Thank you. :) Basically, the whole point of my suggestion is to randomize the situation, rather than outcome--which is still firmly in the hands of the player. If the player fails because he/she is not up to the challenge, they are more likely to accept it as part of their story and if they don't accept it and decide to load the saved game, after all, they will not be as frustrated because it's not the game or the RNG that's making them fail, it's them. Of course, you shouldn't force players into situations that their characters cannot handle yet but you likewise shouldn't bar them from trying it on their own: if they do beat it, they'll feel amazing about themselves; if they fail, they'll learn a valuable lesson about jumping the gun. :D
