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 RuneScape. To get started, speak to the safe-cracking trainer in the Thieves' Guild to be given advice and a stethoscope. It is possible to crack a safe without this, but it is significantly slower.
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 a bag of loot which can then be traded in at the Thieves' Guild for points to spend in Dodgy Derek's Dirty Deals. It takes around 5 minutes for most safes to reset.
Rewards from safecracking include the ability to purchase and put a master thief's stethoscope and lockpick on the tool belt and items that can aid with other Thieving training. It is possible to obtain Ralph from safecracking.
