Cold and solid scales from a Solitary Suanni. They retain pure adeptal energy even after falling off and cannot be damaged by ordinary weapons.
Ordinary beasts can sometimes be affected by errant adeptal energy and become more powerful than usual. However, a suanni's adeptal energy originates from within themselves, which is why their leader is often regarded as equal to adepti.
Despite being considered auspicious beasts, there are nearly-forgotten legends of a suanni named "the mountain lord" attacking villages. The Wushou Dance was thought to have originated from a ritual to appease said being. However, since very few people have seen a suanni at all, the theory naturally cannot be verified.
