I'm currently on a 2nd play-through, and it just occurred to me that some aspects of the game, mostly on the battle system, aren't explained. For instance, was it ever explained what the 'letters' (P, S, R) on the special skills denote? The so-called "secret methods".
I only learned of their effects through the use of a guide here in GameFAQs, but I'm assuming I would *never* know their purpose if I had not bothered looking for them on the internet. At least as far as I can recall, they were left untouched until the end, and players aren't given an in-depth description of it [secret methods].
Anyone care to shed some light on this issue? 'Cause I find that these little details, when not explained to players, has a tendency to leave a void in the overall knowledge about the game. And it's not exactly pleasant, either. I mean, you get to finish the game without even knowing or utilizing a certain feature. :\
