Yakshi

A spirit which has taken the shape of a beautiful woman. The yakshi follows the orders of its master whom it formed a blood pact with, and guards locations of great importance. They are famous for how they change in strength depending on its master's primary emotion. In particular, yakshis that form pacts with those who holds a grudge or bears deep hatred often exhibit powers greater than other yakshis, but because they all look alike, it is hard to tell how strong they are, so facing them without proper preparation is an unwise decision to make.
