Larran's key is a key obtained from killing monsters while on a Slayer task given by Krystilia. It is used to open Larran's small and big chests.

The exact odds of receiving a key scales with the monster's Combat level. For levels 1-80, the probability follows a curve between 1/1972 at level 1 to 1/100 at level 80.[1] For levels 81 or higher, the odds are between 1/99 and 1/50, scaling linearly and capping at level 350,[2] as reflected in the equation below. In addition, if players are assigned to kill slayer monsters, the drop chance is increased by 25%,[3] and any monsters killed within the Wilderness Slayer Cave have a further 15% increased chance to drop a key.[4]

The probability ${\displaystyle P}$ of obtaining a key when killing a monster with combat level ${\displaystyle L}$ is given by: ${\displaystyle P={\begin{cases}{\frac {1}{\left\lfloor {\frac {3}{10}}\times (80-L)^{2}\right\rfloor +100}}&{\text{if }}L\in (0,80]\\{\frac {1}{\left\lfloor -{\frac {5}{27}}\times L\right\rfloor +115}}&{\text{if }}L\in (80,350]\end{cases}}}$

While untradeable, the killer will be able to receive the key upon killing their opponent. If the killer is an Ironman, the key will be automatically destroyed.
