Simple Q&A Pathfinder (By RAW) I

[Arbane]

For whatever it's worth, though, a piece of design advice I got a long time ago was: If you require a check, assume they'll fail. If what's behind the statue (in this case) is required to complete the adventure, then maybe you want to rethink your method; if, on the other hand, what's there is just bonus stuff (extra loot, a shortcut to the end, etc), then definitely require some sort of check to earn the bonus.

Good advice, this. Don't have players roll dice unless you can deal with them failing or succeeding.

And specifically for situations like this one, don't forget the Take 20 rules.
