How do I levels pets to 80?

So can i upgrade 75s I have besides finding others?

I’m trying to score any 10* eggs by farming but I’ve found absolutely nothing.

@Cult Yes. As explained before, if you have a low rarity egg at level 75 and find a higher rarity egg of the same pet, instead of just feeding that egg through synthesis, you go to the pet counter at shopping plaza and use pet rarity enhancement. That way you get your level 75 pet to a higher rarity, saving you the pain of having to re-level.

@Cult rarity 10 onward is pretty rare to drop and only drops in certain quests, however most eggs are in the collection folder so you can get then from there too however the element they come is just bad
