Neurospore: The Living Infection

Neurospore: The Living Infection brings a server-side fungal parasite to every dimension on 1.19.2. Infection is a harmful status effect registered by the mod that can latch onto any living mob or player, spreads in close quarters, and slowly damages while applying fatigue, slowness, and weakness.

What it does

• Infection spreads via contact with infected entities, from ambient spore blooms that periodically target nearby mobs, and through retaliation when infected mobs are attacked.
• World-level “infection pressure” grows over time per dimension, increasing spread odds and pacing block corruption.
• Corruption converts natural terrain into mycelium/nylium/sculk and blooms nether wart growth around players and spawn areas, making the landscape look claimed by the parasite.
• The parasite adapts: attacks against infected hosts are recorded and reduce incoming damage for that damage style (fire, projectiles, magic, explosions, piercing, melee). Highly adapted attacks can trigger defensive spore bursts.
• Infection is persistent: the world stores infection pressure and adaptation state so dimensions feel progressively more overrun.

How to experience it

• Fight or approach an infected creature and the spores can jump to you; hitting infected targets can reflect spores back.
• Ambient outbreaks occasionally seed infection onto mobs near players or around spawn even if no carrier is present.
• As infection pressure rises, expect faster spread, tougher infected mobs, and more terrain converted to fungal/sculk patches.

Implementation notes

• Server-only Fabric mod with a mixin on LivingEntity#damage to record and adapt incoming damage and to reduce it based on learned resistances.
• Infection data is tracked per-dimension via persistent state, so adaptation and pressure survive restarts.
• Terrain corruption reuses vanilla blocks (mycelium, crimson nylium, sculk, nether wart block) to avoid custom assets while still signaling fungal takeover.

Known limitations / future ideas

• Adaptation is tracked per dimension, not per individual mob, so a highly adapted dimension toughens all infected there.
• No visual HUD beyond the status effect; custom particles or blocks could make the spread even clearer.
