Slayer

Slayer is a -only skill that allows players to kill otherwise immune monsters, released on 26 January 2005. Players may go to a slayer master and get an assignment, and will gain Slayer experience for killing the assigned monsters. The experience gained per monster is usually equal to the monster's hitpoints. Slayer experience is granted in addition to regular combat experience. Slayer can be very profitable since many Slayer assignments drop rare and profitable items, such as abyssal whips dropped by abyssal demons that require level 85 or higher Slayer to kill.

Soul Wars and Penguin Hide and Seek are alternative ways to gain Slayer experience.

Note: many Slayer creatures drop grimy herbs, which gives players the option of training their Herblore skill while slaying.

Variations of monsters count towards the slayer assignment. For example, if a player has been assigned to kill Blue Dragons, they may instead slay Baby blue Dragon and still receive Slayer experience. Since the amount of experience received is based on the monster's hitpoints, there are advantages to slaying the assignment with the most hitpoints. See Slayer substances for a list of known substitutes.
