Barrelchest

Barrelchest is a giant robot made from barrels. It is the final opponent in the The Great Brain Robbery quest. It is controlled by a brain in a glass dome. Attached to it are various nautical objects like a ship's wheel and a life-ring, and it uses an anchor as a weapon. Barrelchest will attempt to hit players directly with its anchor, but if it can't reach the player, it will slam its anchor into the ground, causing an earthquake which may deal up to 25 damage. It drains some of your prayer with every hit, and can also disrupt prayer entirely. Barrelchest is also known to drain one's defence. When the player defeats Barrelchest, it will drop its weapon, the Barrelchest anchor, which will be broken and can be repaired for 230,000gp by talking to the pirate Smith on the south docks of Mos Le'Harmless. Once repaired it can be used as a slow but powerful melee weapon.
