Indy spell casting levels

[QXel]

Hello everybody,

I have a stupid and academic question: at which level the Indies spellcasters cast spells?

I explain a little better: for a player (either IA or human), his spellcasters can only cast known spells, depending on what research levels he has reach in each school of magic.

But what about the Indies spellcasters?

A good question, indeed ...

P.S.: I don't have searched in the forum, cause the search function is not very easy and clever in its working.
P.P.S.: the purpose of this question is for projects in modding maps, so maybe this good place will be in the modding forum? But I know that lots of really good Dom3 engineers lay around

Thanks in advance.
