Abyssal demon

Abyssal Demon's are vicious Demon's that require a Slayer level of 85 to kill.

They are commonly saught after because they drop the prized Abbyssal Whip which is currently the best weapon in the game.

RuneShark (Sc0ooby Doo) was the first person to achieve 85 slayer on the 10th of March 2013 and received his first whip drop on the same night.
