WyvrnBlade"Camellia"

A cool blade that heats you to the core. Beauty and violence all in one sword.
When a hunter puts their spirit into the softly glowing blade, it changes completely. The blade quickly heats up, shining as if aflame and giving off heat. Its power rises in step with the state of mind of the hunter who holds it, making it the finest of fine swords.
