One thing I've seen occasional reference to is prepared casters using various Divination spells to help them figure out what challenges they might face on the following day, thus allowing them to prepare spells as appropriate. However, details of how they go about doing this are almost always non-existent. So, my questions are:
1.) What spells do you use to do this, and which generally aren't that useful, and why?
2.) What questions do you ask when using said spells?
Of course, I'd imagine that it all depends heavily on context, so allow me to throw out some basic context to attempt to shape the advice to what'll be the most widely useful:
- Your character knows that he or she will be going on some sort of adventure tomorrow, but for whatever reason, has no details of what that adventure might be or what it might involve.
- Your character will be travelling as part a well-rounded and generally competent party. Thus, traps and locks can likely be left to the party's rogue-analogue, etc.
