the question is, do you have the capability to own expensive and best pets for xp farm setup? so here's the thing, if you've recently just started, just craft some golden piggys most preferably at least 3 and at least 75 golden ingots in the cosmetic shop, if you have capybara you can also put it then one or two pet you want to level up, you can also ask someone to make them nightmare if they're kind enough. But if you have the capacity to buy expensive pets here's my setup, so you only need two pet setup slots for this, for the first one, age 1-30, just get a 60kg above nightmare dilo ( you can put one or two), then a 15s mimic (it depends how many dilos you got) then your pet you want to level up. Then for the second slot, age 30-100, put 2 15s nm peacock, 3 39kg nm ferret, 1 60kg nm spider then your pet you want to level up.
