Joint Firing Drill

Joint Firing Drill or Joint Firepower Exercise (JE) is a game mode otherwise known as a time attack dungeon. The goal is to clear stages in the shortest time period possible to earn the highest score.

Joint Firing Drill works fairly similar to the Raid game mode. 3 tickets are given daily and once one run is completed, the remaining tickets can be used to sweep. There are 4 different stages to select from with the latter increasing in difficulty. Students can be borrowed from circles with the same conditions as those in raids. However, it is important to note that failing to complete a stage will not prevent the students used from participating again.

To begin, enter the current exercise being held. The exercise is started by pressing the yellow button on the bottom right of the screen. The blue button to the left can be used to start a mock exercise. Once started, 3 stages need to be cleared with 3 separate teams. Each team will earn a score based on the time used to complete the stage and the stage's difficulty. After 3 stages are cleared, each team's score will be aggregated into a final score and provide rewards based on the tiers below. Joint Firing Drill coins can be spent in the Shop.
