In the original Japanese release, this is the first version of the Exhibition Finale, which was regarded as too difficult for most players to complete. This encounter was later changed to a less difficult nerfed version.
Note you CANNOT use the revive full party option (using 3 Command Seals or 1 Saint Quartz) in this quest! If your party falls, the quest immediately ends.
