Blinking

Blinking is the ability to transport one's self to a thought-of location or person in the "blink of an eye". This is how certain demons and warlocks teleport. Blinking is an instantaneous transfer, usually accompanied by a short, sharp sound. However, it can also be accompanied by a quick whoosh.

According to Melinda Warren, her lover Matthew Tate copied his power of blinking from another witch. This explains that the power to blink was originally a power of witches, but after it was stolen by warlocks centuries ago, it started manifesting within them instead of witches, making it a warlock's power.

Prue, Piper, and Phoebe Halliwell gained this power after they were turned into warlocks under the influence of a marriage bond between Prue and a warlock named Zile. It is revealed that when warlocks want to find someone, they don't have to know where to go, but can simply focus on that person and blink there.
