The Genpeerstone (Japanese: 同性有利の竜石Same Sex Advantage Dragon Stone) is a Stone that debuted in Fire Emblem Warriors, appearing exclusively via its paid downloadable content. The Genpeerstone is a stone which comes with a built-in attribute that boosts damage output against an opponent of the same gender as the wielder--simply put, a male wielder deals more damage against a male target, and likewise a female wielder deals more damage against a female target--but lowers damage output against an opposite-gender opponent.
