You make a reasonable point about shared XP.<br/><br/>I did consider individual XP and also participatory shared XP, though came to the conclusion that, given peoples' vastly different schedules and availability, it will be far more equitable to take a one in / all in approach. However, note that I am treating items in a very different way and that chance will favor those who have put forward their case. ;)<br/><br/>Since we have the most observant party in the history of the game, with multiple best-possible-outcome rolls for Perception, I might as well post the next scene...
