The Valor Pass is a purchasable offer which grants you Premium Rewards on top of the Free Rewards. It is valid for 50 days which is the duration of the Path of Valor Event.
When Challenges are completed, Valor Points are rewarded. Accumulating Valor Points lets you reach Path of Valor Milestones and unlock fantastic Rewards!
When the Path of Valor is closed, there will be a break between each Path of Valor Event, depending on the month. During the break, it is not possible to buy the Valor Pass, nor to gather Valor Points.
