Dagannoths are sea monsters found in RuneScape, an MMORPG designed by Jagex. They are extremely similar to a Xenomorph. According to the Fremenniks, a tribe of barbarians, they are known as Dagger-mouths (probably for the reason that their teeth are similar to little daggers). There are many types of Dagannoths, with the most powerful being the 3 Dagannoth kings.

The Dagannoth mother

As part of the Horror from the Deep quest, a player will eventually have to go into the basement of a lighthouse, where he or she will have to face a Dagannoth, which is level 100. The Dagannoth only uses melee and is pretty easy to defeat. After the Dagannoth is defeated, its mother will come out. She can use melee and ranged, and frequently changes colours. When she is a particular colour, only certain types of attacks work effectively against her, otherwise the player's attacks will hardly do any damage. Below is a list of the colours she can change to and what type of attack works effectively against it.

White (Wind spells)

Blue (Water spells)

Orange (Melee attacks)

Brown (Earth spells)

Red (Fire spells)

Green (Ranged attacks)

The return of the Dagannoth Mother

During the Recipe for Disaster quest, players will face a Culinaromancer, a mage who specialises in food spells. During the final battle, he will summon five infamous quest bosses and cast a food spell on them, making them bigger, stronger, and tastier than ever. However, not even the gods will venture into this devilish meal, so prayers are disabled during these battles. The Dagannoth Mother is the final one players will face. During the battle, she is level 130 and known as the Gelatinnoth Mother. She is made out of jelly and throws rings of jelly at players for a ranged attack. Besides being a higher level and having slightly stronger attacks, she is defeated the same way as in Horror from the Deep.

Lighthouse Dagannoths

After players are done with the Horror from the Deep quest, regular Dagannoths will take over the lighthouse basement. They are level 74 and 92. They both use a ranged attack, and it has terrible aim. However, the level 92 Dagannoths also use melee, which is much more accurate. They will try to melee players whenever they get a chance to. These Dagannoths are in a multicombat area, so they are a good training place for players who have a cannon or are training their Slayer skill. The lighthouse Dagannoths also drop a large assortment of high level herb seeds, all above ranaar. They also drops Belladonna seeds, used in making super weapon poison(s).

Waterbirth Island Dagannoths

In the dungeon on Waterbirth Island, there are many unique types of Dagannoths and other sea monsters. First, there are level 90 Dagannoths. These use melee and can hit over 20 damage. There are also level 42 Dagannoth Spawn. They hatch from the eggs that are scattered all over the dungeon. Finally, there are level 88 Dagannoths that use ranged and hit over 20 as well as level 70 Dagannoth Fledgelings (which can only hit a max hit of 7). This is to be avoided by new players to the game.

Treasure room Dagannoth

RuneScape players can now build their own houses using the construction skill, a feature that many have been waiting for since 2002. As players get their level up, they can build more rooms. At level 75, they can build a treasure room for their dungeon. Inside the treasure room, there is a boss monster that must be defeated before the treasure can be claimed. Level 90 gives players the option to build a level 135 Dagannoth as the boss. This Dagannoth uses melee and ranged.

Dagannoth Kings

At the very bottom of the Waterbirth Island Dungeon, there are 3 legendary level 303 kings. They are known as Dagannoth Prime, Dagannoth Rex, and Dagannoth Supreme. Dagannoth Rex uses melee, Dagannoth Prime uses magic, and Dagannoth Supreme uses ranged. They can hit up to 30 to 50 maximum depending on which is fought, and they drop the much sought after Dragon Hatchet, Seercull (Bow), and Mud Staff. They can also drop Fremmenik rings (Seers, Warrior, Archer, and Berserker), which are similar to the Fremmenik helmets (they add stats to attack skills). They can also drop Dagannoth bones, which give more prayer experience when buried than dragon bones. Like the rest of the monsters in Waterbirth Dungeon, the best way to kill them is to fight based on the combat triangle. So use melee on the Dagganoth Supreme, ranged on the Dagganoth Prime, and magic on the Dagganoth Rex. Bringing a group is very important. Using a cannon on these three monsters is not recommended as it will draw attention from the other monsters in the area. Other monsters similar to these kings that a group might want to fight are the King Black Dragon and the Kalphite Queen.
