Changeling

Changelings are born to an Arch Devil by a human spell caster, and they live in the lowest planes of Hades. There they advise the Arch Devils and act as go-betweens linking devilkind and humanity. Though weaker than other greater devils, they hold a high place in the devils' hierarchy, because they embody Asmodeus' ambition to rule mankind.

Every Changeling can read minds and can take the shape of any man or woman it has seen even once. Its mind-reading works at will out to 100 feet, and it can take any humanoid form whenever it likes. Together these gifts let it copy a person's looks, personality, voice and memories perfectly. Their Arch Devil masters put this to good use, often sending them to the prime material plane to swap places with human children or important people.

Changelings also have a natural gift for wizardry, and 95% of them cast Black Magic and Enchantment spells at 3rd to 7th level; those who can cast spells use magic in a fight whenever they can and resort to physical force only when pressed, biting to drain blood and raking with their claws. A changeling also detects invisible things within 100 feet and can speak in tongues at will. They hate incubi and succubi and try to kill them at every chance. A summoned Changeling will perform any service involving its shape-changing, such as taking the summoner's form so the caster can seem to be in two places at once, or impersonating an enemy. Its service lasts no longer than an hour, unless continuing would serve the interests of devilkind.
