Aside from the intense training, Kain also had another crucial aspect he needed to pay attention to in terms of strength improvement, and after several weeks of waiting, the Kain finally presented itself to him in the System's store.
After becoming a 3-star beast-tamer, although extraordinary equipment for their level, both the armor and spear were no longer as useful to improving Kain's strength.
Before the second re-ranking, Kain had already upgraded his armor and spear for ones at the 3-star level by exchanging his school credits. However, despite the high quality of the equipment provided by the school, they couldn't at all compare to the custom spear provided by the System that Kain got accustomed to. Even his armor, while not provided by the System, had been shaped using Bea's spiritual power and was in a way a piece of custom equipment.
