Abyssal demon

The Abyssal demon is a monster located on the third floor of the Slayer Tower and on Lunar Isle. They are known mainly for the rare drop: the Abyssal whip, as well as a common Slayer task from Vannaka. In order to kill them you need a Slayer level of 85. They are popular for clan slayer as people are intrested in the Abyssal whip drop and they also offer good exp.

PvM attraction
Abyssal demons are an attraction to PvMers as they can do their slayer tasks and have the chance of getting the prized Abyssal whip at the same time. The Abyssal Demon does not hit very hard, even if the player isn't using protection prayers. The abyssal demons are often empty due to players going to different locations for PvM e.g. the Tormented Demons.
