Faith bonus
An altar can generate an area of influence and it is possible for the influence from the altars of different gods to overlap. One will be dominant and when you enter its area you are told you feel the influence of the appropriate god.
This influence can be visible when you look at spell effects, you will sometimes see a faith bonus which is generated from the influence. The amounts vary (possibly on distance from the altar and its quality) but normally you can expect the bonus to reach a maximum power of 55. You will only get this high a bonus when your god's influence is dominant in the location you are in.
Once your faith passes 90 the additional faith counts towards your faith bonus. This means a 92.20 faith priest could see a bonus as high as 57.20 (55.0 + (92.20 - 90))
Faith bonus affects the success of your spells so it is a case of the higher the better.
