**Dagannoth Rex**
Dagannoth Rex is the Melee-based [[guides:dagannoth_kings|Dagannoth King]] found in the depths of the Waterbirth Island Dungeon, along with fellow [[guides:dagannoth_kings|Dagannoth Kings]], [[npcs:dagannoth_supreme|Dagannoth Supreme]] and [[npcs:dagannoth_prime|Dagannoth Prime]].
**Fight overview**
Dagannoth Rex attacks with a Melee attack. Around the perimeter of the lair, Spinolyps attack the player with a weak range-based magic attack. Using the Protect from Melee prayer and staying out of the range of the other two kings is recommended to minimize damage taken.
**Fight Technique**
While Rex is technically weak to Magic, Melee is the recommended attack style here.
**Location**
The Dagannoth Lair can be reached by using the [[guides:dagannoth_kings|Dagannoth Kings]] teleport in the Monsters tab of the Spellbook.
**Drops**
Dagannoth Rex has several notable drops. The full Drop tables can be found on the official [[stats:drops|Wiki Drops Page]]. This page will automatically update if any changes are made.
