Boots of Humankind
These large heavy leather boots are imbued with special magic that allows them to be only worn by non-humans. Anyone wearing the boots are instantly spotted by anyone they are trying to sneak past, with no saving throw or spot check. Any thieving skills that would allow them to be undetected will automatically fail. Even if the character is invisible, or otherwise unable to be seen, the boots will alert everyone within earshot of their wearers presence. Once the character is forced to interact, they will receive no social, racial, charisma penalties they would normally incur. In fact, they will receive a temporary +2 bonus to charisma while wearing the boots, specifically when dealing with another race. As long as a character is wearing the boots they will be treated as if they were human in every respect.
