This is exactly what I did. Sarasvati with almost all the elements (had her with Hama), was pretty fantastic. Though right now, I've just completed
and now I'm looking to move onto the next great Persona to build up to. What would it be, I wonder? *looks around*
I've fully maxed out my SL with Yukiko, got the trophies for it, and noticed that the last part is fully voice acted. I don't remember if this was the same as the original PS2 version, but I found it to be pretty cool. Trying to max out Chie and Rise as fast as I can, then I'll focus on Nanako and Dojima next. I'm on 7/20, in case people are wondering.
Also, I stumbled upon the pub that opens where the item shop is in the Evening. Is there any value to trading weapons with her? Seems like Daidara gets a lot of the good stuff.
