Blending
Prerequisites: 10 HD
Benefit: Make a bluff check. All observing creatures must make sense motive checks, but are not aware that they are making the check. If they fail, they do not notice that you are an unusual race by casual observation. In this way, a human can pass through a demon world undetected for a time. With greater observation, the observing creature is allowed another saving throw. Feel free to add difficulty modifiers as you see fit, for example a Balor cannot blend easily on the prime material plane, but a human can blend easily with elves.
