Stamina

Stamina is an in-game item that is used to play levels in the game. Normal Campaign levels require 6 stamina points to play, and Elite Campaign requires 12 stamina. The normal way to gain stamina is by waiting, as you gain one stamina point for every six minutes you wait. Every time you level up your team level, you get a bunch of free stamina at once, and the ability to carry a little bit more stamina. If you get too much free stamina, the bar can go over its limit, but it will not make stamina on its own until you empty it below the limit. Stamina can also be gained by playing the game at certain hours of the day to get a free 60 stamina. One last way to gain stamina is by buying it, to buy stamina will cost 50 gems, but it will give you 120 stamina. You can only buy stamina once per day if you're not a VIP, however.
