Excellent graphics and storyline. The game has the worst 5 star summon rates. A F2P player can get a max of 50 to 80 gems a day and every summon costs 200 gems. In order to get a 5 star hero 85 summons are needed so in total 17000 gems. Except for some limited time events the game becomes far monotonous in the long run. 1 energy refill requires 10 mins and you need atleast 10 energy for each battle hence even farming for resources is too time consuming.
