Spawn Chesterson’s as much as you want!
Whenever you are struggling to get the coins for the next hero maybe try out this.
A quick and effective way to get alot of coins is to make use of the “Fight/Leave Boss” button. Everytime you leave a boss fight a random monster will spawn. We make use of this game mechanic and simply click “Join/Leave” over and over until we get a Chesterson spawn.
