Priest

Priests are a kind of agent in Hyrule: Total War.

Acquisition
A Priest costs 500 rupees and requires at least a Temple of their associated religion to recruit. All Goddess Worship and Majora Worship factions can recruit priests, as well as the Order of the Wizzrobe.

Function
The main stat of a Priest unit is Piety, which increases their religious conversion effect and their chance to denounce heretics/witches. A Priest will convert the surrounding region to their faction's religion, which will increase public order if the faction in control shares the same religion and increase unrest it if they do not.

When the percentage of the population in a settlement worshiping their home faction's religion reaches certain thresholds, said settlement will also be able to build better and better religious buildings of said faith, which further increase the rate of conversion and give other bonuses.

As Goddess Priestesses and Disciples of Majora spread their faith, they increase the likelihood of the Oacca and Church of Majora emergent factions spawning.

The Order of the Wizzrobe fields unique priests known as Bishops, who are vital to Wizzrobe expansion. Bishops function identically to Priests in that they spread the Wizzrobes' faith- "Wizzrobe Influence." As Wizzrobe Influence increases in a city from the Bishop offering his services and ideals to townsfolk, its unrest dramatically increases as they grow to like the Wizzrobes rather than their own government. Naturally when this unrest reaches a boiling point (around 75% Wizzrobe Influence), the city will rebel... allowing the Wizzrobes to move in and take it without having to declare war. This naturally makes the Wizzrobe Bishop the most important unit in a Wizzrobe force early on in the game. Players will want to train as many of them from your Cathedral as possible and send them to key territories they'll want down the road. This method has the added benefit of working against every faction with the exception of the Gohma and Stalfos, allowing the Wizzrobes to spread out into areas of the campaign map early on rather than cluster themselves near the Hylian descended factions.
