Abyssal demon

Abyssal demons are located at the top of the Morytania Slayer Tower and in the depths of the dark Abyssal Area (which is not the Abyss). Only players with level 85 Slayer can fight these demons and obtain their drops.

Abyssal demons are the ultimate goal of many slayers, because of the rare-but-valuable Abyssal whips they can drop. The whip is regarded by many as one of the best weapons in RuneScape, so it is always in demand and sells well on the Grand Exchange. Slaying abyssal demons can therefore be very profitable.

Higher levelled players may find it easy to stay for long periods of time, using a Saradomin godsword, a healing familiar (e.g. bunyip), or a combination of the two. These methods require minimal food usage and the occasional lobster drop can sustain most players for hours while healing with the above methods.

If players bring an Abyssal demon head to the Taxidermist in Canifis, she will remark "It's still glowing" and the effect is preservable with magic, despite that neither the living nor stuffed versions of the Abyssal Demon glow.

The Abyssal demon was the only Slayer monster that did not receive a graphical update on or about the time the Smoking Kills quest was released in 2008.

Strengths and weaknesses
As the Abyssal demon is indeed a demon, it is affected by the powers of Silverlight and Darklight. Abyssal demons hit very low considering their level, with a maximum hit of only 8 damage. This makes them very good targets when using Guthan's or Dharok's sets, because of the low risk of dying.

Abyssal demons have the unusual ability of teleporting around the room. They look a lot like shifters, who also teleport during battle.
