In Kingdom Hearts 358/2 Days, enemy attacks may be classed under one of thirteen elements, each associated with one of the members of Organization XIII. These elements do not represent the type of damage dealt; rather, they determine the status effects that may be inflicted. This sometimes results in odd combinations, such as the Neoshadow being able to use a Flower-type attack.
List of Elements
Light (光, Hikari?) is the signature element of Roxas and Xion, and it is the element associated with Sora, Donald, Goofy, and the King. Light-based attacks can zap the target's radar, disabling their map.
Many ring panels provide the wearer with resistance against one or more elements, reducing the chance of receiving the corresponding status effect or effects.
Additionally, each member of Organization XIII has a natural resistance to their respective element, which increases as they level up. Similarly, Xion, Sora, Donald, Goofy and the King have natural resistance to Light.
