For the character of the same name bearing this class, seeRhea.

The Immaculate One (Japanese:白きものThe white one) is amonsterclass which debuted inFire Emblem: Three Houses. It is used exclusively byRhea in her appearances as the final boss of the Silver Snow and Crimson Flower routes. It represents her true form as a dragon of legend, who was revered in history books held by theChurch of Seiros's library.

Though the Immaculate One lacks proper programmed stats, it is exceptionally strong all around. It boasts four largehealth bars, highstrength andmagic, very highluck andcharm, and a mix of offensive and defensiveabilities that make it even more difficult to take down. In particular, its combination of a strongbarrier andAncient Dragonskin give it incredibly tough endurance overall despite having lower rawdefense orresistance.

There are three variants of the Immaculate One present within the game's code. Two are used for Rhea's appearance in the Silver Snow campaign; a weaker variant with lower stats, and a stronger variant with higher stats and the abilitySurging Light, which allows it to use itsStaggering Blow without preparing it beforehand. Both variants have a wide variety of abilities both offensive and defensive. The Crimson Flower variant is somewhat more tuned towards raw power and one-on-one combat, with abilities such asAncient Dragon Wrath, which allows it to hit the lower of its target's defenses, as well asGiant Wings andWrath. Being a monster class, however, all variants of the Immaculate One share similar weaknesses that other monsters do, including slightly below-averagespeed and the possibility of anarmor break.
