I'm making some progress, and moving as stealthilly as possible. If one or two of you would be willing to mount up in case I need help fast, I'd apreciate it, but unless they are specifically trained observers, I should be able to observe them without being observed in return.
ooc: DC 23 and 25 means even on a natural 20, they'd have to have ranks in spot and listen or a Wisdom of at least 16 to succeed. Always good to have a contingency plan though...
