Dark beasts are monsters that require 90 Slayer to kill, and are found in the Mourner Tunnels as well as in Iorwerth Dungeon in Prifddinas. Along with their superior variant, they are the only monster in the game to drop the dark bow and the death talisman.

Dark beasts attack with both Melee and Magic; however, they will only use Magic as their first attack if they are attacked by the player first, or if they cannot attack the player with Melee. Dark beasts do not follow tolerance rules, and are always aggressive to the player regardless of how long they have stayed in their presence. Their highly accurate melee attacks means that using Protect from Melee is recommended when killing dark beasts.

A combat level of 90 is required to have them assigned to the player as a Slayer task, unless the player has spoken to a Slayer Master about the difficulty of assignments; as well as 90 Slayer. The player also needs to have started Mourning's End Part II however no progression is required; if a player does not want them to be assigned do not continue the dialogue after completing Mourning's End Part I.

By default, Slayer Masters will only assign 10-20 Dark beasts for the Slayer task. However, the player can spend 100 Slayer reward points on Need more darkness to extend the amount assigned to 110-135.

Players who have a Slayer ring and completed Mourning's End Part II can rub the ring to immediately teleport to the dark beasts in the Mourner Tunnels. Another fast method to reach these dark beasts is the Death Altar through the Abyss. If the player cannot use these methods, then they will need to enter through the Mourner Headquarters.
