All magic is weaker than Noctis’s and you get one offensive spell which can change based on skills equipped (either weapon or a king skill). You heal, which can change base on king skills (in one case forgoing healing for a buff) And you get a block button, same deal. That’s you’re magic.
Oh I also fought Noctis’s buddies, Ignis was the easiest, like a blind man without a cane. Promptos was the most frustrating but not threatening. Gladios got parried and died.
