The Nether Reactor Core was a block exclusive to Pocket Edition. It was the main component in the nether reactor structure. The block can not be crafted in the latest version, and can only be obtained via inventory editing or if retained from earlier versions. This block was also available in the Pi edition, however it could not be activated by any means.

Obtaining[edit | edit source]

If a nether reactor core was mined with any pickaxe, it would drop 6 iron ingots and 3 diamonds; otherwise, it would drop nothing.
