My point is yes you can intimidate someone without breaking the law or creating a situation where it breaks the game if you fail. Your earlier example on intimidation and your idea of intimidation as a thing is very narrow and that is why you can't see the possibilities.
Regarding the dracolich, you can kill him eaily. You can not automatically intimidate him into helping you and in the example I used "intimidation" worked for a while until said dracolich developed a plan to get it back (a bold plan I might add that suceeded) so in the end the cleric "failed" his intimidation check and the dracolich did not stay in line.
The examples I gave are exactly that - examples. You need to be creative in your game and develop examples based on your situation, but I can say in my games intimidation is used more than almost any other social skill and it is almost NEVER "I will beat you up if you don't do this". Physical domination against the one being intimidated is rarely part of intimidation in the games I play. I also think it is going to be MORE difficult to "persuade" a Vampire or warlord to do something he does not want to do then it will be to "intimidate" him. How are you going to persuade the old king, or warlord or anyone to do something they don't want? I could come up with silly follow on answers to any examples you could use as well, and this is key come up with something that works for the situation your player is in and generate the conditions if it is not readily apparent.
I will also note I did not say put the vampire into a magic circle, I said draw one and convince him (deception) that it is a teleport circle and that pushing him into it will teleport and kill him (intimidation).
Intimidate has nothing to do with being strong or weak, it has to do with finding a leverage point against the NPC you are trying to intimidate. Said NPC could be much, much stronger than you and it can still be successful.
As far as employees - many, many bosses tell employees they have to work certain hours or holidays or follow rules they don't want to follow with the implict threat that they will lose their job if they don't. If a manager tells a server at Denny's restaurant - "you need to wear a mask or go home" that is intimidation and it is happening literally thousands of times today.
Again, though, that vampire can't be intimidated unless you deceive them first. And If I have the time to draw a circle, and the skill to decieve them... why do I even need the intimidation? I've already convinced them that I am one move away from killing them.
It seems like you see Intimidation as "sealing the deal", like, having the power to kill someone or convincing you to kill you can kill them isn't enough. You also have to succeed an intimidation check. But, in most of the games I've been in, if you already have that much power over a person, you just succeed.
Exactly. In one situation, only persuasion works. In another, only intimidation works. In another, both can work equally. In another, one is easier than the other. It doesn't seem inbalanced, then.
Except the "situation" is that the DM is fiating and deciding that a skill won't work before you go to roll. If the DM doesn't decide that the Guard cannot possibly be persuaded, then persuasion is still an option.
And if both are an option, persuasion is the better choice.
Sure, there's been failed democracies as well. I'm not saying that it's perfect, but it's a pretty stable form of government within the ruler's lifetime, which is what matters to you.
Intimidation is something mean to do. You don't often do mean things if you're good-aligned. However, you can intimidate the bad guys. Not necessarily evil people, but you can scare animals like bears or get people that aren't that bright to step aside.
Beasts and idiots. How dangerous.
Meanwhile the con artist is using deception and Persuasion to convince Lords to donate hundreds of gold to the cause. But I got a bear to run away instead of having a six second combat where I killed it.
I'm not sure exactly how smart you think a large group of people are, but a couple of them are indeed suicidally dumb. Like, dumb enough to challenge someone clearly superior to them dumb. That's not a fantasy trope, that's actual genuine real life. If every single creature you encounter in D&D always takes the most logical answer, the DM is too logical and maybe trying too hard. Because monsters and people are idiots.
Well, this is clearly a different experience. Generally, I don't see commoners acting like suicidal death cultists... unless they are secretly suicidal death cultists.
Generally... they want to live, and not cause issues by not stepping 3 ft to the side to let the incredibly obviously dangerous person walk past.
Yup. You are dealing with a creature that is way out of your league. I think it would take a lot of set up or luck (like stumbling across the information while doing research.)
Edit: Also, the Death Knight was from your scenario. I was using him as a rival to the lich. We can use 'Powerful, Goodly Paladin' instead.
Your informant isn't very good if he can't send a letter...or a sending...or an animal messenger or whatever. I'm sure that if you're about to threaten a Lich, you've probably thought about the logistics.
That plays into the point though. I don't need all of that set up for deception of Persuasion. But I do for intimidation to even have a chance.
Well, if your whole setup is to use a social conflict to deal with someothing that is way beyond your power level, then it's probably going to involve more than one roll. Or maybe not. Maybe a single roll would suffice. It's just an example after all and not an actual scenario. I'm fairly certain a single persuasion roll isn't going to defeat a Lich either.
But you might persuade the Lich to an alliance, or that sparing your lives is a better investment, or that killing you is too much trouble.
The goal isn't always to "defeat" the encounter.
I'm pretty sure the Potion Vendor example I used was to demonstrate that you could intimidate someone without the threat of physical violence. The example you're using now ignores that. The threat of being kicked out of your guild or being forced to close your shop doesn't involve any violence but is definitely a powerful bit of leverage. Also, I don't want to get into to discussion of good/evil because that's a pointless side-conversation.
Right, it didn't have to involve violence because you had leverage of him being a criminal. But, if he isn't a criminal, then what kind of leverage can you possibly have?
You can't get a member in good standing kicked out for no reason, so what is your plan to intimidate a man who has no criminal past, if not to start threatening other things.
And the good/evil conversation is not pointless. Many games have "no evil characters" as a clause. And, acting like a bad gangster film is going to qualifiy as evil, making Intimidation worth less in those games, because most of it's uses are not things good characters would do.
