Dagannoth Rex


Dagannoth Rex is one of three Dagannoth Kings which reside in the Waterbirth Island dungeon. His primary attack style is melee, however, the other two Dagannoth Kings – Prime and Supreme – use Ranged and Magic respectively. For this reason, if you’re not careful within the dungeon, you may be under threat from all three combat styles at once.

There are two common tactics used at the Dagannoth Kings. Rex is the only Dagannoth King which you can comfortably solo without having to deal with the other Dagannoth Kings. If you are looking for info on the tribrid method, you should check out our guides on Dagganoth Prime and Dagannoth Supreme.

There are a few reasons why players regularly kill the Dagannoth Kings.

  • Each Dagannoth King has a unique best in slot ring drop – a coveted drop for ironmen.
  • The Freminick Elite diary unlocks the ability to acquire all Dagannoth King bones as noted, which increases the profitability of the DKs substantially.
  • Slayer tasks of Dagannoths are quite common and high-level players will often do the task at DKs for the high profits.
  • Dagannoth Kings are a fun, profitable group activity for friends and clans alike.

Waterbirth Dungeon Notes – In order to get through the first section of the Waterbirth Dungeon, there is a stone door which requires two players to stand on two separate triggers. If you are alone, you can use a ‘pet rock’ instead of a second player – which can be acquired from The Fremennik Trials quest.

The next section of the Waterbirth Dungeon requires you to use the special attack of a Rune thrownaxe.

The rest of the Waterbirth Island dungeon and the route to the Dagannoth Kings can be treacherous if you don’t plan ahead. You can view a full map of the dungeon here.

Notable Drops

DKs - Mage (Solo Rex) Guide

The solo mage method at Dagannoth Rex requires you to stay in one specific corner of the dungeon in order to avoid Dagannoth Prime and Dagannoth Supreme. When Dagannoth Rex spawns, use your trident on long-ranged mode to lure Rex to your corner of the dungeon. When he gets closer, there is a specific corner of the dungeon in which you can trap Rex (view here) so that he cannot attack you.

Once Rex is trapped, you can easily just kill him with magic without taking any damage.

When Rex is dead, you can either use Guthans or Blood spells to heal up on the minions around you.
