Nether Star

The Nether Star is a drop of the Wither, the boss of The Nether and it will be essential to craft the Beacon in the future.

Use
By itself, a Nether Star has no use. However, it is a required ingredient to craft Beacons. As it is acquired from Withers, which require non-renewable Soul Sand to spawn, this item is also non-renewable.

Trivia

 * Although The Nether and the Wither resemble darkness, and utilize colors such as red and black, the Nether Star is brighter and has colors like green and yellow.
