Nether Star

The Nether Star is an item drop from the Wither that is currently used only in crafting beacons. It has the same animated glow that enchanted items and potions use. The dropped Nether Star can not be destroyed by explosions. However, it can still be destroyed by fire and lava.

Trivia

 * The Nether Star drop is not affected by the Looting enchantment.
 * The Nether Star is extremely rare and is considered one of the rarest items in the game due to the length of time it takes to acquire the skulls needed to create the wither that drops the Nether Star. The boss fight itself is not that difficult, due to the many different methods that make the fight much easier.
 * The Nether Star is the only item other than golden apples, written books and potions that has the shimmering texture on it and has no relation to enchantments (enchanted books and enchanted armor/tools have it too.)
