I've saved my NX and bought the dragon egg and rock of evolution from the cash shop. I followed this post: https://royals.ms/forum/threads/evolving-pets-clarification.11300/ But when I go to Ria she only says "Hello" to me... she doesn't mention a quest to evolve my dragon egg. PLEASE HELP Invested a lot of NX to get the black dragon..
That thread follows the Old Source method of getting an adult dragon. Now I believe you level up the baby Dragon to Lv. 15 or something, and then it evolves on it's own to a random color. 0:
Oh no! What if I don't like the color then? I have to keep buying the evolution stone and redoing the quest items?
This is an excellent guide: https://royals.ms/forum/threads/everything-about-pets.62615/ As you can read for yourself, you can change the colour an unlimited amount of time for the cost of a Rock of Evolution.
