-If you visit someone who does not have limited night abilities, you do not lose a steal. This is the most important attribute: You only lose steals if you succeed and you know when you have visited a target with limited night abilities. This allows you to determine if your target is one of the roles below: Of course, you can't tell which one of these roles was your target. Protectives, Retributionist and Jailor are very important targets; if you have a Consigliere, you can ask them to investigate them. This may be dangerous, since your target could have been the Veteran.
 * Doctor's selfheal, Bodyguard's vest - it is rare for the Mafia to attack the Doctor/Bodyguard the same night they protect themself.
 * Vigilante's bullet - Vigilantes rarely find three targets, stealing a bullet will seldom make a difference.
 * Veteran's alert - useful if you manage it. This is a big if, because you may just die instead.
 * Medium's seance - extremely situational. Sometimes it helps, sometimes it doesn't.
 * Retributionist's revive - extremely useful! You will probably find them by accident or if they are forced to reveal.
 * Jailor's execution - extremely useful! Should be your priority target.

-You may only visit the same person once. This attribute decreases your effect on the Jailor (and Vigi and Vet), since you cannot "completely drain" them. I believe (opinion) that this makes the Thief too weak at some of his most effective uses:
 * Jailor: Remove all their executions (you have to know that your target is really the Jailor). Obviously effective, protect your Mafia from execution.
 * Vigilante: If you manage to steal a bullet and you are allowed to steal another one, a Vigilante may feel pressured to shoot someone before they are rendered useless. This can be good especially if a non-Mafia falls under suspicion the following day.
 * Veteran: See above. They will most likely alert the following day, hoping you will visit them again. This may cause collateral Town deaths, while you tell your fellow Mafia not to visit your last target.

Doesn't seem overpowered to me and has some interesting uses. My only suggestion (opinion!) would be to remove the attribute mentioned directly above.
