Shamans used rituals just as the immortals and others used arts. One of the biggest differences between rituals and arts was that a ritual only had to be performed once, and the shaman would forever be granted the corresponding ability. Kai Syaoran had carried out the Sightless Ritual, and this permanently gave him the ability to create illusions using his eyes. This ability would forever be with him since the sacrifice keys that made it possible were carved into his soul when he carried out the ritual. The ability would grow in power as Kai Syaoran's cultivation increased. For shaman rituals, there was no limit to the power that the abilities they granted could unleash. As long as the shaman grew more powerful, their abilities would grow in power as well, with no limit having ever been found.
