OMG, thanks a lot for your reply, it means a lot for me!
It's an interesting thing you mentioned Savyna and Lyude, because I don't use them on RTA. Savyna not at all, and Lyude only for a short time when a 3rd character is required. I know it can be surprising that I don't use Savyna, but there are some reasons for that. First, her items for upgrading classes are not convenient to get. Second, her decks are not that good for straights etc. And third, I am not very good with her. That's why I don't use her. However, I need to consider her for the TAS, for obvious reasons (she attacks really fast).
Same thing for Mizuti, I don't think I will any use of her. Xelha being mandatory at some point, I better focus on her. And her Classes up are WAY easier. But that will require further investigations, of course.
It's also a good thing that you talk about the segmented run. I didn't think about posting it there, but you did. Because yes I referred to the SDA segmented run, that can itself be improved. Thanks for that. I would also like to post
my own RTA PB/WR and
my own notes/route for that if anyone wants them for comparison.
Besides, I didn't mention it, but I still don't really know which version I should use between NTSC-U and -J versions, The texts are not important in this game and textboxes display instantly if I want them to. And in fights, I just watch the number that correspond to the attack or the defense, the kind of item it is, and the color for the element. However, I will probably menu a lot, so maybe -U is more convenient. Unless some big JP only glitch is found, because this game is still glitchless sadly. The JP version was released over a year before the US version after all, so there was plenty of time to fix things, if there were any.
