Crimson Flesh Plague

Quickstart

1. When the plague difficulty prompt appears, choose one of the four modes: Easy has fewer, weaker infected; Hard has more, stronger infected; Apocalypse has two Flesh Hearts per biome; and Invasion brings meat meteors and escalating swarms.
2. Explore infected areas and fight their creatures for materials. Mine Brain Ore with an iron-tier pickaxe to get Brain Cells; abandoned laboratories and coastal ports are also worth searching for supplies.
3. Turn plague materials into Biomass. You need parasite flesh, a mutant bone, two infected flesh scraps, and a Brain Cell:

1. Make Biomass gear for combat and gathering, then build a Heartbeat Compass from a compass and mutant bones, tendons, or hearts. Use it to get the coordinates of a Flesh Heart; it cannot locate one until a heart exists.
2. Watch for Flesh Cocoons and the surrounding infection. They can be mined with an iron-tier pickaxe.

Overview

A Flesh Heart infects nearby terrain and produces cocoons. As the plague expands, further cocoons can appear far away and deep underground. Infected grass, dirt, stone, deepslate, sand, wood, leaves, and plants can mark affected areas.

The plague also infects animals and other creatures, while mutant enemies provide materials for stronger equipment. Infected terrain and plague activity progress through seven phases.

What It Adds

• Plague sites: Flesh Hearts, Flesh Cocoons, and infected versions of many natural blocks.
• Infected creatures: infected livestock, horses, wolves, rabbits, zombies, skeletons, creepers, spiders, villagers, Endermen, bees, and aquatic creatures.
• Mutants and other threats: Plague Husks, Mutant Brutes, Meat Abominations, Mega Mutant Bulwarks, Mega Mutant Stalkers, Mega Mutant Titans, Infected Spitters, Infected Queen Bees, and Carnivorous Worms.
• Materials and equipment: Biomass and bone armor, weapons, tools, a flamethrower, purifiers, and workbenches.
• Exploration and loot: Brain Ore, Salt Deposits, Titanium Ore, abandoned laboratory loot, and coastal port supplies.

How To Use

Find a Flesh Heart

The Heartbeat Compass reports the coordinates of a Flesh Heart when used. Its recipe uses a compass in the center and mutant bones, tendons, or hearts in the surrounding slots: . If there is no heart for it to detect, the compass says so.

Research equipment

Craft and place a Research Table. Add infected trophies and fuel to build research progress; accepted fuel includes coal, lava, and blaze powder. The table’s blueprint selector offers choices at research thresholds:

• 30: Basic Heater Blueprint
• 70: Advanced Heater Blueprint
• 100: Military Workbench Blueprint

Completed flamethrower research awards a Flamethrower Blueprint. The Research Table recipe is .

Process materials

Place a Flesh Rendering Barrel and use its interface to supply fuel and materials. It accepts coal, lava, or blaze powder. Parasite flesh and infected flesh scraps can be processed into rotten flesh, and rotten flesh into beef. Craft the barrel with .

Fuse armor

Use a Living Armor Fuser to combine Bone and Biomass armor pieces of the same slot into Living armor. Insert one of each matching piece; use an empty hand to retrieve an item from an occupied input. Craft the fuser with .

Crafting And Obtaining

Plague gear

Biomass is made from parasite flesh, mutant bone, two infected flesh scraps, and a Brain Cell. Mutant bones can also be made from four Mutant Bone Shards and an infected flesh scrap: .

A Mutant Cleaver uses Biomass, mutant tendons, and a mutant heart: . Mutant bones can be turned into six Bone Meal: .

Flamethrowers and advanced equipment

The Flamethrower requires a Flamethrower Blueprint, a Blaze Rod, an Iron Ingot, and a Diamond: . Its fuel is Blaze Powder. A Fuel Tank is required for the Super Flamethrower; craft one with glass and Blaze Powder: . The Super Flamethrower recipe is .

Mega Mutant materials are used for advanced items: a Mutation Sphere takes a Mega Mutant Core, Mutant Carapace, and mutant heart , while Plaguebreaker uses a Mutant Carapace, Mega Mutant Core, and mutant heart .

Purifiers, military gear, and other supplies

Research for the Basic or Advanced Heater Blueprint, then craft the matching purifier:

• Hot Spring Purifier:
• Advanced Hot Spring Purifier:

At research progress 100, the selector offers a Military Workbench Blueprint. Craft the workbench with that blueprint and iron ingots: . Its interface upgrades iron armor to Spec-Ops armor, then upgrades Spec-Ops pieces to Obsidian Military armor using two Obsidian Alloy per piece. Make four Obsidian Alloy from a diamond and four obsidian: . Titanium Ore smelts into Titanium Ingots: .

Salt Arrows are made from an arrow and two Sea Salt: . Salt Deposits yield Sea Salt; Salt Arrows inflict the Salt Shock effect.

Progression And Strategy

• Start with Biomass gear, then collect mutant materials for Bone armor and the Heartbeat Compass.
• Check infected terrain carefully: a Heart or Cocoon may be nearby, while later cocoons can be far underground.
• Use the Research Table to choose blueprints as your progress allows. Save fuel and infected trophies for the equipment path you want.
• Search abandoned laboratories for plague materials and equipment supplies; coastal ports can provide Sea Salt and Salt Arrows.
• Choose Easy for a lighter outbreak or Invasion for meteor impacts and growing waves of infected. Difficulty is chosen once.
