Grievous Mace

A Grievous Mace (Gravity Mace in Japan) is a Mace found in Golden Sun. It is one of the prizes that can be won in the Lucky Medal Fountain in Tolbi. It can be bought for 7000 coins and sold for 5250 coins. Being a Mace, it can be equipped by Isaac, Felix, Garet, Sheba, Mia, and Piers. It increases the wielder's attack by 88, and inflicts Venus damage rather than physical.

A Grievous Mace's Unleash attack is Terra Strike (Earth Attack in Japan). Terra Strike attacks with an additional 20 attack points. Visually, Terra Strike resembles a normal attack with a stalagmite rising out of the ground to strike the target. In Dark Dawn, it has an additional unleash: Fearless Attack. It is found in the Cancer Zodiac room within Craggy Peak Ruins.

Like Assassin Blades, weapons stronger than Grievous Maces don't appear until Lunpa (aside from Assassin Blades themselves). This is the only weapon from the spring that Mia can wield, so if one is won it will most likely be given to her. However, being a purely Venus-based offensive measure, Isaac himself would be a viable candidate because the weapon will do enhanced damage based on his Venus power rating, and is especially strong against monsters with low Venus resistance ratings, namely the Gargoyle and Tornado Lizard monster lines.
