next upgrade your character, then play the contract. I always prepare a Heist when my character level is at least five levels higher than the contract's area level.
