Exploiting narcissists.

If you want to exploit a narcissist, you should play on their feelings of self-importance, reinforcing their delusions and gaining favour by making you less repugnant to the narcissist than others who do not appreciate the narcissist's brilliance. However, in my eyes, this would make you a manipulative psycho.

How Is Narcissism Diagnosed?

Narcissistic personality disorder (narcissism) is diagnosed using The Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria. A person must meet five of nine of the following traits for a diagnosis of narcissistic personality disorder.

1. A grandiose sense of self-importance 
2. Preoccupation with fantasies of unlimited success, power, brilliance, beauty, or ideal love
3. Belief that he or she is “special” and unique and can only be understood by or should associate with, other special or high-status people or institutions
4. Requires excessive admiration
5. Has a sense of entitlement
6. Is interpersonally exploitative – takes advantage of others
7. Lacks empathy
8. Envies others or believes others are envious of him or her
9. Shows arrogant, haughty behaviors and attitudes

I think you have to reach out in kindness to the ones you think are in the wrong.

Even narcissists have feelings. And they don't deserve game playing.

I know one true narcissist. How she interacted with her children was chilling. They are shaped for life by her actions. She blames anybody and everybody for everything in her life that she does not like. Absolutely no personal responsibility and endless deflection. And the desire to control their father was at the root of everything. When he left her and she 'lost' control of him, she almost allowed it to kill her. So yes, 'taking' control of oneself away from a narcissist will always unhinge them. However, if you are embroiled with this person in either a family or business partnership and cannot escape them, then this will inevitably lead to further woes for you. I think NSAman's description of his business partner sounds spot on. I cannot say that this woman is 'evil' or 'malicious' - she is well able to be charming to others and to have others believe her side of stories, but the desire to control others, both physically and how they think, is compulsive. The greatest tool her husband ever had against her was his indifference to her. It may not have been completely true, but if he gave her the impression he was indifferent to whatever she was up to at any given time, it was by far the most effective way of disempowering her. She would happily engage in conflict for ever more than to face his indifference.

Asshole is not any use for this discussion.

I know of one person that fits the bill and she is an absolute nightmare to deal with. We had to cut her off in the end, zero contact. There is probably more to her than just narcissism to be fair, Id say there is a good dollop of sociopath in there.

But she is unbelievable, for years and years lying to different groups and playing them off against each other, always positioning herself to be the saint and martyr. She always setup her circle, kept one person there and controlled and the rest at distance. Its when she wants to swap out her go-to person that sh!t hits the fan so to speak. The manipulation, the lies, the wrangling tiny truths into complex webs of deceit. If I was to give you examples, I know it would sound very difficult to believe. Like looking at a movie thinking no real person would act like that. Oh boy they do....

Anyway, what did you do to combat him? You mentioned attacking him?
