Shrub of Ink

The Shrub of Ink is a plant from the Witchery mod. These are trapped dead bushes, and look identical to normal dead bushes. When an entity walks over this plant, it will be given the Blindness effect for 20 seconds. The plant is consumed whenever an entity walks over it. The Shrub of Ink can only be harvested by breaking the block it is on top of, which can only be dirt, grass, or sand.
