Barrelchest anchor

The barrelchest anchor is obtained by killing the Barrelchest monster in The Great Brain Robbery quest. You need 60 Attack and 40 Strength to wield it. The anchor's stats are almost equal to Dharok's greataxe. Upon completion of The Great Brain Robbery the player must pay 230k to repair the anchor in order for it to be used as a weapon after purchasing a broken anchor from Brother Tranquility. The anchor can be repaired by Smith on the docks of Mos Le'Harmless. Note that Book o' piracy is needed to properly speak with Smith. Alternatively, players can purchase one from Perdu for 290,000 coins.

The barrelchest anchor is mostly known as a PKing weapon, used in combos such as anchor to Granite maul specials. The reason why this particular combo is so effective is due to the fact that the anchor has a delayed hit, allowing it to easily stack with the maul's two blows.

If lost, it can be re-obtained by talking to the monk, Brother Tranquility, on Mos Le'Harmless to receive another broken anchor which can once again be fixed by Smith for 230,000 coins. The book o' piracy is required in order to communicate with Smith.

Special attack
The barrelchest anchor has a special attack, Sunder, which doubles the player's accuracy, increases max damage by 10%, and lowers the opponent's Attack, Defence, Ranged or Magic level by 10% of the damage dealt. If the opponent's defence level is 1, it drains attack instead. This consumes 50% of the player's special attack energy.

Sunder drains one stat at a time by 10% of the damage dealt. Moves to next stat if stat that is being compared is <=1. Order Defence, Attack...
