During the event, for every 20 Energy consumed in "Campaign" or "Outpost" (including Joint Battle) modes, 1 reward-doubling chance is automatically consumed, granting 1 extra "Campaign" or "Outpost" reward. For every 60 Energy consumed in "Sword Trial" mode, 3 reward-doubling chances are automatically consumed, granting 1 extra "Sword Trial" reward.
30 reward-doubling chances are refreshed every Friday at 5:00:00. Unused chances can be carried over to the next week, up to a maximum of 60 during the event.
