Theory and Practice

I don't quite understand this point... Guildmaster is purely a combat class! That is, he doesn't have any magic initially. So, isn't there a risk that if you level up a particular magical school enough, the Guildmaster class will change into something like a Fire Diviner? Please clarify the situation...

Hmm... we level up Nobility and Scouting as the main skills - and make sure that the number of skills in the Chaos magic being leveled up doesn't exceed the number of skills in either Nobility or Scouting: I wrote in the previous post - to get, for example, a Guildmaster with expert magic (6 skills), you need Nobility and Scouting to be at least 7 (or even 6?) skills, then the class
won't change ;)
