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. For levels 81 or higher, the odds are between 1/99 and 1/50, scaling linearly and capping at level 350, as reflected in the equation below.

If it concerns a Slayer monster (meaning it requires a certain Slayer level to kill), the drop chance is increased by 20%. In addition, any monster killed within the Wilderness Slayer Cave has a further 15% increased chance to drop a key. Keys are dropped on death. Superior slayer monsters that spawn as part of Krystilia's tasks will always drop a key on death.

The probability $P$ of obtaining a key when killing a monster with combat level $L$ is given by: $P={\begin{cases}{\frac {1}{\left\lfloor {\frac {3}{10}}\times (80-L)^{2}\right\rfloor +100}}&{\text{if }}L\in (0,80]\\{\frac {1}{\left\lfloor -{\frac {5}{27}}\times L\right\rfloor +115}}&{\text{if }}L\in (80,350]\\{\frac {1}{50}}&L\in (350,\infty )\end{cases}}$

Larran's key is always dropped on player death, even if there are fewer than 3 items kept on death. If killed by another player, the key is lost to the killer. If killed in PvM, the key always goes to your gravestone.
