The language of the Steal action has changed from calling for a -5 penalty to the Thievery check to pick a pocket, or similar theft, to a DC increase of 5. The Pickpocket feat, which is meant to remove this difficulty increase, still refers to the -5 penalty. This disconnect in the language could create a situation where the pickpocketing character's check is being rolled against the higher DC despite having the Pickpocket feat.
