Powered Armor

Characters can gain proficiency with powered armor by taking the Powered Armor Proficiency feat (see Chapter 6) or via certain class features. Powered armor imposes more significant drawbacks on wearers who aren’t proficient with it than other types of armor. If you are wearing powered armor with which you are not proficient, you take a –4 penalty to Armor Class, you are always flat-footed and off-target (see page 276), and you move at half speed. If the armor has a special form of movement (such as the flight speed of a flight frame), you cannot use that form of movement.
