Strength - Intimidation
Dexterity - Humour (taunting / softening up a gruff person)
Intelligence - Persuasion
Speed - Flattery (rather weak)
Perception - Deception (lying/detecting lies)
Willpower - Promises/Sincerity (?) (This is a tough one)
Unefortunately I do not like this idea of stereotyping the character, I mean we can have a sweet srtong warrior and a severe wizzard, that is the idea of larian's games !! We are our choice, our acts, we are what we chose to be, there is no predefined character, only the character we want and our beahviour influence the world around us
