The Nether Reactor Core is a Pocket Edition-exclusive block used in the Nether Reactor. It is very expensive to build, so it is very rare to be able to make one.
The Nether Reactor is crafted from 3 Diamonds and 6 Iron Ingots, which makes it fairly hard to obtain.
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.
- Making more than 1 is a waste because the core can be used more than once.
- It can be used as a decoration.
- Hitting the block when it is not placed in the correct Nether Reactor pattern will make a client message saying 'Not the correct pattern!'
- On multiplayer, if the player activate the Reactor when the players are out of range, it will say 'All players need to be close to the Reactor'. This is probably because of the way it skips day into night.
- It has 3 stages; before activation, activation, and burnt out.
