Vulcan Axe

The Vulcan Axe (Smog Axe in Japan) is an axe found in Golden Sun. It is found in a hidden chest early on in Lamakan Desert that can only be seen (and opened) if Reveal is used near it, and the chest is located in an area that otherwise appears to be a dead-end. Being an axe, it can be equipped by Isaac, Felix, Garet, and Piers. It can be bought for 4600 coins and sold for 3450 coins.

The Vulcan Axe increases the wielder's base Attack rating by 76, and is noteworthy for being a weapon that always converts its normal attack's would-be damage from physical to Mars; most weapon artifacts only convert their attacks to an element when their respective Unleash effects are triggered. Its Mars-based Unleash effect, activating at the standard base rate of 35% of the time, is Barrage (Explosion in Japan), which adds another 20 base attack points to the attack and attempts to stun the target. Barrage appears as the axe strike creating an intense explosion of flame with a few sparks being emitted.

The Vulcan Axe, as is typical of many weapon artifacts, is easily the best weapon the party has when it can first be collected. It is one of a scant few weapons in either game whose normal attacks convert to an element, which means its damage is easily affected by enemy resistances. Watery monsters, or more precisely any monster with a low Mars resistance rating, will always receive enhanced damage from this axe whether it Unleashes or not, making it a great weapon to use in the boss fight with the Kraken a little later on, and its damage increases if its wielder has a higher Mars power rating. Garet is typically a strong candidate for holding the axe, but so is Isaac if two Mars-based attackers is better in a particular battle, and particularly if Isaac has Mars Djinn set onto him to make his class of the Brute class series.
