In my opinion, it’s better to complement the schools of magic. For example, Nature doesn’t have direct damage spells, but Chaos does. Nature + Chaos = a decent number of blessings, i.e., you can manage without Life (although it has excellent blessings). But there will be few curses, so you can learn a little bit of Death magic. For a mage, Combat skill is enough among non-magical skills, although Bob lived without it too :). On the contrary, magic is not necessary for a warrior; instead, they should mainly develop combat skills, but you also need to think about what to develop and what can wait.
