Reserve Rank
The Reserve Rank is your Creature Reserves level. Ranking up your Creature Reserve will grant rewards.
To increase your Reserve Rank you’ll need Creature Reserve XP which is granted based on how happy your Creatures are. You can also earn one time bonus XP from adopting Creatures and completing Creature Sidequests. Creature Reserve XP is granted once a week via the in-game mailbox.
Reserve Rating
Your Reserve Rating is based on the total happiness of your Creatures that week. The happier your Creatures are, the higher your rating will be.
There are four total ratings that your Reserve can have: No Rating, Bronze, Silver, and Gold. Your Rating will affect how much of the weekly reward you receive.
Your Reserve Rating will be adjusted once a week when you collect your weekly Creature Reserve XP.
