@Da_Gut I feel like the biggest pitfall in this (and lots of other roleplaying, so not just this) is that players often conflate what they do (their action) with the outcome/result, usually in such a way that assumes success, even if success is unsure or even impossible. Then the GM either has to deal with the assumed success, or conflict with the player by negating what they said, or figuring out how to walk it back or rephrase it, potentially making the player feel like they've lost agency.
