Yes, I know. The DM shut it down. My suggestion was about what could have been… another way to handle it. In that imagined scenario, the DM would not simply shut things down, but nor would they just grant the player the entirety of their request. They’d work with the player to see if they could find a way to get the idea to work.
Then I suggested some ways to do that. My suggestions were based on a very brief description of the situation, with a lot of relevant details missing. As more details were provided, I attempted to incorporate those into my suggestions.
So the end result is not a perfect example. But it’s the idea that matters.
