Dragon Quest VI: Realms of Revelation/Area level caps

In this game are "Area level caps", which determine which areas you can and cannot class grind in at certain levels. For example, if you are using a party of Level 24 characters, you will never get any class experience at Weaver's Peak(Dream World). You can fight a 1000 battles there, and still remain a 1 Star Warrior by the end of it. However, if you are using a party of Level 5 people (or Level 15 in the Android version), you can grind there until someone levels up to 6 or 16. When that happens, said person will stop gaining class experience there.
