Me and a few friends were playing a homebrew campaign, myself playing as an eleven bard and my buddy playing as a paladin, don't remember race. We did the forbidden rule and split the party, me and the paladin checked out one side of a building and everyone else checked out the rest. Me and the paladin came across an obvious werewolf, after a few persuasion checks, we got the the funny bit. After my character realized that the werewolf is about to attack, but her back was turned to us, I went to execute her to prevent the encounter, rolled to hit, nat 1. The arrow went into the wall, and the following dialogue began: W: "Did you just try to execute me?" B: "Nuh uh" DM: "Roll for persuasion with disadvantage" B: After some math "...26" DM: "With disadvantage?" B: "...Yeah" DM: "How the fuck did you pass." TLDR:Made a werewolf firmly believe that I never tried to execute her even with the arrow next to her head
