Safecracking is a Thieving activity that was released on 30 April2018, which can only be accessed after completing all of the available capers in the Thieves' Guild. With level 62 Thieving, players can begin stealing from safes all over Gielinor. To get started, speak to the safe-cracking trainer in the Thieves' Guild to be given advice, a stethoscope, and a small loot bag. It is possible to crack a safe without this, but that results in significantly slower cracking and makes the player leave the spoils behind. The skill requirement for higher level safes can be boosted.
Players can open safes by turning a dial and attempting to open the safe upon observing a visual and audio cue. Experience is gained while trying to open a safe, with more experience rewarded for successfully opening it. After cracking a safe, the player can fill up their loot bag which can be fenced at the Thieves' Guild with Robin for coins and points to spend in Dodgy Derek's Dirty Deals. Almost all safes around Gielinor reset after 5 minutes of in-game time (world-switching doesn't work) with the only exceptions being the Zemouregal's Fortress safes which take 10 minutes to reset.
To open safes faster, players should keep an eye on the safe they are opening and wait for it to briefly flash blue. Clicking on the safe again when this occurs will immediately unlock one of the remaining locks on the safe.
In addition to filling up a bag of loot to exchange for coins and pilfer points in the Thieves' Guild, players will also receive thieving experience when fencing in their loot bags; there is also a chance of finding several special items while safecracking. Assuming the player completely fills their loot bag, they can expect the following Thieving experience:
