What rules apply for doing a ride-by grab of an item to steal it while mounted? Are there any prestige classes with related abilities? I am building a gang of goat-mounted dwarven bandits--- The Buckriders.
I don't think Sleight of Hand even applies. You wouldn't have time to identify items (or even be able to put your hands in someone's pocket) and of course stealth is out of the question.
I think the right rule is grapple, or maybe disarm. You would zip by someone, cut their backpack straps, bags, etc, grab that and run off with the bag. Once you're far enough away to be safe, you can examine the bags and see if there's anything worthwhile.
Alternatively, you could use Ride-By Attack and Improved Disarm to grab an item from the hand(s) of a wandering nobleman or mage.
