Barrelchest

Barrelchest is a giant robot made out of barrels, controlled by a brain in a glass dome. It's got various piratical items like a ship's wheel and other items attached to it, and it uses an anchor as a weapon. Prayer cannot be used during the battle. Barrelchest will attempt to hit you directly with his anchor, but if he can't get to you, he will slam his anchor into the ground, causing an earthquake, which instantly does around 20 damage. If you can defeat Barrelchest, he will drop his weapon, the Barrelchest Anchor.
