I only used it in automatic mode. It gave four classes of items, A through D. D were potions and crap while A were much rarer and desirable. So you could leave it running all day in the PC version while you did other things and end up with a ton of rare items with zero effort or work. People say the junction system was broken but chocobo world took it to another level. a ton of items to mod into magic or w/e just as soon as your GFs learn the appropriate abilities.
