First you and the character you are targeting for some intrigue roll initative adding Cha bonus to the roll.
When its your turn you roll the social skill you are attempting(Diplomacy,Bluff,Intimidate..ect) using the targets Intrigue Defense as the DC.Intrigue Defense = [10]+[Status(lvl+trait)]+[Disposition Mod]+[Int]+[Ranks in Diplomacy], [Sense Motive],[Knowledge Nobility], [Knowledge Local]*if they are class skills.
If successful you damage 1d4+1 for every 5 over the Defense you were to the target's Composure which is will(Mod)+cha(Mod)+1 for every three levels.
Basicly it is like a social attack, where your skill is your weapon, Intrigue Defense is the AC and Composure is Hit Points. If your target reaches 0 composure he relents and you succeed in seducing, lieing, ect. This is simply the mechanics, there is roleplaying involved and I will add 2 damage or 2 composure as a GM Fiat for good roleplay/poor roleplay.
