In this video I completed the post game Farewell Mecha grunty Quest. You will note that I avoid the optional battles during this quest, resulting in a lower grade. At this point in the game items were plentiful and i decided to just skip those to get at the meat of the quest. I give mecha grunty and his minions a pretty good licking, resulting in some of the quickest battles I have had since the beginning of the game.
