...having a high level persona (instead of low level) could increases your random points on social links.
For example, I fused a Kikuri-hime with the expense of me blowing most of my money on compendium to 1) beat the Rise/Teddie shadow(s) and 2) boost social link. Then, I started following the guide, until I realized some prompts were just skipped (I think it was 5-6 or 6-7 where either TV reporter comes in or the lady from the inn comes in and the last prompt was skipped) and, next thing I knew, I was one level higher than the guide (I think it was level 7, instead of 6 or something) I spent the extra hour on fishing (Yeah, not a wise decision in the retrospect)
I am sure I was following the guide to the T (or G, idk), but I can't explain how I was a level higher, other than I was using high level persona for Priestess arcana for other social links. (Thanks to that (probably), my Strength arcana took a huge hit. It's November, and it's still rank 8).
Can anyone confirm this?
