Advent of Chaos
by dhinozzauro
Advent of Chaos adds a late-game boss fight and its rewards to Forge and NeoForge worlds, and it needs Geckolib to run.
What it does
The mod places new content beyond netherite as an end-game step, centered on a Wither Boss whose heart is used to craft a Wither Nether Star. Geckolib is required, and Curios API is optional. Client and server both need the mod, and the code is under All rights reserved, so it is not open source. Files exist for Forge and NeoForge, covering 1.20.1 and 1.21.4.
Key features
Wither Boss encounter
A Wither Boss fight whose heart serves as the key ingredient for a Wither Nether Star.
End-game progression
New items and gear positioned after netherite, giving a later stage of progression.

Accessory slots can be used when Curios API is installed alongside the mod.
