Syntax:
pilfer <person>'s <container>
or
pilfer from <person>'s <container>
Pilfering is the art of removing something from someone's possession without that person knowing. It is also known as pickpocketing. In general, the larger something is, the harder it is to pilfer it. Likewise, the larger and more visible you are in relation to your victim, the harder it will be to mask your intentions. Reactions to pilfer have been hard-coded into all NPCs; most will respond violently to you. Failure to report NPCs that don't respond when you are caught stealing from them is considered bug abuse and you may be dealt with severely.
Example:
pilfer Crius's moneybag
