If you deal too much damage to the King, he casts his ultimate attack, which deals damage proportionate to the number of chibi mogs left alive at the time. The intended strategy is to kill as many of them as possible as quickly as possible, because the move is also on a timer. Generally, they are killed in order based on their overall danger to the party. A group of gung-hos spamming AoEs on all of them right as the King spawns can trigger his ultimate, or if all the DPS are going after the King, that will trigger it too.
