Having it down to a skill roll takes away a feeling of either earned consequence or achievement. You didn't do anything. You just rolled a good number. It's empty. The Githyanki encounter where you need to persuade Lae'zel to play along is a well implemented skill roll. But this one just feels arbitrary. And the only thing that's going to happen is me reloading the conversation because it's not my choices that get the kid killed it's a die roll, so I'm just not going to accept it. And I doubt I'm the only one that feels this way.
