Grotesque Guardians

The Grotesque Guardians are a pair of gargoyles found on the Slayer Tower's rooftop. In order to access the roof, players must obtain a brittle key from gargoyles while assigned them for a slayer task. The pair consists of the Guardian of Dusk and the Guardian of Dawn.

To initiate the fight, players must ring the Cloister Bell in the north side of the roof. This will trigger a cutscene in which the Guardians will awaken, and the fight will begin.

Similar to other slayer bosses such as Cerberus and the Abyssal Sire, the Grotesque Guardians can only be killed while the player is assigned gargoyles as a slayer task.
