Spirit Potion

Spirit Potions were items used to gain level ups for Cookies and Pets without needing to obtain specific copies of them. Each Spirit Potion counted as one copy of an Epic, seven copies of a Rare, and thirty copies of a Common. Spirit Potions couldn't be used to upgrade Legendary or Special Cookies and Pets, but Special Spirit Potions, an Event-exclusive yellow variant, could have been used to obtain copies of a Special Cookie or Pet. Spirit Potions could only be used on Cookies and Pets that have been unlocked and found.

Obtaining Spirit Potions
Spirit Potions were obtained primarily from Cookie Trials and Trophy Race. During a New Cookie Cup in Cookie Trials, more Spirit Potions were available from Trial Goals, and after the New Cookie Cup concludes, all players who reached Diamond would have received Spirit Potions based on their relative score. In later Lands of Trophy Race, Gold Chests were guaranteed to contain one Spirit Potion each, along with other valuables. This adds up over time, since it is good practice to be regularly opening Gold Chests.

Spirit Potions were also obtained from Events and crafted in the Magic Laboratory. If a great surplus of Magic Powder is stored up, it could have been converted into Blue Bottles and Solid Blue Sugar Crystals to create Spirit Potions, but note they could have only been crafted every three days.

Special Spirit Potions were only obtained from Events, and only rarely.

Using Spirit Potions
Spirit Potions were spent from the detail menu pages for the Cookie or Pet they were intended to be used on. Following complaints from players who accidentally used a large amount of Potions on a single Cookie, there was a confirmation message if the player wanted to use all the owned Spirit Potions on one Cookie or Pet.

Spirit Potions were best spent on Epic Cookies and Pets. Rare units were regularly received from all forms of Cookie Chest or Pet Egg, and Common units were not especially valuable. Cookies and Pets included in currently active New Cookie Cups were a good investment for Spirit Potions, as reaching Diamond will help the player earn more Spirit Potions back. Cookies and Pets that scored well in Trophy Race were also a wise investment, but units currently available in Guild Runs and Champions League can be worth upgrading, and any Epic units that the player wishes to upgrade are not a bad choice.
