Dark beasts are monsters that require level 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.

In addition to level 90 Slayer, 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. The player also needs to have started Mourning's End Part II, however no progression is required; players who do not wish to be assigned them should 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.

Drops

Drop rates estimated based on 47,056 samples from the Drop Rate Project, unless otherwise cited.

The average dark beast kill in Iorwerth Dungeon is worth 1,984.00 due to the additional chance of receiving a crystal shard as a tertiary drop. This value for crystal shards assumes that they are made into divine super combat potions.

Trivia

• Upon their release, dark beasts used to look like a dark-brown version of the Temple guardian with a black horn.
