Abyssal Demons

Abyssal demons are located at the top of the Morytania Slayer Tower, Stronghold Slayer Cave and the depths of the dark Abyssal Area. They are the only creatures in the game to drop the much coveted abyssal whip. A Slayer level of 85 is required to fight it. It is one of the few high-level slayer monsters that you can fight regardless of whether or not they are your currently assigned task, which make killing them a decent money-making method, provided you have the appropriate combat and slayer levels.

Being a demon, this creature is affected by the powers of Silverlight and Darklight.

Killing an abyssal demon grants 600 experience in the attack style that the player is training, as well as 199.5 Hitpoints experience.
