well, I'm just in the save before a boss, and I already buy the "increase Sp" and "increase item drop" blessings, along with some other stuff, like "increase hp recovery" and the "improved armor".
I have 50k of Sp, and i'm not sure what it is the best to buy now. I did some tests, and the "less mp usage" and the "faster skill recovery" don't improve so much (at least in the first lvl upgrade).
so... what is the best thing to buy?
Also, the SP carries over to a new game (if I play yunica again, on another difficulty, for example)?
sorry for any bad english.
