Chests

Treasure chests are generated after 25 successful victories after the end of a battle. The chance that such a chest will appear is 25%.
At the end of a fight, a random colored chest (chest) can be generated that can only be opened with the appropriate key (key).
But act quickly because the chest only stays active for 45 seconds after which it despawns. There is also a chance that such a chest is a mimic and initiates a fight. Each color of the chest has its own item pool.
