Dagannoth Rex is one of the three Dagannoth Kings found on Waterbirth Island in Old School RuneScape (OSRS). These bosses are popular for their valuable drops, especially the unique Rex pet, the Dagannoth Kings' rings, and the seercull bow. However, many players find the fight challenging, especially when attempting to solo Dagannoth Rex.

 

This comprehensive guide will take you through everything you need to know to successfully solo Dagannoth Rex-from preparation and gear recommendations to combat strategies and tips to maximize your chances of success.

 

What is Dagannoth Rex?

Dagannoth Rex is the melee-based Dagannoth King, located in the same lair as Dagannoth Prime (magic) and Dagannoth Supreme (ranged). The trio lives in a cave beneath Waterbirth Island, accessible via a combination of boating and navigating a dungeon.

 

Rex is known for his powerful melee attacks and high defense. Unlike Prime and Supreme, Rex primarily attacks using melee combat, though he also has a lesser magical attack. His defense is focused against melee, so using ranged or magic attacks can be effective.

 

Why Solo Dagannoth Rex?

Most players kill the Dagannoth Kings as a group because of the difficulty and the high damage potential of each boss. However, soloing Rex can be rewarding and a great challenge for skilled players. You will get more OSRS gold.

 

Benefits of Soloing Rex

Valuable Drops: Rex drops the Dagannoth Kings' rings, which are useful for their combat bonuses and teleport abilities.

 

Pet Chance: The Rex pet is a coveted cosmetic addition and a sign of bossing prowess.

 

Skill Improvement: Soloing Rex hones your combat mechanics, agility, and resource management.

Recommended Combat Level and Stats

Combat Level: 90+ recommended.

Prayer: 52+ (for Protect from Melee and access to Piety or Rigour).

Gear Setup

The ideal approach to soloing Rex is to use ranged attacks combined with Protect from Melee prayer to avoid his melee hits.

Twisted Bow (best in slot if you have it).

 

Blowpipe with steel or better darts.

 

Rune Crossbow with broad bolts or better.

 

Magic Shortbow with special attack (optional).

Karil's leathertop and skirt for prayer bonus and ranged defense.

 

Armadyl armor or Void Ranger gear for damage bonuses.

 

Ava's assembler or Ava's accumulator for ranged ammo recovery.

 

Accessories

Amulet of Fury or Necklace of Anguish (if you have it).

Boots and Gloves

Pegasian boots or Ranged boots.

 

Barrows gloves for best-in-slot melee/ranged bonuses.

 

Inventory Setup

Here's a typical inventory setup for soloing Dagannoth Rex:

 

Super combat potion or Ranging potion.

 

Prayer potions (4-5 depending on your prayer level).

 

Food: Sharks, manta rays, or better (like anglerfish).

 

Teleport tab or teleport runes (to escape quickly if needed).

 

Saradomin brew and Super restore combo (if you want safer healing).

 

Rune pouch with useful runes (optional for magic gear swaps).

 

Stamina potion (optional, for quick movement).

 

Accessing Dagannoth Kings

To reach Dagannoth Rex, you need to:

 

Travel to Waterbirth Island.

 

Use the canoe system in Rellekka to reach the island.

 

Enter the Dagannoth Kings' lair through the dungeon under the island.

 

Inside, you'll see three Dagannoth Kings: Rex, Prime, and Supreme.

 

Combat Strategy: How To Fight Dagannoth Rex Solo

Step 1: Prayer and Positioning

Upon entering the lair, immediately activate Protect from Melee prayer. Rex's primary attack style is melee, so this prayer drastically reduces damage taken.

 

Position yourself so that Rex is the only king attacking you; avoid aggroing Prime and Supreme if possible.

 

Step 2: Use Ranged Attacks

Attack Rex using your ranged weapon from a distance.

 

Keep moving slightly to avoid his occasional magic attacks.

 

Use special attacks if available (e.g., Magic Shortbow special) to maximize damage output.

 

Step 3: Manage Prayer and Health

Monitor your prayer points carefully; bring enough prayer potions to keep Protect from Melee active throughout.

 

Use food as needed to heal from any damage taken.

 

Use Saradomin brews and super restores to quickly heal if you have them.

 

Step 4: Use Safe Spots if Possible

There are some safe spots in the lair where Rex cannot hit you with melee attacks, especially when fighting from staircases or behind obstacles.

 

Using safe spots minimizes damage and conserves food and prayer.

 

Tips for Success

Focus on One King at a Time: Aggro only Rex at first. You can kill him before worrying about Prime and Supreme.

 

Bring High-Quality Food: Sharks and better ensure you survive unexpected hits.

 

Use a Prayer-Boosting Necklace: Like the Amulet of Fury or Necklace of Anguish to extend prayer duration.

 

Practice Timing: Learn the attack patterns of Rex to better anticipate his melee and magic attacks.

 

Stay Calm: Rex can hit hard if you mess up prayer timing, but with practice, it becomes easier.

 

Use Protect from Melee Efficiently: Keep it on at all times, but toggle off briefly to conserve prayer if safe.

 

Try with Friends First: Practice killing Rex in a duo or group to get a feel for mechanics before soloing.

 

Keep an Eye on Special Attacks: Rex occasionally uses a magic attack that can bypass melee protection, so be ready to eat or switch prayers if necessary.

 

What to Do After Killing Rex

Once you successfully kill Dagannoth Rex:

 

Loot his drops quickly; his drop table includes valuable items such as:

 

Dagannoth Kings' rings

 

Seercull (unique ranged weapon)

 

Rune and Dragon equipment

 

Dagannoth bones and sharks

 

Use the Ring of Wealth or Ring of the Gods (if imbued) to increase the chance of rare drops and buy OSRS gold.

 

Common Mistakes to Avoid

Not Using Protect from Melee: This drastically increases the chance of dying quickly.

 

Aggroing All Three Kings: Trying to fight all three solo without preparation is nearly impossible.

 

Underestimating Food and Prayer Needs: Bring enough supplies to last the fight.

 

Standing Still: Rex has fast melee attacks; moving around can reduce damage taken.

 

Ignoring Safe Spots: These can reduce damage taken and increase survivability.

 

Final Thoughts

Soloing Dagannoth Rex in Old School RuneScape is a challenging but rewarding endeavor. It requires good gear, careful preparation, and solid combat skills, especially in managing prayer and positioning. Once mastered, soloing Rex can be a lucrative source of unique items and boss pets.

 

Remember to take your time learning the fight mechanics, practice with friends or in groups, and gradually build up your confidence and equipment. With persistence, you'll soon be a solo Dagannoth Rex expert.
