"fes" is the abbreviation of "festival", which means festival in translation. It belongs to the limited card pool category in this game.
This FES card pool cannot be redeemed through recruitment points if it is not UP, and overall it tests the player's luck;
Although the probability of an up being drawn is only a fixed 0.7%, it is still easier to draw incorrectly than a normal up. There is also a probability that the same character will be drawn when drawing (duplicate characters will be automatically converted into character fragments and universal fragments);
During the server opening period, the probability of three stars in the card pool will double, which is about 6%. It is recommended to redeem the recruitment points obtained by drawing 200 points for up characters in a single period.
