Haven't any of you gained a level after a dialog? Minor spoiler - like the fisherman tricked into digging out the Mind Flayer. Obviously, you get XP (and some weirdly underpowered gear) if you kill them, but you also get XP if you send them away without killing them. I have not paid attention to the amount, but you can get from level 1 to level 3 just doing a lot of exploring and dialogs with very little fighting. So this thread seems weird like I could see discussing the amount of XP, but it seems to imply there isn't any which is untrue.
