About this Mod

Corrosylva

Corrosylva is a progression-focused Minecraft mod centered around industrial corruption, environmental hazards, gated research, and large-scale machinery. Advancement is controlled through research systems, protected structures, and powerful but risky tools.


✦ World & Materials

🌳 Corroded Wood

Corrosylva introduces a new wood type:

  • Corroded Wood
    • Includes Corroded Planks and related blocks
    • Integrated into industrial and corrupted build sets

☣ Polluted & Corroded Blocks

Several blocks introduced by Corrosylva are polluted or corroded and can spread over time.

  • Spreading behavior is visible when increasing randomTickSpeed (recommended ~100–400)
  • High values may cause performance issues depending on simulation distance
  • These blocks transform nearby compatible blocks into polluted or corroded variants

☣ Smog Storms

Around every 10-30 minutes or more, a smog storm will begin. The player will begin to take damage every 10 seconds and be inflicted with mining fatigue, naseua and poison. You can hide in a shelter or underground to be safe from the storm. Storms last around 2-4 minutes. Particles will decrease visibility when you are outdoors.

✦ Research & Progression

📘 Innovation Codex

Players begin the game with the Innovation Codex, which governs research progression.

  • Right-click in main hand to open a research tree menu
  • Research nodes require:
    • Research Points
    • Occasionally additional item costs
  • Completing research nodes may:
    • Unlock recipes
    • Reward items directly
  • The system functions but may require patience due to minor instability

🧩 Research Shards

Research Points are obtained via Research Shards, found through:

  • Looting certain structures
  • Fishing
  • Rare drops from creepers

Behavior:

  • Shards vanish one at a time upon entering inventory
  • Points are stored as a persistent, per-player stat
  • Current total can be viewed in the Innovation Codex

📖 Item Info Book

Players also receive an Item Info Book at game start.

  • Right-click to open
  • Contains a single item slot
  • Displays information about the inserted item

✦ Industrial Machinery

⛏ Tunneler

The Tunneler is a progression-locked mining machine designed for deep excavation.

Unlocking

  • The crafting recipe is not known by default
  • Requires obtaining a Tunneler Manuscript
  • Manuscript is earned through Innovation Codex research

Power System

  • Requires 1–4 Battery Blocks placed adjacent (not above or below)
  • Battery Blocks:
    • Charged by right-clicking with a Power Core
    • Maximum charge level: 10

Operation

  • Shift + right-click with an empty main hand to activate
  • The Tunneler:
    • Moves downward
    • Mines:
      • 2 blocks outward horizontally
      • 1 block upward and downward
    • Destroys all blocks except:
      • Battery Blocks (which move with it)
      • Indestructible blocks (e.g., bedrock)

Energy Use

  • Each downward movement consumes 1 battery charge

Storage

  • Broken blocks are stored internally
  • Inventory size equals a chest
  • Opening the inventory disables the Tunneler

✦ Security & Automation

🛡 Factory Defender

The Factory Defender protects industrial structures.

  • Prevents specific blocks from being broken while active
  • Protected blocks include:
    • Tunneler, Battery Blocks
    • Industrial lights, sensors, wiring
    • Redstone components
    • Industrial concrete, terracotta, alloy blocks
    • Corroded Planks and other structural elements
  • The Factory Defender:
    • Cannot be obtained in survival
    • Drops gold and redstone, not itself
  • Breaking the Factory Defender removes all protection

👁 Motion Sensor

  • Detects entities entering its range
  • Detection range extends 3 blocks outward based on facing direction
  • Emits a redstone signal strength of 15 from its output side

🚨 Warning Light

  • Emits a repeating warning siren when powered
  • Intended for alarms and industrial alerts

💡 Industrial LED Lights

  • Can be powered or toggled via right-click
  • Adjacent lights automatically link together
  • Turning one on or off affects all connected lights

✦ Environmental Hazards

☠ Scorvetch

  • Applies the Polluted effect to entities
  • Effect:
    • Deals periodic damage (similar to Wither)
    • Drains hunger faster
    • Penetrates armor

🌱 Toxic Sand

  • May grow Toxic Ferns
  • Toxic Ferns poison entities that walk into them

💣 Industry TNT

When ignited:

  • Converts all blocks within 20 blocks into polluted or corroded variants
  • May ignite dirt blocks
  • Applies Industrial Fire to all entities in range

Industrial Fire:

  • Cannot be extinguished with water
  • Requires Purified Water

🚰 Purified Water

  • Created by smelting a water bottle in a furnace
  • Used to extinguish Industrial Fire

✦ Weapons & Tools

⚔ Burst Sword

  • Right-click to dash forward several blocks
  • Has a cooldown between uses

⚡ Charged Burst Sword

  • Upgraded version of the Burst Sword
  • Damages entities passed through during a dash

🪓 Charged Alloy Axe

  • While sneaking, breaking a log:
    • Destroys all connected logs and leaves (tree-felling behavior)
  • Consumes additional durability proportional to blocks destroyed

✦ Dimension Progression

🔥 Nether Lock

Frequently Asked Questions

Corrosylva server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.1). You can switch loaders with one click in the panel.

Is Corrosylva compatible with fabric?

Corrosylva officially supports fabric for Minecraft 1.21.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Corrosylva – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Corrosylva consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
