Aurelius Valerianus Illyovich:
Boss question...
Obviously if you take an Alt-Rank later in the game that changes your salary class it changes your salary accordingly. That's pretty obvious. The question is what if you take one are Rank 1 since it's all base character creation?
Ex...say I'm a Noble and take the Redemptionist Rank 1 alt. Clerics normally are Ministorum Class that gives them 200 thrones a month. Redmptionist changes that to Supine Class giving them 70 thrones a month but Noble Wealth says you are a Nobility Class that gets 500 thrones a month.
The latest change over-rides earlier ones. In your example the character would have a base of Ecclesiarchy, have that changed by Noble, then have it changed again by Redemptionist. He/she would have given up her House stipend in order to show piety.
