Step-by-Step Quest Walkthrough

The Great Brain Robbery is a multi-stage quest that involves traveling between Harmony Island and Mos Le’Harmless, solving puzzles, and facing off against foes. Follow this detailed walkthrough to complete it efficiently.

Starting the Quest

Begin by speaking to Brother Tranquility on Mos Le’Harmless. You’ll find him near the docks, looking distressed. He’ll explain that the monks of Harmony Island are in trouble—zombie pirates have stolen their brains! Agree to help, and you’re off to the races.

Investigating Harmony Island

Use your Ectophial or Fairy Ring (D-I-P) to teleport to Harmony Island. Speak to Brother Tranquility again (he teleports with you) and enter the monastery. Inside, you’ll discover the monks have had their brains swapped with those of zombie pirates, thanks to the evil Mi-Gor. Your task? Fix this mess.

Crafting the Prayer Book

To proceed, you’ll need a special prayer book. Head to the Edgeville Monastery or Crafting Guild to obtain a Holy Book. Then, craft a prayer book by combining it with a holy symbol. This item will protect you later, so don’t skip this step!

Repairing the Monastery

The monastery’s defenses are down, and you’ll need to repair them. Use your 10 oak planks, hammer, and nails to fix the walls. Once done, talk to Brother Tranquility again to move forward.

Confronting the Zombie Pirates

Now it’s time to face the culprits. Travel back to Mos Le’Harmless and head to the windmill. Use your prayer book to recite prayers and fend off zombie pirates (level 57). After defeating them, enter the basement and prepare for a showdown with Barrelchest (level 190).

Combat Strategies for Barrelchest

The fight against Barrelchest is the climax of The Great Brain Robbery. This mechanical monstrosity hits hard, so preparation is key.

Barrelchest Stats and Attacks

Barrelchest boasts 134 Hitpoints and uses melee attacks that can drain your Prayer points. Without a strategy, you’ll be sunk faster than a leaky ship.

Recommended Gear

Here’s what to bring to the fight:

  • Rune armor or better – For solid defense.
  • Prayer potions – To counter Prayer drain.
  • High-damage weaponDragon scimitar or better recommended.
  • Food – Sharks or monkfish to stay alive.

Fight Tactics

Use Protect from Melee to mitigate damage. Keep your Prayer topped up with potions, and hit Barrelchest hard and fast. If your Hitpoints drop, eat food to stay in the fight. With persistence, you’ll dismantle this pirate contraption.

Rewards and Benefits

Completing The Great Brain Robbery isn’t just about saving monks—it’s also about reaping the rewards. Here’s what you’ll gain.

Quest Points and Experience

Upon completion, you’ll receive:

  • 2 Quest Points – Boosting your total.
  • 6,000 Prayer XP – A hefty chunk toward your next level.
  • 10,000 Crafting XP – Great for mid-level crafters.
  • 2,000 Hitpoints XP – Useful for combat training.

Unlockable Items

You’ll also unlock the Barrelchest anchor, a two-handed weapon with a +100 Strength bonus and a special attack that boosts your attack speed. It’s a fun addition to your arsenal, though not top-tier for endgame content.

Additional Perks

Gain access to the Harmony Island Teleport spell (requires 65 Magic and the Morytania Hard Diary) and the ability to bless other players’ holy symbols remotely. These perks add convenience to your OSRS adventures.

Tips and Tricks for Success

To make The Great Brain Robbery a breeze, keep these pointers in mind.

Efficient Travel

Use teleports like the Ectophial and Fairy Rings to cut down on travel time. Stock up on teleport items before starting to avoid mid-quest delays.

Combat Preparation

Over-prepare for Barrelchest—bring extra food and potions. The Prayer drain can catch you off guard if you’re not ready.

Item Management

Bank unnecessary items before heading to Mos Le’Harmless. You’ll need inventory space for quest-specific items like the prayer book and oak planks.
