So I did some testing I thought that Spirit and Vitality gave Mana Regen and LP Regen respectively.
But I can confirm that Magic is the one that scales the Mana Regen not Spirit.
As for Vitality I couldn't create a reliable test to test it out.
I really have no idea what Vitality does.
The farther you progress the harder it is to tell. I capped all my research so who know what is a stat bonus or research
I also found out that you can disable the Cultural Developments when selecting the Difficulty of the Map(at the bottom).
So at least that is taken out of the eqaution when testing things out.
