I don't think that RAW comments on how loud a failed lock pick attempt is versus a successful one. I think that's more in the "rulings not rules" category, which seems perfectly suited to his kind of situation.
Right. The DM would have to homebrew in one being louder than the other. It's not RAW that it is. If you feel the need to make a failed attempt louder for some reason(and I see no reason why it should be), then you can do so.
Why do you think the timing matters in this way? And what's the difference between someone else who makes those rolls in the moment as needed in play?
This is why I think this quantum label is kind of useless... it's fiction that we're talking about. At one point, it doesn't exist, and then a moment later it does.
It matters if you want the world to feel like it exists independently of the players. "Quantum" for the DM doesn't affect that feeling, since he is running the world and setting things like this up in response to player driven play.
If the roll is done in the moment by the DM, it takes a little bit away from the world being independent of the players, since the roll is happening right then because of the players, rather than having been done prior and the encounter already existing within the world.
If the roll is done in the moment by the players, it takes away a huge amount of the world being independent of the players, since the encounter is relying on a player roll.
No, you came up with the farrier in response to the player bringing up the farrier, and then you treated the farrier as if he was there all along.
It was there all along, since towns pretty much always have farriers. I just didn't think to write it down before then.
No, not if the attempt to get through the door is what brings them to the room or otherwise alerts them.
It would alert them with a successful roll as well, though. Poking around with tools trying to gently turn tumblers isn't going to be louder for someone without skill as with. At least not significantly so. You're making it sound like the unskilled person is just pounding the tools into the lock and making a bunch of noise.
I'm actually looking at the 5e rules and there's no such thing as picking a lock without skill. You must be proficient with thieves' tools to even pick a lock, so this entire argument is moot. It's skilled vs. skilled. One just may have a higher bonus is all.
Again, rulings not rules. One GM may rule as you do above. Another may decide that a lock pick attempt includes all the relevant factors of attempting to pick a lock, including being aware of potential observers and making noise. That seems reasonable since typically most GMs aren't going to ask for 5 different rolls for one action.
Again, this is homebrew and not RAW. Homebrew has no real place in a discussion about rules. By RAW, picking locks picks the lock. There's nothing additional to it.
Now, I personally don't really mind if people want to use "quantum" as a criticism because I feel I can address that. But when a poster is calling for others to stop using words they don't like, the fact that they use words others don't like seems relevant. I'd much rather we all stop complaining about what words are used and instead talk about the ideas that words convey.
It's not even a criticism, since we are applying the term to both sides of this discussion.
