Toxony
by MrFrostyDev
Toxony is a NeoForge magic mod about poisons, toxins, oils and mutagens, with weapons and armour built around them for players who hunt monsters.
What it does
Toxony centres on a toxin system that tracks how toxic a character becomes. Players gather new plants and special materials, then use blocks to create special items. Oils can be applied to weapons, and the mod also includes an alternative form of Netherite that can be obtained in the overworld. The theme draws on old chemistry and potion mechanics, loosely inspired by the Witcher 3, and the mod is described by its author as being in beta with possible bugs.
Mutagens give semi-permanent buffs to the character, so the effects of toxin handling carry between play sessions. Several special structures and plants can be found in the world, and some decorations are themed after copper alchemy. A Lost Journal serves as the starting guide, and the author text recommends reading it before crafting. The mod is released under the GNU Lesser General Public License v3.0 only and is open source, with source code published. It runs on the client and the server, so both need it, and it is built for NeoForge 1.21.1 only, with the latest file 0.10.7 released on 2026-06-12 on the beta channel.

"For a moment. I felt fresh air hug me tightly around my empty arms and legs. The brief respite of calm from the wind and the daisies around me. I felt alive again, free from everthing. The pain, the misery, washed away for a little while. But only a little. Until I feel the poison flow through my veins again. As the…
