Advantages of Mages over other races.

As Major Vortex already mentioned, these effects can be removed by a weak hero. I think there’s a different problem here. To make the mini-arts effective, you should gain as much knowledge as possible, which results in mages having around 400 mana, while 200 mana is usually more than enough for a battle. This leaves 200 extra mana, but instead, I would like to increase combat characteristics.
