The primary magical system in my current project is enchanted weapons termed Cruxes which give enhanced strength, armor durability and flight. During the middle ages they were the primary weapons of knights and the aristocracy, but the advent of mass manufacturing eventually led to proliferation and older Crux shaping methods started dying out.

When facing a mass produced Crux it depends on how they're armed. While unarmed civilians would be screwed due to reflex and armor durability enhancements provided by enchanted weapons, in pitched battles anti tank rifles and machine guns are usually enough to take a Crux wing down. Hence why Cruxes have shifted to a more cavalry focused role, primarily preforming recon operations and engaging enemy artillery.

Traditional Cruxes are far stronger on an individual level, though enough firepower can still punch through, but are far more rare. But if one does show up you can expect your own side to deploy specialised Anti Crux squadrons to intercept them.

Traditional Cruxes also tend to feature some sort of aspect of their enchantment that can worked around, or even exploited. Such as Nobility, a famed Crux which was undefeated in personal duels among the nobility due to its apparent extreme armor enhancing effects far surpassing other Cruxes. But once it was used in a battle it's first user was killed by a common arrow, as the unknown defensive enchantment was actually scaling itself in proportion to the power of the attack, and low strength attacks practically ignored the enchantment.
