Dagannoth are sea monsters. Many are found near areas inhabited by the Fremennik, who call them daggermouths and hunt them for their skin, which is used to make armour. There are many types of Dagannoth, the most powerful being the three Dagannoth Kings. Dagannoth are assigned by Chaeldar, Vannaka, Nieve and Duradel as Slayer tasks.
Little is known about the origins of the dagannoth species. Dagannoth are first documented in Third Age where they started attacking the Fremennik, causing great losses to them. The Fremennik call the Dagannoth "dagger-mouths", most likely due to their sharp teeth.
There are several types of Dagannoth, which vary by level, location and occasionally name. For information on a specific type of dagannoth, see its article.
