A colorful stone suddenly appeared in Igor's hand, and he gradually transformed the stone.
Back then, when he was tinkering with the stone with Hustace, they just infused it with lightning, not realizing that the stone would undergo such a drastic change. Ordinary stone, due to lightning, turned into Rain Crystal Stones. Igor did not understand the stone's value at the time and made a lot of them in one go... Later, when he went to Guru Mountain, this imitation stone caused quite a stir, most importantly showing that the stone could also become a means of attack.
After successfully transforming an imitation Rain Crystal Stone, Igor gradually began to transform another Rain Crystal Stone, now contemplating using these Rain Crystal Stones to make a big impact.
Once this stone is destroyed, it can release powerful thunder, a secret known only to Igor.
