Demon Mace

The Demon Mace is a Mace-class weapon found in Golden Sun: The Lost Age. It is found as a Rusty mace in the interior portion of Gaia Rock, and it must be reforged by Sunshine the blacksmith in Yallam and then bought from him to be properly obtained. Being a Mace, it can be equipped by Isaac, Felix, Garet, Sheba, Mia, and Piers. Its buy value is 9200 coins and its sell value is 6900.

The Demon Mace increases the wielder's attack by 115. The Demon Mace's Unleash effect is Evil Eye, which is effectively a standard physical attack that adds 38 damage points and then modifies the resulting damage based on the user's Venus power and the target's Venus resistance. The attack may also inflict Delusion on the target. Evil Eye visually resembles the user attacking the target and a bright orange cloud emitting on impact.

The weapon, of course, is not likely to be useful to the party for a very long period of time, as the Great Western Sea is opened up shortly after Gaia Rock. It's unleash, while by no means underpowered, has the rather underwhelming side-effect of delusion rather than a more useful one such as sleep or a statistical debuff. Also, although it can be equipped by Felix to take advantage of the weapon's Venus alignment, there are many Long Sword class weapons that outperform it before and after Gaia Rock. Therefore, it would be more effective to save the coins that would otherwise be spent having Sunshine forge it.
