Emerald
From The Minery
Emerald is a new ore that was added with version Version 0.1-b158 of the server plugin. It can be used to make a Mob Wand and will likely have more uses in the future. It is dropped from Emerald Ore blocks upon breaking them.
As a Crafting Ingredient
A Mob Wand can be crafted from an Emerald and two sticks.
