“Heroes of Might and Magic V: Tribes of the East”

Hello everyone, could you please help me? Suggest a map where I can play 1v1, and where there's a "mentor" and an astrology tower. I really want to try out these new features. Also, another question: Does Ossir immediately get the "Luck" perk and have "Magic Resistance" learned? To unlock the super perk "True Luck" in the Luck specialization, do I need to upgrade something other than "Magic Resistance"? It seems like Ossir can't achieve the "True Luck" perk. I would really appreciate your help!

And where can I get the "Stopping Cold" spell?
