Temples and Priests

[Silius Saurus]

I was wondering at what levels of temple construction the priest ancillaries start showing up.

According to the triggers at the bottom of export descr ancillaries:

Spoiler Alert, click show to read: 

Trigger trigger_priest_of_Apollo
WhenToTest CharacterTurnEnd
Condition EndedInSettlement
and RemainingMPPercentage = 100
and SettlementBuildingExists >= GROWTH_HEALTH_temple
and SettlementBuildingExists >= wine1
and SettlementBuildingExists >= baths
and Trait PublicFaith > 0
and CultureType roman
and IsGeneral
and Attribute Electability < 1

AcquireAncillary priest_of_Apollo chance 15

Judging from the fact that they all say either GROWTH_HEALTH_temple, GROWTH_TRADE_temple, etc, and not something like GROWTH_HEALTH_shrine, large temple or awesome temple, I'm going to guess that it starts at temple level(2nd level).
