Bubonic
by AvatarKage
Bubonic is a Forge and NeoForge mob mod that brings a plague into the world, where infection spreads from creatures to nearby mobs over the days of a world.
What it does
During world generation, animal mobs occasionally spawn carrying the plague. Infected mobs show black skull particles around them, which warn a player to keep away once the creature is a few blocks off. After dark, zombies are far more likely to appear carrying the infection, which then spreads to mobs close by.
The illness progresses by day. On day 1 the plague is harmless, but from day 2 it starts to kill, and by days 3 and 4 survival becomes almost impossible without treatment. The player dies on day 5 if nothing is done. The mod is described by its author as a simple take on the Black Death, the deadliest pandemic in recorded history, and it is designed for players who want a straightforward survival challenge.
Bubonic runs on client and server, so both the server and every player need it. Files cover game versions 1.19.2 – 1.21.1 across six release versions, and the code is covered by All rights reserved, so the mod is not open source.
Key features
Infected animal spawns
Animals can generate with the plague during world generation, so infected creatures appear in ordinary exploration.
Warning particles
Black skull particles surround infected mobs, giving players a few blocks of warning before they come close.
Night zombie infection
Zombies at night have a far higher chance of spawning infected, and the infection spreads to mobs close by.
Day-based progression
The illness is harmless on day 1, begins to kill on day 2 and is fatal by day 5 unless it is treated.
Cures
An enchanted golden apple cures the infection instantly, and drinking milk also saves the player.
