This combination is a pretty standard martial/ spellcasting mix. It needs two ability scores: either Strength or Dexterity for the weapon usage and Charisma for spellcasting. This puts it on par with a “half caster” like the herald or wielder classes in terms of ability usage. Which ability gets the strongest focus is largely a choice between emphasizing weapons combat or spellcasting. Flavor-wise, this combination works as well as any martial + magical combination; both classes have a bit of a “blank slate” element to them, which means that the archetypes do even more to define the character than usual. A stronger focus on fighter levels gives you a warrior with a few key spells. Top picks will probably include standbys like shield, magic missile, grease, web, and mirror image that provide straightforward combat or battlefield control benefits. More levels of sorcerer gives you a spellcaster that can hold their own in weapons combat and wear armor. An even mix of the two gives you the classing fighting spellcaster who can flow freely between weapons use and spellcasting as the situation dictates.
