Colosseum/Duels
Stamina
Players can participate in the Colosseum and Duels by spending 1 Stamina and can get points as rewards for spending Stamina.
For Duels, Stamina can be expended only three times during their 1-hour-long run time, meaning points can be earned a maximum of 12 times per day.
The Colosseum differs from Duels in that it is always open, but players can only receive points a maximum of three times per day.
*It is possible to make an attempt with no Stamina, and have your score change.
