Reins Of Unity may be used on Calyrex to fuse with a Glastrier or Spectrier in your party. If you have both in your party, it will fuse the one in the firstmost slot.
The crafting incredient items White Mane Hair and Black Mane Hair are obtained upon capturing either Glastrier or Spectrier. Radiant Petal may be crafted by collecting petals, which you may learn more about on its page.
