Abyssal demon - OSRS Wiki

Abyssal demons are one of the strongest types of demons, requiring level 85 Slayer to be damaged. Alongside their boss variant, they are the only creatures in the game to drop the abyssal whip and abyssal dagger. They have relatively high accuracy but their max hit of 8 is low for their combat level.
