Less flashy than Fire, but its efficiency, power, and range are top-tier. However, it is said that no one can currently wield it. Ice: Magic derived from Water. It freezes water to increase power. Not many can wield it. Star: Magic derived from Water, Fire, Lightning, Wind, and Light. Milesia is the only user. Nature: Magic derived from Earth and Wind. It utilizes the environment; while its offense and defense are top-tier, its strength varies depending on the surroundings. Healing: Magic applied from Water, Wind, Light, and Nature. Unusable in combat, it focuses primarily on treatment. It is highly valued due to the scarcity of users. Snow: Magic derived from Water and Ice.
