[P5V12+] About Rozemyne's Magic

Do we ever learn about whether or not there is something special about Rozemyne or if it's just her belief in the gods being much stronger than the (current) people in Yurgenschmidt? There is some teasing that happens in Part 3 with the Goddess' Bath and things like that, but as far as I remember, it's later described that people COULD do the same things that Rozemyne does if they had the same mana capacity and truly believed in the gods.
