OSRS Dagannoth Rex Solo Guide

OSRS Dagannoth Rex Solo Guide

Soloing Dagannoth Rex in Old School RuneScape (OSRS) is an exciting challenge that offers players a chance to earn valuable rewards like the Berserker Ring, Warrior Ring, and Dragon Axe. As the melee-based Dagannoth King located in the Waterbirth Island Dungeon, Rex is the easiest of the trio to solo due to his low Magic Defence and the ability to safespot him. This comprehensive guide will walk you through everything you need to know to successfully solo Dagannoth Rex, including preparation, strategies, and gear setups, optimized for players with mid-level stats.

Dagannoth Rex is a popular boss for solo players due to his manageable mechanics and high-value drops. With the right setup, players can achieve long trips with minimal supply usage, making it an excellent choice for Slayer tasks or profit-driven bossing. Here’s why you should consider soloing Rex:

  • Valuable Drops: Rex drops the Berserker Ring (1/128 chance, worth ~3M GP) and Warrior Ring (1/128, ~80k GP), alongside the rare Dragon Axe.
  • Slayer Task Efficiency: Dagannoth tasks are common, and killing Rex can yield significant profit and experience.
  • Low Requirements: With combat stats around 70, players can tackle Rex effectively.
  • Safespot Advantage: Rex can be lured to a safespot, minimizing damage taken.

Recommended Stats and Requirements

To solo Dagannoth Rex efficiently, aim for the following stats:

  • Combat Level: 100+ for a comfortable experience.
  • Magic: 70+ (50 minimum for basic spells like Iban’s Blast).
  • Defence: 70+ to wear Barrows armor and tank Spinolyps.
  • Prayer: 43+ for Protect from Magic; 45+ for Mystic Might.
  • Hitpoints: 60+ to survive incidental damage.

Quest Requirement: Complete The Fremennik Trials to access Waterbirth Island. The Elite Fremennik Diary is highly recommended for noted bone drops, increasing profitability.

Gear Setup

Rex has extremely low Magic Defence, so you can prioritize high Ranged Defence and Prayer bonuses to mitigate Spinolyps’ attacks and sustain Prayer. Below is a recommended gear setup for mid-level players:

Slot Item Alternative
Head Slayer Helmet (if on task) Serpentine Helm (poison immunity)
Cape Ardougne Cloak God Cape
Neck Occult Necklace Amulet of Fury
Body Guthan’s Platebody Torag’s Platebody
Legs Guthan’s Chainskirt Verac’s Plateskirt
Weapon Trident of the Seas Iban’s Staff (u)
Shield Crystal Shield Book of Darkness
Gloves Barrows Gloves Combat Bracelet
Boots Dragon Boots Rune Boots
Ring Ring of Suffering Ring of Wealth

Notes: Guthan’s set is ideal for healing off Spinolyps between Rex spawns, extending trips. The Serpentine Helm eliminates the need for Antipoison but is costly (~3.4M GP). If on a Slayer task, the Slayer Helmet boosts damage and accuracy.

Inventory Setup

Your inventory should balance combat sustainability and dungeon navigation. Here’s a suggested setup:

  • Rune Thrownaxe (1-2): Required to enter the Dagannoth Kings’ lair solo.
  • Pet Rock: Used to open the dungeon gate solo (requires Fremennik Trials).
  • Prayer Potions (4-6): Essential for low Defence players to maintain Protect from Magic.
  • Antipoison++ (1-2): Counters Spinolyps’ poison (not needed with Serpentine Helm).
  • High-Healing Food (10-15): Sharks or Karambwans for emergency healing.
  • Teleport (1): House teleport or Ectophial for quick escapes.
  • Runes: For your chosen spell (e.g., Iban’s Blast, Blood Barrage) or Trident charges.
  • Optional: Saradomin Brews and Super Restores for extended trips.

Navigating to Dagannoth Rex

Getting to Waterbirth Island

Start by traveling to Rellekka (use a House Teleport if your house is there, or the Enchanted Lyre). Speak to Jarvald at the Rellekka docks to take a boat to Waterbirth Island. Ensure you have completed The Fremennik Trials to access this route.

Entering the Dungeon

The Waterbirth Island Dungeon is perilous, so follow these steps to reach the Dagannoth Kings’ lair:

  1. Enter the dungeon via the ladder west of the island.
  2. Use the Rune Thrownaxe on the door supports and drop the Pet Rock to open the gate solo.
  3. Navigate through the dungeon, using Protect from Ranged or Magic in rooms with aggressive Dagannoths.
  4. Reach sublevel six, where the Dagannoth Kings reside.

Tip: Memorize the dungeon path and use Energy Potions to reduce run energy depletion.

Combat Strategy for Dagannoth Rex

Entering the Lair Safely

The hardest part of soloing Rex is entering the lair without aggroing Dagannoth Prime (Magic) or Supreme (Ranged). Follow these steps:

  1. Activate Protect from Magic before descending the Kings’ ladder to mitigate Prime’s high-damage attacks.
  2. Spam-click the ladder to “peek” and check the positions of Prime and Supreme. If they’re close, climb back up to avoid damage.
  3. Once safe, run to the south-eastern corner of the lair, hugging the eastern coastline to avoid Supreme’s aggro.

Pro Tip: If another player is already safespotting Rex, switch worlds to avoid Prime’s area-of-effect attacks.

Safespotting Rex

Rex can be safespotted by luring him to the eastern wall:

  1. Attack Rex with a long-range Magic spell (e.g., Trident on Longrange mode).
  2. Run to the eastern coastline and wait for Rex to approach.
  3. Move south or north until Rex gets stuck on a ridge or wall, rendering him unable to melee you.
  4. Continue attacking with Magic while staying in the safespot.

Note: Spinolyps will still attack with Ranged-based Magic and poison, so keep high Ranged Defence gear equipped and sip Antipoison as needed.

Managing Spinolyps and Sustaining Trips

Spinolyps in the moat surrounding the lair deal minor damage but can poison (starting at 6 damage) and drain Prayer points. To manage them:

  • Heal with Guthan’s: Attack Spinolyps with Guthan’s set effect to heal between Rex spawns.
  • Blood Spells: Use Blood Barrage or Blood Blitz to heal, though this requires higher Magic levels and runes.
  • Saradomin Godsword: If affordable, use its special attack to heal and restore Prayer.
  • Antipoison: Sip Antipoison++ to counter poison; one dose lasts 12 minutes.

With high Defence (90+), you may take minimal damage from Spinolyps, allowing near-infinite trips with Guthan’s or Blood Spells.

Loot and Profit Potential

Drop Table Highlights

Rex’s drops make him a profitable boss. Key items include:

  • Berserker Ring: 1/128 chance, ~3M GP.
  • Warrior Ring: 1/128 chance, ~80k GP.
  • Dragon Axe: 1/128 chance, valuable for Ironmen.
  • Dagannoth Bones: 100% drop, ~9k GP each (noted with Elite Fremennik Diary).
  • Runes, Seeds, and Herbs: Common drops for extra profit.

Average Kill Value: ~54,797 GP (or ~56,470 GP on a Konar Slayer task). Excluding ring drops, ~18,575 GP per kill. Expect 15-28 kills per hour, yielding 700k-1M+ GP/hour.

Maximizing Profits

To boost your earnings:

  • Elite Fremennik Diary: Noted bones significantly increase profit per trip.
  • Ring of Wealth: Removes “nothing” drops, slightly improving drop table odds.
  • Telekinetic Grab: Loot drops safely if Rex dies far from the safespot.
  • High Alchemy: Bring Nature Runes to alch low-value drops for extra GP.

Tips and Common Mistakes to Avoid

Pro Tips for Success

  • World Hopping: Use the safe-spot near the ladder to check for other players and hop worlds if needed.
  • Prayer Management: Only use Protect from Magic when entering or if Prime aggros; Mystic Might boosts Magic damage.
  • Inventory Space: Save space by alching junk or burying bones (without Elite Diary).
  • Backup Supplies: Keep extra Pet Rocks and Rune Thrownaxes in your bank for quick recovery after death.

Common Mistakes

  • Aggroing Other Kings: Venturing too far west risks Prime or Supreme attacks. Stay in the south-eastern corner.
  • Neglecting Spinolyps: Ignoring poison or low Prayer can drain supplies quickly.
  • Poor Safespot Setup: Ensure Rex is fully stuck before attacking to avoid melee damage.
  • Overloading Inventory: Bring only essential supplies to maximize loot space.

Soloing Dagannoth Rex is a rewarding and accessible bossing activity in OSRS, perfect for mid-level players looking to earn profit or complete Slayer tasks. With the right gear, a solid safespot strategy, and careful management of Spinolyps, you can enjoy long, profitable trips. Whether you’re chasing the Berserker Ring or simply want a fun challenge, this guide equips you to tackle Rex with confidence. Happy bossing!
