"You got a 13, you miss."
A phrase often heard at the gaming table: a sad and uninspiring statement that renders the PC's actions and efforts meaningless; It shuts them down; and takes them out of the game.
The idea that I had was to let them describe their failed attack in terms of the encounter (or challenge) allowing them some narrative control.
The next time a PC misses I am going to ask them: "Describe what happened?"; "Tell me about the attack that missed" or "Tell us what went wrong".
Just a short thought for the day.
