Priests

[OmikronWarrior]

I believe there are two and only two ways of increasing priest levels.

1) Make a priest a prophet. You can only do this to one unit (which actually doesn't have to be a priest), and it will become a level 3 priest, or a level 4 priest if it already was a level 3 priest.

2) There exists one or two artifacts (const-8) that will raise a priest's level by 1.

For the most part, you're stuck with the priests you're given.
