Burning Axe

A Burning Axe is an  Axe-class Artifact weapon found in. It is a Mars-based pure-element weapon, meaning that its regular attack is counted as an elemental physical attack that is affected by the wielder's Mars Power and the target's Mars Resistance.

The Burning Axe is one of the prizes that can be won in the Lucky Medal Fountain in Tolbi. As an Axe, it can be equipped by Isaac and Garet. A Burning Axe's Unleash attack is Broil. Broil converts all damage to Mars damage and attacks with an additional 23 damage points; unlike the other Axe artifacts in Golden Sun, including the earlier Vulcan Axe, the Burning Axe may be faulted for not having an additional effect to its unleash. Visually, Broil resembles a normal strike with a red cloud spreading out upon impact.

Like Assassin Blades, weapons stronger than Burning Axes aren't found until Lunpa (except for the other weapons from the spring). The Burning Axe is actually the weakest weapon available from the spring, but it is still stronger than any other weapons up to this point, except for the Mystery Blade, which is just as powerful but requires players to veer off course and land on Crossbone Isle. Since all attacks with this weapon are Mars-based, it will always do enhanced damage to monsters with low Mars Resistance, most notably Toadonpa and all the Mimics.

If the Burning Axe were to be transferred to, Felix and Piers could equip it as well.
