Okay, This game is too good to be broken in this way. My party is as follows:
Oliver lv 36
Esther lv 35
Swaine lv 33
I've just gotten to the inevitable point in any JRPG when things just get way fucking harder for what seems like no reason. I'm used to it. The thing about Ni No Kuni is the world is huge and nonlinear in a lot of great ways. And one very bad way. My current objective is to get the three stones for Oliver's flashy new wand. The first two stones were laughable in their difficulty to obtain.
But now I'm on the third one, the one in the Glittering Grotto. When I started dying frequently I figured that last place the story brought me to (Autumnia) would be the best place to grind. But the creatures all run away from me and when I do get a chance to fight them they hardly do anything for me EXP wise. The creatures of Autumnia are two weak and the ones near and in the Glittering Grotto are ridiculously strong. There's got to be some middle ground but I don't know where.
TL;DR- Where can a mid 30 to low 40 lv party go to grind in this game?
