so how do you determine if ropes are properly tied in the first place? is it DM fiat?Properly tied ropes are inescapable without help, so no roll allowed (you only roll if the result is in doubt). If the PC has access to something like a knife or a rough surface the question becomes whether or not they can cut the rope and free their hands without dropping the knife or a guard noticing. Either skill could be applicable depending upon the situation - SoH, for example, to keep the knife or the half-cut-through rope hidden from the guard.
