The side quests seem to require a lot of careful planning and prior knowledge to do in any kind of efficient way. You have to know to get Asselio his x5 Steel Lances before fighting Slayde for the last time, you only have access to so many peddlers, there's always the threat of reinforcement spawning...and sometimes, you even have to farm a few items.
So, let's say you were speed running this game; doing some sort of "100%" category, or whatever. What would be the best path? Far as I can tell (and this is assuming you're getting the relevant items from all places you visit)...
So, what do you guys think?
