Water Jacket

The Water Jacket (Aqua Jacket in Japan) is a Clothing-class piece of equipment found in Golden Sun. It is found in a treasure chest in the bottom-left room of Hammet Palace. As Clothing-class equipment, it can be equipped by all Adepts.

The Water Jacket increases the wearer's defense by 30. Also, it increases the wearer's Mars resistance by 20 and Mercury resistance by 30. It can be bought for 3000 coins and sold for 2250 coins.

The Water Jacket is a valuable piece of equipment not only because it protects from physical attacks but since it also reduces damage from elemental attacks (albeit only two of the four elements). This is especially valuable considering the Mercury-based monsters that attack while crossing the Karagol Sea. The Storm Gear found in Crossbone Isle can be considered a vastly upgraded version of the Water Jacket, even capable of defending against Jupiter-based attacks. Another such upgrade exists in the Dragon Scales, though to a lesser extent and without the Jupiter resistance. Other alternatives include the Spirit Armor found in Tolbi and the Dragon Mail and Dragon Robe in Golden Sun: The Lost Age, although none of these offer as strong of an elemental resistance as the Water Jacket. The Spirit Armor is notable, however, in that it defends from all four elements rather than just two.
