Whats the difference between the mystical and enhanced.
what I see or think is that they do the same thing but the price is different.

the colors are more acurate with the mystical essence, they have the same amount of trait but when you generate a pet you get a color swing on it that may change some color. If you make a project you may want to be sure that you get the good colors on your generated pet mostly the white and the black (those tend to get bad color swing)
