The Charmed Ones used this spell to vanquish the demon who they believed killed their mother. Since it required the Power of Three to work, the girls had to accept their destiny as witches in order to use it.
Timor tuus fortitude tua feminae ultimum exitium.
The incantation can roughly translate to "your fear is the strength of women which will be your ultimate end".
- This was the first spell that the girls used which confirmed their status as the Charmed Ones.
