Night Lantern
The Night Lantern is a device used by advance groups of Orrish raiders traveling overland. They are way-marker points for traveling at night. These are consecrated items of the Unholy Trio. They can be seen from 5 miles away. Their light is only visible to those dark-spawn with Dark vision.
These are not technically weapons, but they can be broken, releasing a sickening ring in a 30m radius that does not affect anything that can normally see its light.
