I came by this RMS item while looking at MiyabiDoll card.
Miyabi Ningyo Egg: [monster egg] An egg that has Cute-pet Miyabi Ningyo sleeping in it. Can be hatched by using a Pet Incubator.
INT + 1, Reduce Casting Time by 3%.
Is it possible for our pets to be coded to give some sort of buffs (ie. stats, +atk, +maxHP, +SPrecovery, ) when they're out of their eggs? Or get bonuses just by having those eggs in the inventory list?
