About the nether reactor[]

I made the whole Nether Reactor then I spawned into the room of Netherrack. After 45 secs I got Melon Seeds, Nether Quartz and Sugar Canes only .I saw the Burnt out nether reactor which is made of 26 Obsidian and a Nether Reactor Core. I Mined netherrack to get nether brick.

So let me get this straight, the Nether Fortress, as I call it, does not despawn as a tree would without a trunk?

crafting recipe[]

the true crafting recipe was revealed in 0.9.0. People used to think it was rotate 90 degrees! –Preceding unsigned comment was added by (talk) at 23:24, 15 August 2014 (UTC). Please sign your posts with ~~~~


I watched the video and this seems to be a way into the Nether. The Zombie Pigs are somewhat derpy, but the guy spawned in an obsidian room with Pigmen attacking him. Stpehen –Preceding undated comment was added at 02:39, 15 November 2012 (UTC). Please sign your posts with ~~~~

It's a bit clearer in the second part of the video, but the reactor builds an obsidian cube around itself; there is no separate Nether dimension. -- Orthotope 05:53, 15 November 2012 (UTC)


Something that doesn't make much sense is that although it requires at least an iron pickaxe to mine diamond, and at least a stone pickaxe to mine iron, it only takes a wooden pickaxe to mine this. It doesn't make much sense, unless this is just vandalism or misinformation, why a wooden pickaxe can mine something made out of iron and diamond. It's almost like saying an iron pickaxe can mine obsidian. #trigger_hurt(I|T|C) Check out my project! 18:57, 27 November 2012 (UTC)

Probably just an oversight... remember, they only just fixed the same issue for the emerald block in PC Minecraft. Report it on Mojira? --Mental Mouse 22:10, 27 November 2012 (UTC)

Reactor spawns gold?[]

I haven't seen the reactor spawn gold, but the spawned pigmen drop gold... is this a mistake, or is spawned gold just really rare?

The reactor des not spawn gold, just the Pigmen. Meeples10 22:09, 6 March 2013 (UTC)

What happens if you light up the reactor?[]

That is, as soon as that room appears, start placing torches. Does that interfere with the Pigmen spawning? --Mental Mouse 22:11, 27 November 2012 (UTC)

I put down two torches in the few moments between the room appearing and items beginning to spawn. First items appeared, then three zombie pigmen appeared. I slew them, and began to run around gathering items when three more appeared, slew them and a final three appeared before the reactor burnt out. A steel sword was good enough to kill them easily.
--Musui 15:31, 1 December 2012 (UTC)
So, sounds like there's no particular problem with lighting the place up. Thanks! --Mental Mouse 16:23, 1 December 2012 (UTC)


After activating the nether reactor (and killing 9 pigmen), I had the following extra items in my inventory:

  • 5x Bamboo
  • 4x Gold ingots
  • 10x Small brown mushrooms
  • 15x Glow dust
  • 9x Pumpkin seeds
  • 6x Cacti
  • 7x Red and white mushrooms
  • 1x Bow
  • 1x Bone

I can't get enough gold how?[]

I can't use it because you need 36 gold!😱😱😱😱😱 –Preceding unsigned comment was added by (talk) at 15:27, 1 December 2012 (UTC). Please sign your posts with ~~~~

Check out branch mining. --Musui 15:32, 1 December 2012 (UTC)

Try to type seed 0.4.0 dig straight down first get wood then get stone then mine iron then smelt then dig straight more for gold and diamond! dig on grass near beach make room then mine (layer 14) and you get gold! Minecraftaddict154 00:55, 1 June 2013 (UTC)

Day/Night Cycle Changed[]

Just for fun, I decided to mine the Nether Reactor Core block immediately after activating it. I was able to reclaim the four gold blocks and have a Nether Spire with no holes in it, but it seems to have fubar'd the day/night cycle for that world.

Instead of the normal ten minutes of daylight and seven minutes of night with 90 second twilight in between, the world now seems to be in perpetual night. The only exception is after sleeping, when there is daylight for roughly 30 seconds, twilight for 5 seconds, and then perpetual night again.

Is this just a bug in version 0.5.0, or is it some form of in-game karmic justice for messing with the Nether Reactor? –Preceding unsigned comment was added by (talk) at 00:22, 25 December 2012 (UTC). Please sign your posts with ~~~~

As far as I can tell, the Reactor is supposed to set the time to night while it's active; breaking the core before it's done prevents the usual deactivation effects from happening. You could try building another Reactor and let it finish properly, see if that fixes the day/night cycle. -- Orthotope 09:04, 25 December 2012 (UTC)
Yes it is a bug i tried it in Hale's world and delete the core and got:

5x Seed

8x Cactus

5x Sugarcane

20x Quartz

18x Obsidian and tried to sleep turned to day in 30 seconds and sunset in 5 seconds and night for infinite time. 😢 I hid it in a cave near waterfall (seed: 0.4.0) then i broke the 2nd floor spire then it is fixed. Got it? --Minecraftaddict154 12:32, 31 May 2013 (UTC)

Remember to break the 2nd Floor Or Higher to fix it to 10 min day 7 min night 90 s twillight but not 30s day 5s twillight (sunset) and infinite night. Minecraftaddict154 00:52, 1 June 2013 (UTC)

Really annoying[]

It takes 36 gold each time. I got 2 gold blocks back. Make sure you have an empty inventory before using the reactor.

Supposedly you are able to retrieve at least some of the gold blocks before they turn to obsidian. 13:35, 28 February 2013 (UTC)
You need Iron Sword, and Diamond Pickaxe*. Save the Pickaxe for the Obsidian. Use the Iron Sword to touch The Reactor and kill the Pigmen. They drop gold ingot instead of nuggets because there are no nuggets in PE. If you have problems, break the 2nd floor not the room you collect stuff. Time is fixed.
  • Only use for Obsidian for Reactor.

Mined Obsidian Box, No Reactor Core.[]

Mined 25 blocks of Obsidian, no Core within, around, or under box. Reactor did produce items. P1nesap 15:16, 15 April 2013 (UTC)

Bug in breaking active core @_@[]

If you break active core it will not blow up, If you sleep, it turns day but shortly turns to night around 30 seconds after. Breaking gives . Can you try it? Minecraftaddict154 12:26, 31 May 2013 (UTC)

forever night time[]

Guys I made it and then I mined all of the obbsidion and then made the nether reactor around the core it left then clicked it and then it became forever night time! Help! –Preceding unsigned comment was added by (talk) at 21:17, 19 December 2013 (UTC). Please sign your posts with ~~~~


The article seems to be a stub, shall I add the {{stub}} template? --ToonLucas22 (talk) 11:01, 17 December 2014 (UTC)

Pigman spawning[]

About how many pigmen spawn from an active reactor? According to Zombie Pigman, they all drop a gold ingot, and if that is true, mining the gold blocks may not be needed to multiply your gold supply. KnightMiner (t·c) 14:14, 23 January 2015 (UTC)

Tile Entity NBT is absent[]

The Nether Reactor Core is supposed to have an NBT data structure, but I don't think it's on this wiki. Anomie_x or Jocopa3, or anyone familiar with digging into the source, can someone tackle that? – Sealbudsman (Aaron) SealbudsmanFace.png t/c 04:08, 9 May 2015 (UTC)

According the game binary, the Nether Reactor has a compound tag with three tags inside: a boolean tag called "IsInitialized", a short tag called "Progress", and another boolean tag called "HasFinished". I'd have to look at a save file to know what the values for "Progress" mean. Jocopa3 (talk) 03:29, 18 May 2015 (UTC)
Oh, cool! Yeah that would be good to know. Does it inherit the X, Y, Z and Id tags from TileEntity, like it would if it were a PC Tile Entity? – Sealbudsman (Aaron) SealbudsmanFace.png t/c 04:16, 18 May 2015 (UTC)
Yes, like all tile entities, it inherits the X, Y, Z, and ID tags. After looking at the game binary some more and testing with a save file, the "Progress" tag is a number between 0 and 920 measured in game ticks, because when progress reaches 920, the game signals the nether reactor to go inactive; that number makes sense too when you consider that the nether reactor is only on for 45 seconds, and the game runs at 20 ticks per second. Jocopa3 (talk) 05:13, 18 May 2015 (UTC)
Ah. I wasn't sure if it was different for some reason in PE. You probably have enough to add an NBT section if you want, otherwise I'll get to it. – Sealbudsman (Aaron) SealbudsmanFace.png t/c 10:50, 18 May 2015 (UTC)
I'm not very good at wiki editing and formatting. I listed all the info I found about the NBT for it, so you can add it if you want. Pocket Edition NBT format is pretty much the same as PC, the only difference is how PE saves the NBT files. Just remember that the NBT section should go on the Nether Reactor Core page, since that's the page for the actual tile entity itself. Jocopa3 (talk) 03:23, 19 May 2015 (UTC)
All set! Thanks again. – Sealbudsman (Aaron) SealbudsmanFace.png t/c 18:20, 19 May 2015 (UTC)
Since it's not in the PC version, I'm not going to be able to help. Anomie x (talk) 11:26, 9 May 2015 (UTC)

Opening worlds made in 0.11.0[]

What would happen if I opened a world made in 0.11.0 that had a nether reactor core? And I opened it in 0.12.0? Boorider7 (talk) 20:37, 9 September 2015 (UTC)


I have no idea. i'm mad.>:| they removed it and my train station I made out of them (I had no idea what they were until 2018 A WILE AFTER THEY REMOVED IT) just disappeared! im so mad I could just delete the game.–Preceding unsigned comment was added by (talk) at 18:02, 28 March 2018 (UTC).

Minecraft Wiki talk pages should only be to discuss the article itself, not to rage about your opinion regarding the feature.-- Madminecrafter12Orange Glazed Terracotta JE2 BE2.pngTalk to meLight Blue Glazed Terracotta JE1 BE1.png 22:26, 18 May 2018 (UTC)
these kind of people should be banned,nglThat’s Me!(Salamander0007) (talk) 02:19, 15 March 2021 (UTC)
The block is still in the game, and if you have already placed them down they will stay in your world it’s happened to a few of my older minecraft worlds, they still have the breather reactor core in them, and I can still place them down as I had them in my inventory, also I’m not sure why your angry about a removed feature you never properly experienced. The reason they removed it was because mobile devices had become powerful enough to handle the nether. Lunarome (talk) 00:38, 9 April 2021 (UTC)

Plastic Texture Pack[]

According to the history section, the texture of the block was changed to appear correctly due to an issue with the Plastic texture pack. Currently, the page itself uses the Plastic texture pack image, which I believe should be changed to reflect the intended state of the block; it was changed to look like the normal one, as it previously looked like the plastic one due to a bug. -- 22:41, 29 April 2020 (UTC)

If it currently uses the Plastic Texture Pack texture, then I think it should use it here as well as that reflects how it actually appears in-game. If it's since been fixed, then I agree, it should use the intended texture. -PancakeIdentity (talk) 22:59, 29 April 2020 (UTC)
According to the History section: "The textures of nether reactor cores have now been changed due to a bug where the block's textures switched with the Plastic resource pack's, and if the player used the Plastic resource pack, the original textures would be shown on the block." There are two things that could have occurred: the bug was fixed in Bedrock Edition and it now uses the Plastic texture file, or the bug was not fixed, and it properly uses the vanilla texture file. Unfortunately, I have neither Bedrock Edition nor the tools required to obtain the block, so I have no way of testing this. Until someone does manage to test it, I suppose the best thing to do would be to leave the page in its current state. -- 23:13, 29 April 2020 (UTC)
It says they have been changed BECAUSE of the bug, it doesn't say the bug is fixed, and likely never will be. FVbico (talk) 23:50, 29 April 2020 (UTC)
It seems I've been confused. I was under the impression that the History section was implying that the update "fixed" the bug by changing the texture; I should have been more observant. Sorry about that. -- 00:24, 30 April 2020 (UTC)
Well, I've been testing this, and the Nether Reactor Core still uses the Plastic texture on Bedrock Edition 1.16.201. Thejoaqui777 (talk) 03:03, 13 February 2021 (UTC)

Reactor Requirements[]

This page claims that the player had to be level with the reactor, which had to be between levels 4 and 96. However, both of these are false. The player had to be between levels 4 and 96 (I'm assuming the upper bound based on what I know), but did not have to be level with the reactor. However, activating the reactor without being level with it was tricky at best. That said, I used reactors to break a hole through bedrock, which required the last reactor to be on level 2 (the floor generated in 2 levels of netherrack, so this was enough to clear the bedrock), and it required that I stand a couple blocks higher than the reactor (otherwise I got a message saying something about being too low). Unfortunately I don't remember what exactly the message said, as this was of course several years ago, but I remember for certain that I made the reactor activate by standing higher than it and successfully broke bedrock this way.

I've never once edited a wiki page before, so I'm not sure what's the best way to go about updating this information. Can I just go change it?
