Barrelchest

Barrelchest is a giant robot created by evil surgeon Mi-Gor made from barrels, other nautical objects, and at least one brain. It is the final opponent in the The Great Brain Robbery quest. It is controlled by a brain with eyes floating in an unknown liquid 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. 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.

Strategy

 * This battle is also covered in the Great Brain Robbery article.

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 (long range attack) which may deal up to 250 life points. It drains some of your Prayer with every hit, and can also disrupt prayer entirely. Barrelchest will also drain your Defence so defence potions or restore potions are strongly recommended. Another possible way of defeating Barrelchest, especially for combat pures with low Defence, is to use a combination of Ice and Blood spells from the Ancient Magicks spellbook to minimise damage taken. A Magic level of 82 is recommended in order to have access to Ice Blitz and Blood Blitz. Some players use Ranged for this fight, attacking from behind pews. Unfortunately this will not avoid damage, as due to Barrelchest's long-ranged attack. For melee, a weapon with a strong crush attack (a mace, battleaxe or maul, for example) is recommended. Good food is recommended for any combat style, due to Barrelchest's powerful combination of strong attacks, long range, and the ability to both drain prayer points and disrupt protection prayers. Now that quick prayers have been added set them to protect from melee and activate them every time they're deactivated. Bring 2-3 prayer potions in case he lowers them too much.

Trivia
Barrelchest Note if you need to get to your gravestone you will still need diving gear so it is suggested you have another pair ready.
 * This boss was updated on 2 June 2009. The update eliminated some common methods of defeating Barrelchest with Ranged or Magic without taking damage.
 * It should be noted that a ring of life will not protect you from death if you are to die fighting Barrelchest. Your gravestone will appear outside of the church.
