Ultimate Magic

Ultimate Magic (究極魔法) is a secret magic technique of the Elf Tribe.

Description
This magic technique is capable of producing incredibly powerful spells.

Despite being a secret technique of the elves, it can be taught to humans.

Trivia

 * In the official English translation, Yami Sukehiro mentions that some mages learned to use "ultimate magic" by exploring dungeons. However, Yami uses the term saikyō no mahō (最強の魔法), which is different from the one later used for the elves' magic technique.
