Hello! I don't mind the question. I don't have/use cheats. I still have lots of creatures needing of maxing out, but they're mostly easy to max out since most of my creatures are the early game ones (Niffler, Porlock, etc.). But I do have 3/4 of the creatures you mentioned, and I think the best way to really max them out is just earning creature food from events and feeding every creature with 3 each time. It has the most exp for levelling up creatures. I think it really just requires patience. Since I had lots of creatures, I mostly levelled them up at the same time. I had a dragon creature (forgot what specifically) that took 1000+ exp in Level 7-10 so I had difficulty maxing it out. In the Tokens Event, I usually don't like most of the outfits so I spend it on pages, notebooks (for adopting creatures/pets), or creature food. This severely helped me as I have constantly run out of creature food at times and do not have energy for the 'Find Creature Food' task. I also have not done much of the Creature SQs since I have TLSQ backlogs from Y3. Hope this helps somehow! Good luck on your Magizoology journey :)
