The Thunder Mage (サンダーマージ Sandā māji) is a combat magical class that is introduced in Fire Emblem: Genealogy of the Holy War. This class is one of three split branches of the original Mage class, solely wielding Thunder Magic as its weapon of choice.

History in the SeriesEdit

In its original inception in Genealogy of the Holy War, the Thunder Mage class is a variant of the classic Mage class that specializes in Thunder Magic. This version of the class promotes into the Mage Fighter class.

The splitting of the Mage class is not repeated again until Radiant Dawn, replaced instead by the Fire, Thunder and Wind variants. This version of the Thunder Mage (雷魔道士サンダーマージ Sandā māji) class promotes into the Thunder Sage class, and can further promote into the Archsage class when the necessary requirements are met.



In Genealogy of the Holy War, as a trade-off for their lack of versatility, Thunder Mages can use B-rank Thunder Magic (ignoring holy blood bonuses) instead of the usual C-rank limit for generalist Mages.
