Nexus Infection

Explore the Overworld with infested structures, biomes and obtain items filled with Nexus energy.

Start of the Infection:

The First Signs: Visitors

When logging into your world everything seems fine at first, but as soon as you place a bed, otherworldly creatures may visit you during the night.

These Visitors are strong hostile mobs who can spread the Nexus and can also spawn other mobs related to the infection. One of these is the Infector, a mob capable of spawning Nexus Tumors.

Nexus Tumors and the Spread:

Nexus Tumors rapidly spread the Nexus Infection across large areas, transforming them into hostile microbiomes. When a Tumor appears, it begins corrupting the terrain beneath it, converting the ground into masses of Dead Nexus.

While the Tumor is alive, Red Cacti, Nexus Roots, Mind Saplings, and Nexus Meat can naturally form on top of Dead Nexus blocks.

Mind Saplings grow into massive Mind Trees after roughly 2 minutes, while Nexus Meat can spawn Wreckeds or Infectors. Infectors spawn new Nexus Tumors, allowing the infection to spread even further.

If you're near the infection, a red fog will appear.

The infection can overtake some animals, turning them into hostile undead mobs that target other animals and spread the infection across the world.

Nexus Hives:

Once a Nexus Tumor finishes corrupting its surroundings, it dies and creates a Nexus Hive underground if there is enough space. Nexus Hives have 2 variants: Grand and Small. Grand Hives are created when there are no Torment Tentacles in a 100×100×100 block area.

Small Hives are created when there is at least one Torment Tentacle in that area.

Grand Hives feature Heartlens, Nexium Cores, Hive Blobs, and a Hive Root, which can be used to summon the Torment Root with a Nexium Heart. Small Hives feature only Heartlens and Nexium Cores.

The Coarse:

Once a Nexus Hive is spawned, the infection enters its 2nd stage, and Dead Nexus begins spreading the Coarse, a block created when Dead Nexus spreads while a Nexus Tumor or Infector is within a 100×100×100 area. The Coarse spreads while a Heartlen is within a block area of 200×200×200, creating Coarse Spikes, Dead Nexus Roots, Radiant Mushrooms, Nexus Meat, Nexus Acid, and large Nericin Tentacles.

The Hive Root:

Within Grand Hives there is a Hive Root block. It is the Heart of the Hive that emits heartbeat sounds, and is used to summon the Torment Root with a Nexium Heart, which can be crafted from 3 Nexium and a Heartlen Piece, both of which can be looted from the hive.

The Torment Root is a mini‑boss that drops a Nexium Tentacle, which can be used to convert Nexium into a Nexium Ingot using a Nexium Tentacle and 8 Nexium.

(Note: the Nexium Tentacle is not consumed when crafting a Nexium Ingot.)

The Nexium Tentacle can also be used to break Nexus-type blocks instantly.

Nexium Ingots can be used to craft Nexium Marks using 2 Nexium Ingots and 7 Cobblestones.

Nexium Marks prevent Visitors and Infectors from spreading the Nexus in a 60×60×60 area (Note: Infectors can still spawn Nexus Tumors.)

They also prevent Coarse and Dead Nexus blocks from spreading within a 50×50×50 area.

Nexium can also be used to craft Nexium Hexas, which can be used to infect mobs. One can be crafted using 2 Nexus Skins, a Coarse Spawner that grows on top of Coarse Spikes, and a Nexium Ingot.

Players can also create a Tumor: just kill a Nexus using a Nexus Amulet, then use a Bucket on the resulting Dripping Nexus to make a Tumor Nexus block that will spawn a Tumor.

Each Nexus Tumor has a variable lifespan.

In biomes like savannas and swamps, you can find the Overgrown Castle, which has been completely overtaken by an infection spreading through the Overworld. Inside, you’ll discover a locked chest that can be opened with a Radiant Key.

The basement appears empty at first, but you’ll soon notice a villager trapped down there… or perhaps the villager is the trap.

Getting too close triggers a boss encounter with the Deceiver, who can be defeated by destroying nexus blobs while it is near them.

Upon defeat, the Deceiver drops a Nexus Amulet, which can be used in 3 different ways:

It can kill a Nexus to obtain Radiant Ash, freeze mobs while the player has Bone Shards in their inventory, or be used to craft a Cloudmaker.

Nexadar Boss

If a Heartlen is active within a 100×100×100 area, and no Nexium Mark exists within 60×60×60, then the infection will generate its central avatar, a Humanoid Nexadar. This boss appears on the surface near the hive and, unlike other bosses in the mod, it can despawn.

It is able to clone itself to confure you, clones can be identified because they are slowed by the Nexus Amulet and they hold a slightly different weapon. It can be damaged using a Nexium Tentacle. **Once the humanoid form is defeated, it quickly forms a hive that summons the Nexadar’s true form, a powerful undead boss that keeps the infection active. You can also disable the infection by setting the nexusState gamerule to false. ** When the Nexadar dies the Nexus Infection deactivates. This means:

• Visitors and Woundeds no longer spawn in the Overworld
• Dead Nexus, Coarse, and Dead Coarse blocks stop spreading
• Nexus Tumors cannot be spawned using Nexus/Nexium Amulets
• Innate Nexus blocks will no longer spawn infected mobs
• Acid Stalkers can no longer spawn from Stalker Disguise blocks
• Humanoid Nexadar bosses no longer spawn near the infection
• Nexus Blobs can be killed using a Nexus/Nexium Amulet, turning them into Dead Blobs, which drop up to 2 Withered Tissues when broken without Silk Touch

Nexus Blobs

Nexus Blobs naturally generate inside Nexus Hives, Overgrown Castles, and underground Jasper Hives that can generate between Y level 32 to -4. Using 8 Withered Tissues and a Nexus Amulet you can craft a Reborn Blob. Placing a Reborn Blob reactivates the Nexus Infection, while breaking it deactivates it again.

The Nexadar drops a Nexus Amulet Upgrade that is required to upgrade the Nexus Amulet along with a Nexium Ingot. The Nexium Amulet works similarly to the Nexus Amulet, but freezes mobs for longer in a larger area, and can also kill Nexus mobs more efficiently. It also has increased durability: 695 (compared to the Nexus Amulet’s 189)
