The brimstone key can be obtained from killing monsters while on a Slayer task given by Konar quo Maten. It is used to open the brimstone chest. The average value of a drop from the brimstone chest is 85,655.15 (HA: 25,803.98). Upon death in the Wilderness, a brimstone key converts to two coins for the killer.

The probability of receiving a key as a drop increases with the slain monster's Combat level. For monsters with combat level 100 or higher, the probability is between and , capping at level 350. Specifically, the probability for a monster with combat level is[1]

For monsters with combat level smaller than level 100, the probability follows the curve[2]

Additionally, if the monster has a Slayer level requirement, there is a 20% boost in the drop probability.[3]

A brimstone key is always dropped by a superior slayer monster assigned by Konar.

8 May 2024
(Update)

Superior slayer monsters are now guaranteed to drop brimstone keys when on a task from Konar.

28 May 2020
(Update)

A bug causing the Brimstone key drop rate to be lower than intended for monsters with a combat level of 100 or higher was fixed.[4]

Trivia

  • The symbol on the key is a taijitu which represents the concept of Yin and yang ("阴阳"/"陰陽"), which, in Chinese philosophy, are the two "primal" elements which create, shape, and influence everything in existence and have to be kept in balance. This references the philosophy of the Kahlith and their masters, the Tasakaal, which is to maintain the balance between life and death.
