If 33+ years of forum discussions are any indication, no.
fair
So I'm mistaken when I read multiple posts by you indicating that you roll to see how well the orc performed his intimidation? Because I've seen multiple posts by you indicating that if the orc rolled a 3, it was a laughable attempt, but if he rolled a 22 it was a very good one. That's very different from what I just wrote.
okay except, that IS my house rule it was inquired about multi times (I have failed, failed misrable, almost but not enough) it doesn't invalidate the rules, it is just why I can't help you form your own DCs,
I came into say originally that YES you can have PC vs PC or even NPC vs PC social skill rolls, all be they most likely rare.
No. I'm reasonably certain some people have been swayed by
@iserith's position in the past. At the very least he got me looking to see if there was a meaningful consequence for failure before calling for a roll. I wasn't doing that initially.
I am sure that something he argued at some point swayed someone... I am pretty sure nothing he has or will say in this thread is changing anyone's mind... and anyone who was interested but not invest left 40 page ago.
no, by raw:
If I cast suggestion and say "I suggest (is that part of the casting?) you go home and revaluate your life" you get a save, if you fail it you go home and think about it... that is it you get no choice.
IF instead I use persuasion "I suggest you go home and revaluate your life" you get to interpret and react as you will... maybe you go home, maybe you just take a moment to reconsider there, maybe you go to a brothels' or bar because you think better there.
or more likely:
The DM has an NPC cast suggestion and words it so the PC has to pay 3x more then they want for an item
The DM has an NPC intimidate a PC(now remember it has to be unclear if it will work or not no auto yes/no) and even saying the same wording
in 1 the PC HAS to pay the money, in the other the player decides what happens when his fight/flight responce kicks in
If it can make the PC have to change what it thinks, feels or does, it is in fact much stronger than the suggestion spell. Can social skills make a PC intimidated(alter what it thinks or feels)? Can social skills persuade a PC to do something that the player doesn't want the PC to do(alter what the PC thinks, feels and does)?
those skill effect them, they get to react how they will react to that stimuli... the spell says you over rider there will and force them to do what you say.
