I want to know if the levels of parents must be exactly 10, 15 or 20, or simply the minimum level required?? I managed to get the plankton dragon (with 2 dragons level 10 and no more), but I can not have other unique dragons, dragons are my levels may be too high (15 to 25). Someone managed to get a dragon with higher levels?

Thanks
