The bonuses from the Academy of Mages don't look very advantageous compared to the bonuses from Ormond, which grants access to the same skills. Ormond's only drawbacks are a slight penalty to useless strength and a small penalty to stamina (but overall, it's still better and easily compensates for this penalty), while it has the most of everything else, including mana. Bardilar, at least, has access to all four elements and, potentially, higher magic power.

Well, here it's a matter of quest-based freedom. Almost anyone can pay to join the Academy and become a mage (they charge foreigners much more, but they still let them in; the problem is that there aren't many who want to). I'll probably level them up eventually, but only after magic becomes a strong build in general.

I really want money, but it's so hard to implement the Turan-aristocratic background with the intended idea...

It's not easy for me either to explain to the commoners that I'm implementing a hybrid elite build with swordsmanship, armor, a shield, and a special ability for sabers. I have to spend event points on useless tasks instead of getting meta special abilities and parrying buffs.

Am I right in understanding that all types of magic, except for necromancy, can be freely practiced in almost any region?

Mm, no. First, no one likes any mages except for elementalists. Elementalists are treated more or less normally because their powers are visible, and they won't control your mind or secretly curse you. Ardor doesn't like mages at all, and those who practice magic there either have to give it up forever or leave immediately. There are no second chances.
In the rest of the world, all mages, even necromancers, are tolerated as long as they don't cause trouble. From the point of view of the main religions, magic is considered a sin, but lying and stealing are also considered sins, and no one sets out to commit a holy genocide of thieves... until they try to steal from their own wallets. And the forbidden fruit is sweet, so people are drawn to these kinds of miracles. Well, sometimes wizards, as they say, "cause trouble," but since an ordinary mage can't even handle the righteous anger of a dozen peasants, they either do it secretly or under the protection and in the interests of those in power. Or they are very powerful mages for whom everything is easy, but when those in power take them seriously, they rarely live long.
