After reading https://royals.ms/forum/threads/a-guide-to-donations.72652/ It was noted that "Donator Pets and mounts [Note: Attack boosting skills from correspoding donator pets are disabled]" So I was wondering if donator pet is kinda at disadvantage compare to normal pet? Donator pet have no evolution? What is closeness for?
Donor pets have no advantages over NX pets. Some pet commands require a certain level of closeness, that's about it. The only evolving pets are baby dragon and robo.
