Lucky Box was a monthly event in which players could obtain exclusive epic skins. The event began in 2016 with Miya "Christmas Cheer" (now "Christmas Carnival") and continued until June 2020 during Chang'e "Lunar Magic". The event has remain in silence for while since the introduction of Epic Showcase, which was later replaced by Grand Collection. The event returned in random occasions to resell the newly revamped skins that came from it.
Draws
The event has about 14 prizes, and the user can exclude four non-ultimate prizes from the draw. The first draw is free, and then cost 90 Crystal of Aurora for the second draw.
