Heroes of Might and Magic V [Game Discussion]

Thank you. It worked. And how do you level up your Mage?

Mages... Well, I don't play as them very often. Usually, I improve all the skills related to artifacts (master of artifacts, artifact absorption, etc.) and level up machines (power over machines, ballista control). I do all this through the skill tree, but I don't know the Mage skill tree very well.
