Taking Aurica's path to avoid an evil boss in Misha's.

Am I insane? Probably, but I've been thinking about this for a while now.
Problems/list of stuff:
-Lag. Ohhhh the lag.
-When to Dive, who to Dive into, how far to go? (Probably Aurica, though Misha has a mandatory Lv1)
-What items to get/make? Definitely Peeka (RC Pig), but what about attack or healing items?
-If/when to levelgrind?
-How possible IS a low level game, because a speedrun is that, just with the added "bonus" of having to rush through everywhere. Usually with LLGs you still get all the items, so you're equipped fine, but low level...
-Lots of other things that I can't remember right now.

Wish me luck?
