KLEPTOMANIA
Your character lives for the thrill of stealing things from other people. This flaw is differentiated from Greed in that a kleptomaniac cares more about the act of theft (not just acquisition) itself than the value of anything being stolen.
While a kleptomaniac has no problem with seeking a nice payoff from a crime, he’s often just as thrilled to snatch something small and unobtrusive from a purse or a wallet.
[3 Pts.]
Your character feels constant urges to steal things, and loves nothing more than the secret thrill of getting away with his thefts. At inns, he will steal eating utensils and unattended purses; the coats and bags of strangers are the apples of his eye. If your character is a professional criminal, so much the better– but big thefts are how he makes his living, not how he gets through the day.
If your character isn’t trying to steal from others (even his close friends, alas) often enough, the DM may begin enforcing theft attempts upon him (possible Will Save allowed to resist the kleptomaniac impulses in moments of danger or crisis). This can be a very tricky flaw for a character to live with, so 'caveat emptor'.
