You're only supposed to open the spoiler and read the 'hidden information' if you beat or equal perception 20. So you roll the D20 (or use a dice-rolling app, site, whatever), and add your 'perception' skill value and that's the result. You can also 'take ten' or 'take twenty' - see the top of the previous post for how this works. If there is something tasty inside the spoiler, I'll probably suggest you read it anyway but to keep in mind that it is still 'hidden information' as far as your character is concerned. Anyway this is all somehow 'optional' - do whatever gives you the most enjoyment so long as it doesn't spoil the other's enjoyment of the game. Probably answered in too much detail, but others may have a similar question so it can be good to have the complete answer.}
