Dark Demonbane is a spell within the Arceuus spellbook that requires level 82 Magic and the completion of A Kingdom Divided to be cast. This spell has a base max hit of 30 but can only be cast on demonic creatures.

By default, demonbane spells have an accuracy bonus of 20% but can be doubled to 40% when the Mark of Darkness spell is active, which additionally gives a 25% damage bonus. If attacking with a purging staff, this is further doubled to an 80% accuracy and 50% damage bonus when under the effects of the Mark of Darkness. All of these bonuses are calculated after the player's own magic damage bonuses from their equipment.
