What is there to know about the Chests?

You will receive at chest a the end of each fight won.

There are different types of Chests given the fight won.

Only one chest can be opened at a time. Each Chests have a timer.

When opening a Chest, you will have to wait until the timer runs out to get what is inside. However using in-game currencies will allow you to get the content without waiting.

The rarer the Chest is the longer the timer will be.

You can own a maximum of 6 Chests. If you already have 6 Chests that you haven't opened yet and go for a fight, you will not obtain any new Chests, so don't forget to open them!
