Manny Green, the Twisted Tycoon (3.5e Vestige)/Influence

The binder becomes extremely selfish, and will refuse to do anything that is asked of him unless he somehow benefits from it. Essentially, he acts only in his own interest; he might come to the aid of an ally if he has a close working relationship with them and knows that they would do the same for him, but he won't help strangers or acquaintances unless there's something in it for him or he owes them something. (If he acts altruistically, he violates Manny's influence.)

In addition to the selfishness, the binder becomes deeply cynical, and will be simply incapable of believing anybody to be selfless; he is convinced that everyone else is as selfish as he (now) is, and so he is automatically suspicious of and hostile towards anyone who appears to be acting altruistically, even if (no, make that especially if) they genuinely are altruistic. The binder also considers anybody who does something without expecting or desiring any sort of reward to be an idiot and a fool, as well as somebody who he will probably have to... dispose of, especially if they have healing abilities.

The binder becomes obsessed with controlling all sources of supernatural healing. He will insist on owning any healing-related magic item he comes across (other than something that he or one of his agents sold). If he encounters someone who has a healing item, he will attempt to purchase it from them or convince them to work for him. If he cannot, he will attempt to steal it from them, and will not be adverse to murdering them in the process. If he encounters someone who has some sort of ability to heal others, like a cleric or paladin, he will attempt to convince them to work for him. If they refuse, he will attempt to kill them. The binder will go to utterly ridiculous lengths to establish a monopoly on healing abilities, and once he decides to kill someone to remove them as "competition", he will do so relentlessly, hunting them down wherever they go and attacking them whenever the possibility presents itself, as well as hiring assassins to kill them. (If the binder becomes aware of a healer's existence and then lets them go about their business without doing everything in his power to employ, control, or slay them, he violates Manny's influence. Note that he can make an exception for members of his party.) If the binding ends, the binder will return to his senses and stop trying to kill the unfortunate healer he's targeted (unless he has some other reason to kill them), but if he re-establishes the binding, he will resume his efforts to murder the healer. However, while he is relentless, he is not suicidally so; if he is outmatched or simply losing a battle, he will not be adverse to retreating from that battle. However, once he is safe, he will regroup and resume his efforts to murder the healer who is the focus of his ire (if he does not, he violates Manny's influence).
