Priest

The Priest (プリースト Purīsuto) is a support magical class that recurrently appears across the Fire Emblem Series, beginning from Shadow Dragon and the Blade of Light. Mainly intended for support purposes, Priests are only capable of aiding allies with the power of staves. As such, Priests are unable to directly attack, save for Radiant Dawn, where they are bequeathed the ability to counterattack.

History in the Series
In its original inception in Shadow Dragon and the Blade of Light, the Curate (そうりょ Sōryo, lit. Monk) is a unisex class and can eventually promote into Bishops.

In Gaiden, the Priest class is female-exclusive and can also wield Swords and Black Magic on top of healing with White Magic. The promoted form of female Mages, this class doubles as the base class of Celica, who is further able to promote into the Princess class.

In Mystery of the Emblem, the Priest class is removed from the series temporarily, replaced by the female-only Sister class.

The Priest (プリースト Purīsuto) class returns in Genealogy of the Holy War and Thracia 776, where the class is again unisex and promotes into the High Priest class.

In TearRing Saga: Utna Heroes Saga, the Priest class is unable to promote.

Beginning from Binding Blade, the Priest class is reinstated into the series with the Bishop class acting as its staple promoted form. As Bishops, Priests are granted the ability to arm Light Magic for combat purposes.

In The Sacred Stones, the Priest class is separated from the Cleric class and is rendered almost exclusively male-only from most of the future games in the series. It is also further given the option to promote into the Sage class alongside the Bishop class. As Sages, Priests can also access Anima Magic alongside Light Magic.

In Radiant Dawn, the Priest ( 神官プリースト Purīsuto) class is again made unisex, with Laura acting as the only playable character of this class. The Priest class promotes into the Bishop class in this title, much like its predecessors.

In Shadow Dragon, the Priest class is known as the Curate (僧侶 Sōryo lit. Monk) and Wrys is re-introduced to the series.

In Awakening, while Priests cannot promote into Bishops, they are instead given the option to promote either into War Monks or Sages.

In Fates, the Priest class is called Monk (修験者 Shugenja) and is regarded as a Hoshidan class. Considered the male counterpart of the Shrine Maiden class, Monks are given the option to promote either into Great Masters or Onmyoji.

Combat
Priests serve the sole purpose of aiding their allies through their healing staves, replenishing their HP when they sustain damage during combat. Locked to using their healing staves as their primary source of experience gains (aside from the paltry amounts they get from being engaged in combat by hostile units), the player thus has no other option but to ensure that their ability is utilised as much as is possible until they reach a level appropriate for promotion. As they also happen to be physically frail due to their low Defense, Priests must always be deployed alongside bodyguards to shield them from onslaughts while they work in the sidelines to support their allies.
