Somehow, all Ghost Hunters know how to make Ghost Vision Goggles, Ghost Guns, the Ecto-Slayer Shotgun, Devil Sword and Ghost Armor. It just comes to them at the onset of their ghost-busting career. No ISP Cost. See Special Weapons. Note: Can only build one of each at level one. Can add an extra one of these items as a spare at levels 2, 4, 5, 6, 8, 10, 11, 12, and 14 . They can also make a replacement if an original is lost or destroyed, however if a lost original is recovered, it will no longer work. Remember, only the Night Hunter can use the weapon or item .
