They can be vanquished with a simple Power of Three spell.
After a few centuries, the Anubii became weaker and they visited a witch to ask for a spell that would make them demigods again, but when the witch couldn't help them, they killed her and drank her blood. After that, they found out that the blood from a witch made them stronger and they could live forever. They started collecting the blood of witches and Wiccans throughout America, until they were vanquished by the Charmed Ones.
