The Magic Wand... This wand you can point at a greifer on your sim and fire it, and it will blow them off your land with a bolt of light shot out of it. You can also use it in magic roleplay. So it is both a personal defense weapon and a magical artifact, and it works.
Now how to use it? Just add it and it should appear in your right hand. Then go into mouse look mode and there is a tiny cross hair in the middle of your screen. Press the left mouse button and a bolt of white light comes out the end of the wand and strikes the crosshairs, so whoever you are looking at gets blown off the sim.
You can also use this magic wand with my magic targets, and do target practice. The targets change to show where the magic bullet hit them. Then you can reset the targets back to normal when you are done shooting just by clicking the red button.
