Pet Soul Stones are used to evolve Pets to a new star ranking. But Pet Soul Stones are probably the rarest ones in the game and can only be obtained through Pet Summoning or opening enough Pets Soul Stone Chest. Once you get an absolute star Pet you can trade-in additional Pet Soul Stones for Pet Soul Coins in the Pet Soul Stone Shop.
