Nether Reactor Core

The Nether Reactor Core was a Pocket Edition exclusive block used in the Nether Reactor. I t was added in Update 0.5.0 and it was removed in Update 0.12.1.

Crafting

 * 3 Diamonds + 6 Iron Ingots => 1 Nether Reactor Core (Now Uncraftable)

Usage
The Nether Reactor Core is a component of a Player-made structure that activates a Nether Spire. When the wrong structure is created, a message will be broadcasted saying, "Incorrect Pattern". When the correct structure is created and all players in multiplayer mode are near the Reactor, a message will broadcast saying, "Active".

Reactor
Once activated by being surrounded by the proper amount of Cobblestone and Gold Blocks, the player can activate the reactor by clicking on it. It temporarily transforms into Glowing Obsidian.

The Nether Reactor Core was removed from Survival and Creative Mode in Update 0.12.1.

Trivia

 * It has 3 stages: before activation, activation, and burnt out.
 * The tower it generates was made of Obsidian before Update 0.6.0.
 * After Update 0.12.1, a placed Nether Reactor will not be removed, but when mined, it will drop 3 Diamonds and 3 Iron Ingots.
 * It can still be obtained by mining one with Silk Touch.
 * A Nether Reactor Core mined with a Silk Touch Pickaxe will drop itself instead of the materials used to craft it.
 * Through modifications, the Nether Reactor Core can be placed and can function like it did before Update 0.12.1.
 * The texture was changed in Update 0.15.0.
