To date her greatest achievement is converting the bandit lieutenant who spared her life. We were using 3.5 rules until the APG came out, so GM ruled that if she took the time to talk to him, she could basically reverse his opinion of himself. It took two weeks, and there was some pretty hairy discussions considering he was more than mildly attractive and she was lonely, and to further complicate things, their home countries have been at war with each other for centuries. He was a paladin who lost his way, killed his lover and her husband, and gave into rage. After speaking with her, however, he found his way to the Light, though not necessarily the entire truth and began working towards earning enough money to buy a scroll of atonement so he could regain his paladin status.
She's had some pretty bad failures, too. When a lycanthrope was running around the capital munching on attractive females of a certain age, she removed his curse and let him go free, arguing that murders committed while under the influence could not count against the man. The same argument was used to save a druid known for attacking innocents who she found to be insane, who she also cured. Neither of those outcomes were highly respected by the people, and caused a great deal of party conflict, but it was the right thing to do.
Also, she agreed to raise some crazy aristocrat lady's dead dog in exchange for getting the party fighter's son back. She later reappropriated the lady's fine stuff and sold it to buy diamond dust to raise and restore party members.
