Pandora's box increases all campaign rewards for the campaigns it participates by 3% for every 5000 growth (increase of the total gain). This caps at 100k growth. Reaching the cap will increase it to 4% every 5k. This increases by 0.1% for every feeding, for up to 2% additional (resets to 0% after rebirthing or if hunger reaches 0).				Increase the bonus for all campaigns by an extra 0.9% * class level if your class is an adventurer.

Note

Cannot use a Pet Token to bypass evolve bonus condition.

Pandora's Box's special ability multiplies the overall campaign result, i.e. the total of all pets' contributions. This makes it easily the best campaign pet, due to both its versatility and power. Pandora's Box should not be used in the same campaign as the Mimic, or else its bonus will be turned into a penalty.

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))%.

There is a Challenge Points purchase that prevents Pandora from losing its feeding bonus when it reaches 0 fullness; however, even with this purchase, its feeding bonus still resets when you rebirth.
