Dagannoth Rex Best in Slot Gear & Strategy Guide

AKA - DKs

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.

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.

Dagannoth Rex — Frequently Asked Questions

What is the Best in Slot gear for Dagannoth Rex in OSRS?

The Best in Slot setup for Dagannoth Rex depends on your combat style and budget. The gear grid above shows the top-ranked items for each equipment slot — sorted by the stats that matter most for this fight (accuracy vs. max hit vs. defence). For most players, near-BiS gear (one tier below the absolute top) clears dagannoth rex comfortably without needing a max-stake bank.

Look at the inventory recommendation below the gear list for prayer potions, food, and any boss-specific items you should bring.

What stats do I need to fight Dagannoth Rex?

Check the "Requirements" line at the top of this guide — it lists the recommended combat stats and quest prerequisites. As a general rule, you can engage dagannoth rex at the listed minimums, but expect slower kills and more food consumption. Higher combat stats (especially Strength, Ranged Strength, or Magic Damage % depending on the style) translate directly to faster, safer kills.

If your stats are below the recommended minimums, consider training at easier slayer tasks first — efficiency goes up dramatically once you can actually use BiS gear effectively.

Do I need full BiS gear to kill Dagannoth Rex?

No. Full BiS makes kills faster but is rarely required. Most players clear dagannoth rex with mid-to-high tier gear — the difference between a Bandos chest and Torva, or a Trident and Shadow, is typically 5-15% DPS. That matters at endgame raid speeds; it doesn't matter for slayer or casual PvM.

Use the BiS gear above as your aspirational target, but start with what you have. The boss tells you what works through your kill speed and food usage.

How do I get to Dagannoth Rex?

Travel to Dagannoth Rex varies by boss. Check the OSRS Wiki for the exact teleport or walking path — most bosses have a fairy ring code, a slayer master teleport, or a quest reward teleport that works. Bring a way back to the bank between trips: skull-tricks, Achievement Diary teleports, or a House teleport are common.

If you're fighting Dagannoth Rex on a slayer task, your slayer master's teleport will usually drop you right at the lair entrance.

What are the best drops from Dagannoth Rex?

The "Notable Drops" section above lists the top items from Dagannoth Rex — the ones most players are actually grinding for. Most boss tables include a unique (the most valuable rare drop), a handful of mid-tier uniques, and a steady stream of GP-value drops like alchables, runes, and crafting materials.

Drop rates and exact loot tables come from the OSRS game data; specific roll mechanics (1/X, scales with kill count, etc.) vary boss-to-boss — check the OSRS Wiki for full drop tables and rate-of-return calculations.

How do I afford Dagannoth Rex gear?

Most BiS items for dagannoth rex come from raids (Tombs of Amascut, Theatre of Blood, Chambers of Xeric) or specific bosses you'd need to grind separately. The Grand Exchange shortcuts the grind for tradeable items: BiS gear costs anywhere from a few million to a few billion GP per piece.

If you want to skip the gold-grind and buy gear directly, Probemas sells OSRS gold safely — pick it up at the GE the same hour and you're back killing dagannoth rex with proper gear.

How much DPS will my setup do against Dagannoth Rex?

Use our OSRS DPS Calculator to find out. Load your stats from the hiscores, equip your gear, pick Dagannoth Rex as the target, and the calculator shows your max hit, hit chance, and DPS across melee, ranged, and magic so you can see which style wins for this fight.
