Your prostheses are so realistic and your attunement to them so strong that onlookers scarcely notice the aids.
Benefit(s): You gain a +5 bonus on Sleight of Hand checks to conceal the properties of your prosthetic limbs or body parts, and creatures must succeed at a Perception check (DC = 10 + your Sleight of Hand modifier) in order to identify a prosthetic you are wearing. Creatures farther than 15 feet away from you cannot identify your prosthetic body parts.
Normal: Most intelligent creatures can immediately identify a prosthetic limb or body part just by looking (if 15 feet or closer and the body part is visible) or succeeding at a Perception check (DC = 10 + your Sleight of Hand modifier). Unintelligent creatures can make a Perception check (DC = 15 + your Sleight of Hand modifier) to identify a prosthetic, though this may have little to no effect on how they interact with you depending on their level of unintelligence.
