The nether reactor gives friendly mobs (players, tamed mobs, villagers, etc.) fire resistance, gives striders Speed III, and clears Wither I in a 64 block radius. It is activated using a complex structure shown on the next page.

Image guide for creating the multiblock

In order to form a full reactor, you make the above multiblock structure, building from layer 1 upwards.

TODO: Add recipe description

It is made using lots of valuables, including a nether star… good luck!

History

1.6.1*

Camel husks, nautili, and zombie nautili are now all affected by the nether reactor

1.5.2*

Camels, skeleton horses, zombie horses, and happy ghasts are now given fire resistance by the nether reactor, just like every other tamed mob

1.4.1*

The gobblerift, nether reactor, and soul seer now have emissive textures

1.4.0Release*

The nether reactor core no longer requires gilded blackstone to craft, using normal blackstone instead

Release-

Removed all Manic compatibility features. RIP.

1.1.0Beta 6*

The nether reactor can now be built with chiseled polished blackstone and raw gold blocks

1.0.1+

We now have a small amount of compatibility with the Manic datapack. Most of this won’t make sense unless you’ve played with that datapack.

  • Nether reactors now give sanity over time
  • Several new Manic-related emoji can now be used if it is installed
