Dagannoth Rex is the melee Dagannoth King found on Waterbirth Island. He is completely immune to ranged and melee. Dagannoth Rex is the only dropper of the berserker and warrior rings. He, along with the other Dagannoth Kings, can drop the dragon hatchet.

Obtaining all unique drops from the Kings will unlock the [Name] Bukalla's Heir title.

Strategies

Dagannoth Rex is extremely weak to magic attacks, specifically fire spells. Whoever is killing him may want to use the southeastern side, as he can be easily fought there due to his large size.

Many players trap him as his melee attacks will be unable to attack the player. There are many safespots around the arena, but it's best to use a few if you only want to kill him. The best ones would be on the eastern side, as no kings will interfere unless they have been alerted to your presence (e.g. a player moves to your spot with Supreme on him, which makes you also get attacked with ranged).

Because Dagannoth Rex can easily be safe spotted, he is the easiest Dagannoth King to fight.
