They don't both have to have red/yellow but both colours must be there. You can breed fire/air or two different red/yellow hybrids. I don't like to add any other colours to the mix tho as then there are even more possible outcome.
Agreed! I bred fire and air and got mythic on the second attempt. Am now up to five plus mil. And counting to afford the habitat so I can get this fool out of my GD nest. Glad I saved up toget a second nest a while ago, comes in handy.
