Question on how you would have handled something:
I had a door in a dungeon with a series of gemstones next to it like a keypad. One of the characters decided to try to pry one out of the wall to take it, and was thrown backwards, knife left stuck partially behind the stone.
The cleric decides to smack the knife with his shovel (his holy symbol) to knock it free. I can’t decide if I want this to rip the gem from the wall or let the knife go free, so I think a Defy Danger roll would work well, but I can’t figure out an attribute to roll. In the end, I had him roll + nothing (suggesting it was a “luck” roll).
What would you have done?
