Dagannoth Rex

Dagannoth Rex is a high level melee based boss monster located in Waterbirth Dungeon. Daggannoth Rex is by far the most popular boss out of the three Dagannoth Kings because of its unique drop, the berserker ring. In general, the Dagannoth Kings are scarcely populated because although all of the bosses have unique ring drops, they all have imbued counterparts that offer better bonuses. New players may find Dagannoth Rex (and the other Dagannoth Kings) very profitable, as some PKers do opt to use the rings they drop because they are inexpensive and almost as good as their imbued versions.

Strategy
Dagannoth Rex is quite weak to Magic based attacks. Although it can be fought with any attack style, in order to kill Dagannoth Rex with ease and precision, magic should be used. Dagannoth Rex can easily be safespotted and attacked from a distance but be sure to attack it southeast to its spawn, far away from Dagannoth Prime.
