OSRS Black Demon Slayer Task Guide: Cannon Strategy

Strategy for Black Demons

Black Demons are weak to all attack styles and only attack using melee with a max hit of 16. In the Catacombs of Kourend, simply pray protect from melee, turn on auto-retaliate, and attack them. Walk a couple times away from their aggression zone when they get tolerant of you and return to reset their aggression.  

Cannon strategy

The best spot for setting up a cannon to kill Black Demons is in the Tarverley Dungeon since their spawns are clustered there unlike in the Chasm of fire where they are more spaced out. Pray Protect from melee, turn on Auto-retaliate  and set your cannon in the spot shown below.
