This might be a moot point, but I wanted to see if this made sense to anyone else. The talent itself talks about allowing an Investigator to "Take 20" on a knowledge check even if in immediate danger or distracted, if they spend an inspiration.
The question is, what about the time issue with "Take 20"? When you take 20, you take 20 times the normal to make the check. Thus the average standard action takes 2 minutes.
I get the impression that the talent is intended to allow a take 20 in combat, as a standard action but it doesn't say so explicitly. Any thoughts?
FYI, the talent is on page 20 of the Advanced Class pdf, and you can read up about Take-20 here
