Wax On, Wax Off (achievement)

Wax On, Wax Off is a dungeons & raids achievement earned by defeating a Waxing Twilight Soul during the Sisters of the Moon encounter in Tomb of Sargeras on Normal difficulty or higher. The Twilight Soul is a trash mob in the area and must be moved into the encounter which is initially purple. The Sisters transition into the Lunar Phase at 20% health and this turns the Twilight Soul to waxing and gives it a blue color, after which it can be killed and the encounter can be defeated.
