The Dark God (暗黒神 Ankokushin, also translated as Evil God) is an enemy-only combat class that is exclusive to Fire Emblem Gaiden. The personal class of Duma, one of the sibling gods overseeing the continent of Valentia and the final boss of Gaiden, the Dark God class resembles a swamp monster and attacks with tentacles and beams from its eyeballs. Attacks performed by the class with the Eyebeam and Eyeball are considered to be magical.
It should be noted that the Dark 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.
