The pets give a buff which if you want to level and dont have ap to buy potions and stuff, then you can use the pet buffs. But i have the pets only to level, when i get bored. Yea, figured I like the pet defense and offense buffs better then leveling. But do not waste your gold, unless you just want to have something to fool around with, if anything. LC pets are like my cat. Does not do anything, but nice to have, lol.
