Born in Chaos
Players who explore caves and nights in Born in Chaos meet a set of new aggressive mobs, each with its own threat level, plus a boss, weapons, armor and structures.
What it does
The mod adds many aggressive mobs grouped into undead, spirits, arthropods and a few without a special type. Each spawns in set biome types, so the mobs appear only where the mod places them. Decrepit Skeleton is a weak melee-only enemy, while Exploding Skeleton detonates at low health and stops moving, leaving a short window to finish it or run.
Other mobs add pressure in different ways. A zombie stuck in a barrel near water does not drown, resists the sun and carries heavier armor, and a zombie that loses its flesh turns into a Decrepit Skeleton. Game rules, set before world creation or with /gamerule, can disable mobs and structures. Configuration options are available for the same purpose.
Installation requires GeckoLib on both Forge and NeoForge. Born in Chaos is client and server, so the server and every player need it. Files are published for Forge and NeoForge across 1.20.1 and 1.21.1, and the mod is released under All rights reserved, so it is not open source.
