DO NOT PLAY THIS GAME. Games like this should be illegal considering they are pay to win but also do not keep the RNG and difficulty constant. What I mean by that is you can increase the levels of your heros and damage of your arrows but the game will compensate and make the enemies harder. The game recognizes what things you'd need to get from chest roles and will not give you them in hopes you'll pay for more chest roles. I've been at level 237 for 2 weeks playing daily...avoid this game
