I just started trying this last night (after it took 2 hours in the Omega Ruins to get No Encounter equipment for someone). I got to 46 in a row, but then I guess I would doze off and get struck. I guess that's what happens when playing at 2am. :P

I've already got Yuna's and Rikku's weapons powered up, Lulu's will probably be next. Then maybe Tidus. Auron's seems kinda hard to get, Kimahri and the butterflies is just insane, and blitzball? Oy my team sucks. >_<
