Players will be rewarded with the Loot Box by using their stamina in playing the game. Without the stamina, players can still play the game as usual but only a small reward will be given.
Stamina will be refreshed daily, and each player will have different stamina depending on the number of heroes or skins in their possession. A stamina system will be used to control the supply.
