The Fell God (邪神, Jashin lit. Evil God in the Japanese Version) is an enemy-only combat class that is exclusive to Fire Emblem Gaiden and its remake, Fire Emblem Echoes: Shadows of Valentia. The personal class of Duma, one of the sibling gods overseeing the continent of Valentia and the final boss of Gaiden and Echoes, the Fell God class resembles a swamp monster and attacks with tentacles and beams from its eyeballs. Attacks performed by the class with Ocular Beam and Oculus are considered to be magical.
It should be noted that the Fell God class cannot be defeated without the use of the Falchion wielded by Alm. It will not sustain damage past 52 HP with ordinary weapons, save for Nosferatu.
Due to the way the game is coded, the Fell God class shares similar properties with the Fighter and Hero classes.
If the class is hacked onto a playable character, they will have multiple Black Magic tomes. However, they cannot be used since the only weapon the class can use when at 52 HP or under is Oculus, which is inaccessible on any character other than Duma.
