Boggarts, also called changelings, are shapeshifting spirits found in Ardenweald. They can turn into animals or members of other races, such as faeries and vorkai, allowing them to sow chaos and discontent; they are often seen turning into Drust-like illusions or ravager wasp-like illusions. A place full of disguised boggarts is considered haunted. They appear to be collaborating with the spriggans and are empowered by Mueh'zala, such as Noisul of Many Faces.
