This faceted 7 Chakra Faceted Crystal Ball Hangingis an excellent feng shui cure for diffusing poison arrows. Hang it in front of sharp corners or the corners of support pillars that sends out shar chi to you. You can also hang it on your window to help diffuse shar chi (killing energies) coming from poison arrows outside.
Apart from that, it is also a nice home decor when you hang it at a window to catch the sunlight and forming a beautiful rainbow to project and lift up the energy in a room with positive vibes. This is especially important to a room of a sickly person. This will help invigorate, revitalize and bring positive chi in to rooms that do not have exposure to a significant amount of sunlight on a regular basis. A room that is too yin (lackof sunlight) brings lethargic and illness energy.
