Dagannoth Rex is the Melee-based Dagannoth King found in the depths of the Waterbirth Island Dungeon, along with fellow Dagannoth Kings, Dagannoth Supreme and Dagannoth Prime. Rex is the only monster to drop the Berserker and Warrior rings, which can become best-in-slot rings for Strength and Slash after being imbued at the Nightmare Zone. He, along with the other Dagannoth Kings, can also drop the rare dragon axe.

Strategy[edit | edit source]

Main article: Dagannoth Kings/Strategies

Luring Rex to a safespot.

Dagannoth Rex has an extremely low Magic Defence, so it is recommended to use Magic against him. Popular choices include Slayer Dart, Iban Blast, and powered staves.

Due to his large size and the fact he uses melee attacks only, it is recommended to get him stuck on one of the ridges of the lair and safespot him (note that Spinolyps will still be constantly attacking while you're safespotting). Many players use high-level armour such as Barrows armour, which give high Defence bonuses while still being able to hit Rex constantly with spells due to his very low Magic Defence, even if their magic attack bonus is below zero. Players who use Guthan's are advised heal themselves on the Spinolyps while waiting on respawns to help preserve food and potions.

Dangers[edit | edit source]

If players venture too far out west to lure Dagannoth Rex, they risk attracting attention from both Dagannoth Prime and Dagannoth Supreme, namely Prime since he wanders closer to the east and north-east. This can be avoided by staying in the southeastern part of the arena, as Prime will rarely (if ever) go there, and attack Rex only when he's nearest to the east.

Drops[edit | edit source]

Drop rates estimated based on 217,761 kills from the Drop Rate Project, unless otherwise cited.

The average Dagannoth Rex kill is worth 31,177.13.

The average Dagannoth Rex kill while on a Konar task is worth 32,831.9.
