Soothing

Bright (うるおい), renamed Shining (光かがやく) in Kingdom Hearts 358/2 Days, is a material type available in Kingdom Hearts, Kingdom Hearts II, and Kingdom Hearts 358/2 Days. Bright materials contain the essence of vitality, and are colored green. In Kingdom Hearts and Kingdom Hearts 358/2 Days they are used as normal synthesis items, while in Kingdom Hearts II they are "modifier" materials that can be added to a recipe of the same rank to double the experience that it will give to the Moogle, and are usable once the Moogle reaches level 2, Novice Moogle. In Kingdom Hearts II, once all Bright materials are obtained the Moogle will reward Sora with a Defense Boost.
