Quick tip for those that are having issues completing the specific "have x people pepped and combo this rare monster" quests:
When you get your 5th person and can switch out members of the party, pep doesn't go away for the character switched out. So if someone is a pain to get pepped (serena) just swap her out for another character for a few battles until the other folks get pepped. Once they both are, flee the battle or win quick so you don't lose it, swap her back in, then evac/zoom from wherever you are to the location you need to drop the ability. That spitzfire quest gives you some fur crafting items that basically require you to be in the next area anyway to really take advantage of, unless you are farming the shit out of spitzfires and stealing a lot.
Game is A+ DQ. Loving it so far in basically every aspect hah.
