CREO STARS-
Creo stars tell you how good your Creo are. If your Creo have 1 star,but are a high level, you have probably wasted your time. The more stars, the better, and, based on how high the stars are when you do Creo summons, It is sometimes worthwhile to do it, as the stars can be 7 or higher. Creo stars are not to be confused with loyalty, as that can be seen when you look at the Creo profile(When I did the summon, I got a 7 star Crywtolo! Not a total rip-off!)
