And this is where magic COULD be overwhelmingly powerful if the magic is treated with some sort of force behind it like a sword stroke and assuming if they keep getting hit while coming towards you or while flying Mage seems like the perfect choice and a sword Mage even better.
At a distance you could spam spells with "force" damage to keep hitting it back if it responds to the magic like a sword. And in cc hit it with the sword. If done right it might meen that a Dragon or any other creature would be unable to vey close to you jmo.
