Some cannon-like objects were placed at the end of the arena. Those were magic items that could shoot small targets into the sky at a certain interval. For the record, Alesia also made them for the Royal Academy's Annual Tournament.
After ten cannons were placed in place, the host began to announce the start of the long-range division and called 24 students at once. Unlike the short-range, it wasn't in a battle royale format and was more of a score battle and would take longer time.
10 cannons and 24 students, 4 from each academy in a batch; those who got the most targets after a certain time would win.
The format of the tournament was worse than the short-range tournament because if there were at least 2 skilled opponents in one place, they would have a lower chance of advancing to the final.
