OSRS Dagannoth Kings Guide: DKs Tribrid Strategy & Rotation

Dagannoth Kings at a Glance

The Dagannoth Kings (DKs) are three level 303 bosses sharing one multiway room on the deepest level of Waterbirth Island Dungeon, and each one covers a corner of the combat triangle. Kill Dagannoth Rex with magic, Dagannoth Prime with ranged and Dagannoth Supreme with melee, and never let two of them attack you at once. Killing all three in one trip is called tribrid. Most players start with Rex alone from a safespot.

Each King has 255 hitpoints, attacks every 4 ticks and respawns 90 seconds after dying. Each has two unique drops at 1/128, and all three drop the dragon axe at 1/128 and a pet at 1/5000. Dagannoth bones and a dagannoth hide come with every kill.

Requirements and Getting In

There is no quest requirement for the Dagannoth Kings. Horror from the Deep is not needed. The real gate is the route through Waterbirth Island Dungeon:

• At the end of the first cavern, two pressure pads need two players. Solo, put a pet rock on one. Askeladden gives you one during or after The Fremennik Trials.
• Three door supports guard the central room. From the north or south path, a rune thrownaxe special attack on the middle (western) support bounces through all three.
• 85 Agility lets you climb the rocks south of Jarvald straight to the cave entrance by the ladder room, skipping the pet rock and thrownaxe. A summer pie boosts 80 to 85.
• An 81 Agility crevice past the first giant rock crabs is a one-way shortcut to the room before the Kings.
• Jarvald sails from Rellekka for 1,000 coins a trip, or free after The Fremennik Trials.

The fastest ways to the island are the Lunar Waterbirth Teleport, a POH portal or nexus, or an enchanted lyre after the Hard Fremennik Diary. The run down is long, so carry a stamina potion or an explorer's ring, and use the safe room by the Kings' ladder to restore and peek through the crack before you go in.

Aim for 70+ Attack, Strength, Ranged and Hitpoints, 75+ Magic, at least 60 Defence (80+ is better), 45 Prayer for Mystic Might and 70 for Piety. The boss requirements checklist lists gates for the other bosses.

Where the Dagannoth Kings Fit in Progression

Within the standalone boss group, the fights below the Dagannoth Kings are Barrows brothers and Deranged Archaeologist. Above them sit Corporeal Beast and The Nightmare.

DKs Strategy: The Tribrid Rotation

Every rotation exists to stop two Kings hitting you at once. Aggression ranges are counted from each King's south-west tile: 5 tiles for Rex, 7 for Prime and Supreme. Rex can be stuck on the north-east, south-east or north-west walls, Prime can be shot from the north side with a long-range weapon, and Supreme has to be meleed close to the other two.

Protect from Magic goes on before you climb down, because Prime hits hardest and Prime or Supreme usually target you on landing. If they do, climb straight back up and retry.

Safe rotation

1. 1

   Land with nothing on you and run counter-clockwise along the south wall to the east side.

2. 2

   Safespot Rex on the east wall and kill him with magic.

3. 3

   Move north and range Prime from the north wall.

4. 4

   Head south-west and melee Supreme, staying as far west as you can so a respawned Rex cannot reach you.

5. 5

   Back to the east wall for Rex, and repeat.

Faster rotation (strong gear)

1. 1

   Land and melee Supreme first, praying against Prime if he notices you.

2. 2

   Magic Rex while dragging him to the north-west safespot.

3. 3

   Range Prime from the north side, away from where Supreme respawns.

4. 4

   Melee Supreme again, staying north and west, away from Rex.

5. 5

   Rex on the north-west safespot again.

Kill Supreme after Prime so the two long-range Kings are never on you together. With very high Defence and armour, Rex and Supreme only land 15 to 30% of their attacks, so some players run in with Protect from Magic, tank both while killing them, then swap to ranged armour for Prime. The Dagannoth Rex guide shows exactly how to trap Rex on the wall.

DKs Tribrid Setup and Inventory

Tribrid means carrying a melee, a ranged and a magic switch. Because the walk in is so long, give up some damage for supplies and try to finish a whole Slayer task in one trip. Barrows gloves instead of ferocious gloves plus zaryte vambraces, or a spectral spirit shield instead of a defender, are typical trades.

• Ranging potions and super combat potions.
• Super restores or sanfew serums. Spinolyp magic hits drain prayer, and their ranged hits poison, starting at 6.
• A few sharks or anglerfish and a Saradomin brew.
• A rune pouch with blood and ice spell runes.
• A stamina potion or explorer's ring for the run, and a herb sack for grimy ranarr weed.
• A rune thrownaxe and pet rock, unless you use the 85 Agility shortcut.

Dagannoth Kings Drop Rates

All the uniques are 1/128: berserker and warrior rings from Rex, seers ring and mud battlestaff from Prime, archers ring and seercull from Supreme. Each King rolls the dragon axe separately at 1/128, so a full rotation gives you three chances at it. Hard clues are 1/42 and elite clues 1/750 from every King. Bones drop noted once you finish the Elite Fremennik Diary, which itself needs a kill of each King.

Combat Achievements

Each King has a Champion task (10 kills, Medium) and an Adept task (25 kills, Hard). The Elite tasks need the whole room: Rapid Succession (all three Kings dead within 9 seconds of the first), Toppling the Diarchy (Rex and another King at the exact same time), From One King to Another (kill Prime with a rune thrownaxe special bounced off Rex), and the three Death to the Warrior, Seer and Archer King tasks, each killing one King while the other two attack you. Rex also has A Frozen King at Medium: kill him while he is immobilized.

Slayer and Ironman Notes

Dagannoth tasks from Vannaka, Chaeldar, Konar, Nieve and Duradel count. Use the ladder's Slayer option for the task-only lair, where only players on task can damage the Kings. Rex and Prime give 331.4 Slayer XP each, Supreme 255.

Ironmen usually come for one ring at a time: berserker ring from Rex, archers ring from Supreme, seers ring from Prime. None of them drop anywhere else.

Common Mistakes and Death Causes

• Climbing down without Protect from Magic. Prime hits up to 50.
• Pulling Rex too far west and bringing Prime and Supreme into the fight.
• Starting on Supreme while Prime is already aggressive.
• Keeping Protect from Missiles on after Prime respawns.
• Skipping antipoison. Supreme and the Spinolyps both poison.
• Bringing so many switches that you run out of restores after a handful of kills and have to walk all the way back.
