The biggest difference between humans and beasts is that humans create and use arcane implements to arm themselves.
Before the Era of Beast Control, a Trainer who could defeat a beast of the same rank solely relying on their personal strength was considered an exceptional existence.
However, in this era, a Trainer fully armed with high-level arcane implements, even without a pet to protect themselves, can still defeat or even slaughter several beasts of the same strength.
Similarly, if a pet is equipped with armed arcane implements, the pet's innate physical strength and casting abilities can be further enhanced by the weapons crafted by human blacksmiths, maximizing its power.
However, because the destructive or defensive power of a pet will be significantly increased after using pet arms, it's very easy for the pet to die in battle if not handled properly.
