Pandora's Box

Note
Cannot use a Pet Token to bypass evolve bonus condition.

Pandora is easily the best campaign pet, due to both its versatility and power. While it can be unlocked by killing P.Baal v66, it is a good option for an early-game token unlock. Its power scales as it gains growth, capping at 100k. Feeding Pandora will add to its base % multiplier. For example, having 100k and 0 feeds, all campaign gains are increased by 80% (100k/5k*4)%. With 20 feeds (60 hours needed), this increases to 120% (100k/5k*(4+2))%.

Pandora's Box should not be used in the same campaign as the Mimic, or else its bonus will be turned into a penalty.
