My experience is that my character priest (with high oratory skill) is lord of region that has 13300 peasants.
He build level 5 temple in the region that can provide for ca. 17500 followers.
He also build 5 shrines to the religion.
He managed to reach 11000 believers in 3-4 months preaching and after that he is daily preaching for last several months with no change - what he get by preaching he lose after the turn change.
Also, considering shrines - I have noticed that regions with shrines that are drawing gold from the global treasury are rapidly losing followers regardless of there is huge amount of gold in the global treasury.
Thank you for information that shrines are used for converting nearby regions.
From the description I was under impression that their main use is to replace temples in regions where temple can not be built.
Still, it would be nice to see upgrade to the game that will grant to local lord to build in his region temple to any existing religion instead to his religion only.
