The Moonlight Sword

The Moonlight Sword is a weapon that you craft by stacking two Moonlight Crystals on top of a Amethyst Rod. It deals 4 and a half hearts per hit and one special technique is that if you are about to die, just right click the ground and mobs inside a 25 block radius around you will get Slowness II for 8 seconds, which is enough to escape. This action can only be done one time before it has to gather enough power to do it again. (it usually gains enough power in 5 real life minutes to do it again)  The Moonlight Sword cannot be enchanted and the sword cannot be destroyed in any way. The only way to make sure it gets destroyed is to burn it at midnight or wait for it to naturally despawn. If a mob happens to pick up this sword, the sword can be used on YOU, so be careful when getting killed with this thing in your inventory! Legend says this sword evolved from the The Sunlight Sword, an opposite cousin of the Moonlight Sword.
