Nether Star

The nether star is an item drop from the wither that is used solely to craft beacons.

Withers
The nether star can only be obtained by defeating the wither, which is a boss mob. One nether star will be dropped each time, and is not affected by the Looting enchantment.

Usage
Nether stars have the same animated glint that enchanted items and potions have.

The dropped nether star cannot be destroyed by explosions. However, it can still be destroyed by fire, lava, and cacti.

It is also used to craft a Beacon.
