spells that you would never want.

[Temotei]

It is mostly that vague part that bothers me. The rest, especially the casting time if you don't happen to have the thing at hand, is just annoying. Also, it "often" directs you to more detailed information--not always. This is probably a plus from a DM perspective (keep some important part of history obscured so the entire plot they've devised isn't spoiled or whatever), but overall I just don't like the spell. Power-wise it's okay sometimes.
