An Energy Talisman is a small manmade doll used in spells to suck away the power of a witch whose hair it is made of. Wendy Beauchamp recognised it when Joanna described the object from one of her dreams, and told her it was very popular in New Orleans.

One was used by Vidar to weaken Joanna, rendering her completely powerless and vulnerable against her old friend's attacks. But it was destroyed by Harrison Welles, freeing Joanna and giving her full strenght again.
