To extract powers from magical beings or objects
Power Extraction means to pull powers out of magical beings or objects by the use of spells, potions or abilities. It can be temporary or permanent if absorbed completely.
Instances of Power ExtractionEdit
Spells and RitualsEdit
Piper once recited a spell to exchange her power with Leo's, but inadvertently exchanged Prue's power with Phoebe's as well. Later Prue recited the spell twice to exchange powers with a Darklighter.
Years later, Piper and Phoebe cast the "To Exchange Powers" spell in an attempt to exchange powers, but Zankou interrupted the spell, which caused the powers fly into two nearby mortals. 
Cole, as the Source of All Evil, once enlisted a Wizard to help him give up his demonic powers. The wizard and Cole performed a spell to transfer the Source's power to the wizard. However, Phoebe vanquished the Wizard before transfer was complete. The powers when extracted, appear as a bright transparent human-like figure.
The Hollow will absorb any power that is used against it along with the original owner's other powers, leaving them powerless in the process.
A Power-Sucking Athame has the ability to absorb the powers of whoever is stabbed with it. The powers are stored within the blade until they are extracted. It is commonly used by warlocks to kill witches and steal/store their powers.
