Question about variable effects/cost for spells
 

Hi all

a question about varaiable effects/cost for spells:

1) Fatigue: it is clear that the fatigue cost of a spells is affected by the level of the castere in that way:

fatigue cost = fatigue cost / (caster level - required level +1)

2) Range: (es. 30+) how level affects range ?
3) Number of effects: (es 4+) how level affeccts number of effects ?
4) Area: (es 7+) how level affects area ?

is there a common rule (with some/a lot of) exception or every spell behave in a different way ? if the second option is the true I really hope someone (Zen ???) soon could be able to release a detailed spell guide

good play
