As with most f2p games, there is app story purchases. But this game is one of the more greedier games there is. The cost for diamonds and the amount needed to actually do anything with them is high. I dont mind putting 5 bucks here or there, but in this game 5 bucks gets u, almost nothing.
The good news is its not needed. Most of the arena fights are pve type of contests so u dont get whooped in 1 hit and hate trying again. The costs are high, probably to entice cashers to spend but u can easily have tons of fun without. With the event and heroic dungeon rotations, u always feel like u can up grade. But if u plan to be close to the top then plan to spend more than u ever have had to.
All in all, its a pretty good dungeon crawler that ull come back to time and time again.
