Cloaking

Cloaking is the power to hide the presence of oneself or others, preventing others from discovering one's location. This ability is possessed by both the forces of Good and Evil, to prevent the other from learning of their activities.

Cloaking prevents other beings from perceiving the cloaked, making them both invisible and unable to be found through sensing or scrying for their location.

Powers
Whitelighters can hide their charges making them invisible to a select few. Leo Wyatt used this power to hide Daisy, a mortal woman, from her Darklighter lover Alec. While she was cloaked, he could not sense or even see her

Spells and Rituals
Forces of both Good and Evil have been known to mask their presence through the use of spells. Dark dignitaries have been known to use this power to ensure privacy for rituals. The Dark Priestess Dantalian was able to cloak her lair as she performed a binding ritual between the warlock Zile and Prue Halliwell.

Artifacts
While trying to locate the first owner of the Magical Amulets, Prue was unable to scry for her because the amulet blocked off the magic.

When the Titans launched their attack on the Elders, Leo Wyatt organized the surviving Elders to be protected in a sanctuary, which was cloaked by fairy dust.

Piper Halliwell placed crystals around the Attic to cloak Chris from being sensed by Scabbar Demons. She later did the same for two young witches named Ryan and Jen to protect them from two Noxon Demons.
