Hello!!!

I'm thinking of reverse breeding a lioness in my pride, her name is Mau and she is generation 4 or 5? (Idrk how the generations work) Noctis Heavy Rosette at 100%, and all 6 markings are breed only, breed only base, eyes, mane type and mane color. The only problem is she's infernal and so someone would have to buy the Chasteberry in the snake quests.

I don't know how to price her or how reverse breeding works so could anyone help me and give me some tips? Only if you want to and thank you so much!
