Water Jacket

The Water Jacket is a Clothing-class piece of equipment found in.

The Water Jacket is a valuable piece of equipment not only because it protects from physical attacks, but because 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.
