But I am not "triggering combat". I am talking to some guy and the designer thought no matter what this will end in a fight of either 6 against 4 or 7 against 3.
This is a single guy in a cave, not a giant skeleton with a burning skull that everyone told you is a tyrant. Why would I assume there is combat soon?? Try to see it from a new players point of view. You talk to someone and suddenly completely out of the blue you're in a fight you can not win. Why did the designers think that's a great idea?
