Necromancer

The Necromancer is a class exclusive to Prince Lyon in Fire Emblem:The Sacred Stones, who is given his power by the Dark Stone of Grado. The class itself serves as a unique third tier equivalent of the Summoner class due to it's ablity to summon Phantoms. The Necromancer is considered one of the most powerful magical classes in Fire Emblem:The Sacred Stones, and is possibly the most powerful dark magic user. In addition, Lyon possess the abillity to use staves, like most magic users, making him a very versitile character. However, he can only be unlocked by beating the Lagdou Ruins three times after the game is complete, making Necromancers one of the hardest classes to obtain, if not the hardest. However, if the feat is managed, he'll make a welcome addition to any team. The phantoms by a necromancer are higher in luck and generally stronger than that of a summoner's phantom.

It is a common misconception that Lyon/the Necromancer class could use all four magic types (light, anima, dark and staves) in the Japanese version of the game. This rumour is false, and originated because Lyon is seen casting thunder in the game's opening class roll (it is unknown why he casts this spell, because in the game he can't, possibly a miscoding in the game ).

If you use a cheat code and change a character who is not Lyon into a Necromancer, they will be unable to summon.
