About The Great Brain Robbery

The Great Brain Robbery is the third quest in the Pirate series. Brother Tranquility on Mos Le'Harmless asks for help reclaiming Harmony Island from zombie pirates led by Mi-Gor, who have stolen the monks' brains. You first secure the windmill by pulling a statue, traversing an underwater tunnel (requiring Diving apparatus & Fishbowl helmet), repairing stairs, and peeking through a peephole. Next, retrieve a Prayer book from the Edgeville Monastery to dispel poison gas. To recruit Dr. Fenkenstrain for brain surgery, you must smuggle him off the mainland by crafting 10 Wooden cats (or buying them), building a decoy crate at his castle, and using a Wolf whistle obtained from Rufus in Canifis (charmed with Ring of Charos). Once Fenkenstrain arrives on Harmony, you gather surgical tools by killing 4 Sorebones (Level 57) in the island's monastery after blowing open the door with a Keg of powder. After Fenkenstrain performs the 'surgery', you confront Mi-Gor, who summons the Barrelchest (Level 190) boss. Defeating it completes the quest.

Frequently Asked Questions

Approximately 1 to 1.5 hours. It involves significant travel (Mos Le'Harmless, Harmony, Monastery, Canifis, POH potentially), item crafting, puzzle elements, and combat.

Fishbowl helmet, Diving apparatus, 10 Wooden cats (tradeable) OR 10 planks/10 fur/hammer/saw/Clockmaker's bench access, Hammer (not Imcando), ~100 Nails, 8 Planks, Holy symbol, Ring of charos. Combat gear, food, Prayer potions for Sorebones (Level 57) and Barrelchest (Level 190) are essential. A Tinderbox, Keg of powder, and Fuse are obtained during quest steps.

Barrelchest (Level 190) uses only Melee but hits very hard (max hit >20). It drains Prayer faster than usual and can disable prayers. Safespotting with Range/Mage is highly recommended. Melee requires high stats, good gear, food, and potentially prayer potions.

No, the OSRS Wiki states Crafting (16), Construction (30), and Prayer (50) requirements are NOT boostable.

It's a powerful two-handed crush weapon requiring 60 Attack and 60 Strength. It needs a 230k coin repair from Smith on Mos Le'Harmless docks (requires Book o' piracy) after the quest before it can be wielded.

Yes, but they MUST provide all combat gear/supplies. They will also need access to a POH workshop/crafting table (or use another player's) and gather materials (planks, fur, nails) if crafting the Wooden cats themselves instead of buying them.

Still not sure? We’ll walk you through it live.
