Power Extraction

Power Extraction means to extract powers from magical beings or objects by the use of spells, potions or abilities. It can be temporary or permanent if absorbed completely.

Powers
Demonic Power Brokers have the ability to extract powers they place in other beings for storage purposes. The powers when extracted, appear as a single spherical white orb.

Spells and Rituals
Prudence, Piper, and Phoebe once recited a spell to relinquish their powers and they are extracted and stored in a mystical lantern. The powers when extracted, appeared as several blue-white orbs.

Gail Altman once extracted the sisters' powers with a potion and a spell and gave them to the demon Cryto.

Piper once recited a spell to exchange her power with Leo's, but inadvertently exchanged Prudence'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.

Potions
Zankou extracted Phoebe's power with a potion. He later used the same potion to extract Piper's powers. The powers when extracted from Piper and Phoebe, appeared as several blue white orbs.

Artifacts
The Hollow will absorb any power(s) that is used against it, leaving the original owner without their power(s).

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.
