Briaius Infection
A living contagion for Minecraft Bedrock. Infection spreads between animals and mobs on its own, mutating its hosts through 11 visible stages — from a faint blue haze to a fully mutated, aggressive red strain — and it doesn't need your permission to start. Outbreaks can ignite spontaneously, anywhere in the world, at any time.
Features
Organic spread — infected hosts try to infect nearby animals and mobs every 2 seconds, with the chance to spread increasing the further the infection progresses.
Spontaneous outbreaks — every 30 seconds, each dimension has a chance to spark a brand-new outbreak on its own, on a random valid creature, with no player involvement at all.
11-stage progression — color, particle density, movement speed, and aggression all escalate together as a host moves from Exposure to Full Mutation.
Visible name tags — infected creatures are tagged above their heads ([Exposed], [Incubating], [Carrier], [Breaking Down], [MUTATED]) so you can track an outbreak at a glance.
Full Mutation payoff — fully infected hosts gain permanent Strength and Speed and periodically damage nearby uninfected creatures, actively trying to force the infection further.
A cure exists — the Cure Serum removes the infection, restores the host, and grants a 5-minute immunity window against reinfection.
Risk/reward drops — infected hosts that die past a certain stage have a chance to drop Mutated Tissue, used to craft more Samples or Cure Serums.
Live sidebar HUD — tracks total Infected and Mutated creature counts across the world in real time.
Command support — trigger, cure, or force an outbreak anywhere with simple /scriptevent commands, ideal for testing or admin control.
Items

10
Full Mutation
Solid red. Permanent Strength + Speed, damages nearby uninfected creatures, spreads as aggressively as possible.

Notes for creators
Every tunable number (spread radius, spread chance, outbreak frequency, cure immunity duration, tissue drop rates) lives as a labeled constant at the top of scripts/main.js — easy to retune for a faster, slower, or more punishing outbreak.
