Water Diviner

The Water Diviner is a tool from the Witchery mod. This tool is used to determine if there is a water block beneath a block. It has a seemingly infinite range below the block. You must have the Video Settings/Particles option to at least Decreased to see if there is water beneath it or not. If there is water, it will emit black particles, if there is not water, then there will be no particles. It will not use durability if there is no water beneath the block it is used on.
