Captain's Axe

The Captain's Axe is an Axe-class weapon found in Golden Sun: The Lost Age. Visually, it resembles a one-bladed axe with a second, much smaller red blade or flag on top of the main blade facing the opposite direction.

In
It is acquired by finding a Rusty Axe in a white spot of sea southeast of Lemuria in the Great Eastern Sea, then bringing it to Sunshine the Blacksmith in the town of Yallam in Osenia down south and letting him reforge it with his “elbow grease”. The player will then have to buy the Axe from Sunshine. As an Axe, it can be equipped by Felix and Piers. Once Isaac and Garet join the party, they can equip the Captain's Axe as well.

Unlike many Artifact weapons, the Captain's Axe does not have an Unleash effect; instead, it has a Use effect which emulates the Guard Psynergy to boost the defense of an ally by 25% of the character’s total defense (and it can be used again to raise the defense to the maximum value of 50%). It has a chance of “breaking” when its effect is used enough times, but it can still be used for battle regardless.

It is a moderately powerful axe for when it can be first found, which is right after Felix's party gets Piers' Lemurian Ship, but it is rarely used at that point because it does not have an Unleash effect, and there are better weapons available at that point in time.
