[Skyblade]

I usually start stockpiling on limit breaks once I leave Midgar in Disc 1, and continue it each time I get another character in my party. That's basically my early preparation for the stolen materia sidequest.

I start stockpiling Limit Breaks in Midgar. Cloud has Blade Beam by the first boss, and there's something satisfying about unleashing Meteorain against Rufus.

I found this area as well. When I first played VII, it was a friend's copy, and for a week or so I couldn't get the second disc from him, so I spent the time exploring and trying out various areas.
