Well, if trying and failing the deception check could then lead to her escaping without giving you any reward if you then failed a subsequent melee check, rather than simply being able to choose one of the other options as I think happens currently, then I agree that would mitigate my concern. I’m not sure that I prefer it to the current set of possible outcomes, but I’m not sure that I don’t either! It would partly come down to the difficulty of the melee check.
Wait, if you fail the deception check then you can simply choose one of the other options? That's it? No penalty for trying to be greedy and deceive the hag??
