Yeah, he isn't only going to be a fire mage. He just wants the title back.
Besides having the knowledge for the magics, he also has monopoly over the appraisal magic/tech which is what deposed him in the first place. He can hold onto that title easier this time around too. So the only challenge now would be surpassing his predecessor.
I'm not sure if he would aim to be an all-rounder. He still seems to have a preference to fire magic. Though if I were to guess his next step after the title, it would probably be maxing out his Spirit which was his best stat iirc. The only thing holding him back on that part is money.
