Advanced mode?

Is there any difference in items between doing Expert X-1 and X-10 or 15? I dont see any (IE. Volcano expert -1 vs Volcano expert 10) does 10 give better skills or $$ or items or any difference?)

Nope!
You can rest assured knowing that there is no difference in the prizes.
The drop rate percentage is the same for all the maps of a region. This is the same for the types of prizes.

Good luck!
