Hec's Extensions
by Hec1
Hec's Extensions is a NeoForge mod for Minecraft 1.21.8 that fills gaps the vanilla game left unfinished, with chainmail armor, a rotten golden apple, a structure and a sniffer change.
What it does
Chainmail armor is crafted from leather and iron chains and sits between leather and iron as a side-grade. Each chainmail piece gives the wearer a chance to deflect an incoming arrow entirely, instead of only reducing its damage by half. Amethyst-linked armor can be upgraded further with amethyst drops.
Hec's Extensions also adds an Abandoned Stable structure, which holds a skeleton horse with a tragic backstory, and a Rotten Golden Apple made from a golden apple and rotten flesh. The apple gives an effect that depends on the time of day, either Undead Skin or Insatiable Fury, and feeding it to a skeleton horse grants speed and maximum health regeneration. The sniffer receives a torchflower-related change that is purely cosmetic.
The mod is one of several general content additions on NeoForge for 1.21.8 and runs on client and server, so the server and every player need it. Files are published only for NeoForge 1.21.8, released on 2026-03-31 as version 1.0.0, under All rights reserved, which means the mod is not open source.
Key features
