Hex Bag

The contents of the Hex Bag used in the spell to kill Amanda Dutton in 3.09 Malleus Maleficarum .

A hex bag is a charm composed of a mixture of herbs, talismans, other supernatural ingredients placed in a piece of cloth and bound with leather. It is used to bring about a specific effect, usually, but not always, malicious. A hex bag intended to harm someone also contains a personal belonging of the intended victim (usually clothing).

Apparently the only ways to stop a hex bag are to find and burn it, have the witch casting the spell break it, or have a powerful counter-spell cast. When a hex bag is burned the flames become a bright blue.
