Wall safes are found in the Rogues' Den, which can be cracked with 50 Thieving. Successfully cracking a safe in the lobby grants the player 70 Thieving experience and loot in the form of coins or uncut gems. If the player fails to crack a safe, a trap will spring and deal damage to them. The chance of getting loot is increased if the player has 50 Agility and has a stethoscope (available from the NPC Martin Thwait nearby) in their inventory. There are 4 wall safes found in the lobby and 8 found in the Rogues' Den minigame.

## Minigame

The safes found inside the minigame have three possible outcomes it can offer: failure, a rogue kit, or a rogue's equipment crate. The chance for one of the three chances are as follows:[1]

1. Roll a number 0-199.
2. If the roll is greater than the player's current visible Thieving level, there is a 50% chance to fail and be ejected and a 50% chance to drain Thieving by 1 and roll again.
3. If the roll is less than the player's current visible Thieving level, roll for the kit and crate.
4. There is an option of being able to pick either a kit or crate on a successful crack.

### Rewards

Item Quantity Rarity Price High Alch
Rogue kit13/8[r 1]Not sold30
Rogue's equipment crate15/8[r 1]Not sold0
1. Rogue kit and rogue's equipment crate are only rolled for if the player successfully cracks the safe.

The probability of receiving a Rogue's equipment crate from a Wall safe crack attempt for a given Thieving level is:

${\displaystyle {\text{CrateChance}}={\frac {5}{8}}*\sum _{i=0}^{\text{Thieving}}\left[{\frac {{\text{Thieving}}-i}{199}}*\prod _{j=0}^{i}\left[0.5*\left(1-{\frac {{\text{Thieving}}-j}{199}}\right)\right]\right]}$

The tables below show the corresponding chance of receiving a crate and the expected number of safe crack attempts to receive the full Rogue Outfit set.

The percentage above includes failures to crack the safe as well as the chance of getting a rogue kit instead.

The calculations assume the player is taking no risks with the traps.

## Lobby

The chance of successfully cracking a safe without a stethoscope is ~33% at level 50 Thieving and ~63% at level 99 Thieving. The chance of cracking a safe with a stethoscope is ~41% at level 50 Thieving and ~75% at level 99 Thieving. The rate of success increases linearly with each level.[2] It should be noted these success rates represent the chance of successfully cracking the safe on the first attempt (roughly 2 seconds after clicking the safe). Success rates per click will be higher as the player will automatically make another attempt to crack the safe every 2 seconds (4 ticks), until they either crack the safe or trigger a trap. Per click, cracking the safe or triggering a trap can take anywhere from 2 seconds to upwards of 18 seconds depending on luck, with a success rate estimated between 49% at level 50 and 77% at level 99 (58% to 86% with a stethoscope).

When failing to crack the safe, the player will trigger a trap, hitting them between 2 and 6 damage regardless of Thieving or Agility level.[2] A floor trap spawns under the player with a "Search" option, however this option will lower the player's Thieving level by 1 and does not appear to significantly affect the player's chance of successfully cracking the safe. Considering the floor traps in the maze operate the same way, it's likely this option is unintentionally left-over functionality (although this hasn't been confirmed by Jagex).

It is recommended to have some cheap food, e.g. jug of wine or cake (which can be stolen from the stalls in East Ardougne) to heal with. A bank is located nearby. There is also an everlasting fire nearby, so the player can bring raw food and cook it or buy cooked food from other players who are training Cooking at this location. Players may also want to consider wearing the regen bracelet to lengthen their stay at the safes. Players can also use Rapid Heal if they can get their equipment prayer bonus up to or over 50, lengthening their stay.

As uncut gems are rewarded so frequently, its a good idea to bring along a gem bag to cut down on bank trips.

The wall safe resets in only a few seconds. This activity can grant up to 1,500 experience per minute, or 90k experience per hour, assuming no failures; realistically it is usually significantly less (around 20k/h).
