Keys

Keys are necessary items needed to open chests. The amount of keys needed to open chests depends on the rarity of the chest. The number of keys you have is between where it shows your burgle points as well as your gold on the top of your screen.

How to obtain

 * From Missions.
 * Buying with Friend points
 * From User rank rewards
 * From waiting 10 minutes per key (Max 10 keys)

Trivia

 * Keys have a small chance to open chests immediately. This chance can be increased by buying the Locksmith Training miracle from the Cat God Shrine.
 * Keys acquired from Missions, purchases, or rewards will stack over the limit of 10, but you won't get any more from waiting if you have 10 or more keys.
