Heleg, find the Settings button; you can select the Russian language there. The idea of each faction having only one type of magic is good. But then you will have to make the schools similar and universal; otherwise, it will create an imbalance. That is, each school should have an attack spell, an area-of-effect spell, a powerful area-of-effect spell, the most powerful single-target spell, a set of buffs and curses, and something related to mana... It is better to make sets with diverse magic. As an option, you can study the main school completely, and the other three non-main schools without third (fifth) level spells. Ranmaru Rei, I would still give demons fire magic.
