If it takes a bluff check to deceive someone, what does it take to convince someone that something I say is true?
Example:
Me: I shout, "I sincerely strive to be fair, honest and merciful and if you surrender I promise to offer you mercy. I have no desire to kill you so please throw down your weapons and surrender for there is no reason you need die today."
Me: Does he believe me?
Would you agree that the most common response from a GM would not be that "Yes he is utterly convinced that you are speaking the truth."?
Yes I would love it if they thew down their weapons and surrendered but I know that isn't going to happen. My concern is not so much what they do with the information but that they know such an option is available.
While this hasn't specifically come up in play yet, I'm wondering how to accomplish what I'm seeking.
Now technically I could do the following:
Me: I shout, "I hate you and want to kill you, bring you back to life and kill you again, steal all your possessions, mince your dead corpse with my little pinky finger into a thousand pieces and even if you surrendered now I would absolutely refuse to accept your surrender or offer you any mercy. I'm just vicious and evil like that."
Me: Since what I just shouted was completely 100% opposite of the truth, I'll need to roll for a bluff check and... what do you know but I have a -2 in bluff and I just rolled a 5... looks like I just failed my bluff check and they know how I really feel and what I would really do. Shame shame...
But that seems a bit silly. Anyone with more experience in pathfinder aware of an easier way to convince someone what I'm saying is true? Outside of a 1 minute diplomacy skill check which is generally completely unusable or not allowed during combat? While a bit contrived, intentionally trying to fail a bluff check is a feasible option that only requires a 1 round action.
The Cavalier Order of the Blue Rose states:
Challenge: Whenever an order of the blue rose cavalier issues a challenge, he receives a +1 morale bonus on attack rolls made against the target of his challenge, if the target is an intelligent creature to whom the cavalier offered the chance to surrender (by taking a standard action to offer terms). This bonus increases by +1 for every four levels the cavalierpossesses (to a maximum of +5 at 17th level).
So while this indicates it's a standard action to offer terms of surrender, it doesn't do anything regarding confirming that the foe actually believes your offer is real.
I'm hoping to join a home brew campaign soon in which case I can try to have the GM house rule that they always believe me which would be AWESOME and that if not I can present the solution below where I used the rules for bluff as a template but... anyone have any alternate ideas?
DIPLOMACY (Cha)
Persuade: You know how to tell the truth in a convincing manner.
Check: Persuade is an opposed skill check against your opponent's Sense Motive skill. If you use persuade to tell the truth, with a successful check your opponent can sense your honesty and is convinced you're telling the truth or at least that you believe you are. Persuade checks are modified depending upon the believability of the truth.
Circumstances Persuade Modifier
The target wants to believe you +5
The truth is believable +0
The truth is unlikely –5
The truth is far-fetched –10
The truth is impossible –20
The target is drunk or impaired +5
You possess convincing proof up to +10
Action: Attempting to persuade someone takes at least 1 round, but can possibly take longer if the truth is complex (as determined by the GM on a case-by-case basis).
Try Again: If you fail to convince someone, further attempts to convince them are at a -10 penalty and may require convincing proof (GM discretion).
