I do not not know if this subject was in this topic (but it is to much to read, and my translator is bad). It is about rebuild mage guild. I think it is a good ideea to rebuild just one spell, but I also think that is bad to spend lot of resources and learn nothing, at least if opponent it is more lucky to obtain faster what he seek at least let the other to learn what he payed anyway. In fewer words I think it normal to pay for something not to pay for nothing.
