No, I said there may be. It'd be awesome if someone actually offered an example from play that would display it, rather than resorting to hypotheticals. But it seems no one can because the people who are more likely to shut it down don't even acknowledge the rules in the first place.
I realize you'll ignore the nuance in that, and instead place me back in the "always allowed" bucket, while simultaneously saying I've erroneously placed you in the "never ever" bucket, but that's where we're at. It's why I said "neener neener" in my last post to you... it seems we're past the point of having a reasonable discussion on this.
So does not allowing it to work. The request for an audience doesn't sound like the most meaningful scene to roleplay out. But you know what likely would be? The actual audience. All the ability does is allow for the opportunity.
Plus, that can be said of any action taken. If the DM is not obliged to allow anything to happen... if he gets to pick and choose what may or may not happen, and which rules to honor or not... or which to interpret in such a way as to shut things down... then roleplaying may not be necessary for a variety of scenes.
How many other player side abilities do you deny in this way? Are players beholden to permission to cast a spell?
Well, it goes back to trusting the players. People always talk about the need to trust the DM... but we need to trust the players, too. If it's been established that there's no inn in town, then no one should say "I go to the inn". Otherwise, who cares? Let there be an inn. What's that going to harm? Especially since whatever advantage the inn may offer is still something that the DM has huge say over.
Okay, you go to the inn. Sorry, there are no rooms. Sorry, there are no rumors. Sorry, there are no hirelings. Sorry, move along.
All these examples seem so petty, don't they? They're clearly about preserving the DM's predetermined details even if those details don't make a whit of difference.
