I tamed a griffin on mobile when I was only level 40! My friend said that you can only get a griffin when you are level 80 and up! I could not believe that I had a griffin but he had a fight with a carbonemy and lived! He had only 2 health left so I feed him 2 pieces of meat and 14 pieces of mejoberry and then we went for a walk and...he found my old pet just standing there by a rock and they became friends. the end
Before you all go naming your griffins "Buckbeak" lemme lay some mythology on ya. Buckbeak from Harry Potter was actually a hippogriff which is a horse combined with a eagle. A griffin is a lion combined with an eagle. Just keep this in mind before going on a Buckbeak naming spree.
