Stamina or Energy is required to enter Challenges, Campaign battles, and Resource missions. Arena battles consume Pips instead, Story and Operations do not have a cost to enter, and Raids are only limited to 3 per day and characters cannot be reused in the same day. Stamina is tied to the account, and is shared across all characters.

* For challenge battles stamina is only consumed in case of victory. In case of defeat it is not used up.

The same amount is consumed regardless of the number of characters on the team. Stamina regenerates slowly, at 1 per 10 minutes. There are 2 dailies that award Stamina - 60 for logging in, 30 for participating in 3 Arena battles, meaning that every day you can at least gain 234 Stamina. Stamina can also be obtained randomly from coin chests, including the one that you can obtain free every three hours.

There is a "soft" cap on Stamina depending on player level (60 at level 1, increasing by 1 per level); more Stamina can be earned and kept through Objectives, but Stamina will only naturally generate if under the cap.

Gaining a level awards bonus Stamina.

2-10 30
11-20 40
21-30 50
31-40 60

51-60 80

Stamina can be refilled for 50 Power Gems for up to 10 times a day.

If you win a campaign battle, you will be awarded account XP equal to the stamina spent.
