This item has been officially removed or made unobtainable.
It can still be obtained using third-party software. However, this can cause unexpected behavior such as bugs and crashes.

The nether reactor core is a block exclusive to Pocket Edition. It was the main component in the nether reactor structure. The block cannot be crafted and can only be obtained by using an inventory editor, or if it was retained from earlier versions. This block is also available in the Pi edition, however it cannot be activated by any means (due to the lack of Survival mode in the Pi edition).

Obtaining[edit | edit source]

Nether reactor cores are unobtainable except through inventory editing or having it previously in a world. If mined in Survival with a pickaxe, it will drop its crafting recipe: six iron ingots and three diamonds.

Crafting[edit | edit source]

Pocket Edition only. Functionality and ability to craft the Nether Reactor Core removed in 0.12.1 after the addition of the Nether.

Usage[edit | edit source]

This block was required to build the nether reactor. Tapping on it would activate the reactor if built correctly.
