Stamina

Stamina is the attribute that allows a character to sustain themselves while maintaining physically stressing actions. As stamina is hard to categorize, like for example how much time you can fight before getting exhausted and the amount of time you can run before getting exhausted will be different, and as such categorizations aren't fitting, so instead just describe their stamina, for example: Naruto fought constantly for multiple days on end, however just describing their stamina as High, Low, Average, Endless, etc, is also fine.

Infinite stamina should only be granted if characters can use their abilities any amount of times without exhausting.
