5 carts of Lyn stones
Sato closed his eyes, a look of deep concentration etched onto his features. He kept his hands in front of him, ensuring that his grip on the Lyn stone remained steady.
As he began to channel his magic into the stone, it began to emit a bright green light that illuminated the room.
In Sato's mind, a flurry of images and ideas coalesced into a single, clear vision. With unwavering focus, Sato directed his magic towards the formation of this object.
The Lyn stone seemed to split into threads of pulsating energy, swirling and coiling in mid-air before taking on a tangible form.
With a flourish, Sato opened his eyes and revealed what he had created. The threads of energy had coalesced into a beautiful black rifle gun, gleaming with the same green light as the Lyn stone.
Sato smiled with satisfaction, his magic once again proving to be a powerful tool in his arsenal.
