To Separate A Witch From Her Powers

To Separate a Witch from Her Powers is the name given to an entry in the Book of Shadows. It explains how the use of a potion and spell, can be used to by a witch separate and call for the powers of another witch.

Notes and Trivia

 * The To Call a Lost Witch ritual uses the same spell as this one but requires the additional words "Blood to Blood, I summon thee. Blood to Blood, return to me".
 * This spell inadvertently summoned the Source of All Evil when the sisters called for their powers after he had stolen them with the Hollow.
 * Besides the Charmed Ones, this spell has been used by Gail and her two friends Helen and Amanda, the Stillman Sisters, and the demon Zankou.

Mistakes made in the series of Charmed

 * The Stillman Sisters and later the Charmed Ones used the spell without needing the potion.
 * Zankou, on the other hand, used the potion without the spell. He also just had to throw it at the sisters rather than having them drink it.
 * Although Aunt Gail ripped the page out of the Book of Shadows and folded it, the page appears unharmed in later episodes. Although she did return the page back to Phoebe, the page bears no sign of ever being folded.
 * When Piper, Phoebe and Billie cast the spell To Call a Lost Witch in season 8 of Charmed, they left out the last two sentences, making it actually this version of the spell.
