Myrix Mod

by carmifele

Myrix Mod is an exploration-based fantasy mod for NeoForge that adds Swamp Wyverns, armor made from their scales, and acid-based items.

What it does

The mod is meant to fill gaps in larger modpacks by giving players a fantasy layer to find while exploring. Swamp Wyverns are medium-sized predators that live in swamps. They feed mostly on other animals, hunt them down, spray acid and bite, and they will attack a human who comes too close.

Wyvern acid is strong enough to melt through armor, removing chunks of durability with each hit. Once the armor is gone, acid begins to damage health instead. Players can avoid this with Anti-Acid, an item that makes armor immune to acid, found through enchanting tables, loot and villagers. Slaying enough Wyverns allows crafting Wyvern Scale armor, which resists acid better than iron. Wyverns also drop guts, which a brewing stand turns into acid potions, and adding gunpowder lets players throw acid at enemies.

Abandoned Farmhouses are scattered through flatter biomes and can be found while travelling. They hold edible food and some old tools, and they attract rats. Myrix Mod is published for NeoForge only, for Minecraft 1.21.1, with the latest file at 1.1.1. The server and every player need the mod installed. The code is released under the MIT License, and the mod is not open source.

How it compares

Full comparison

Lex's Dragons is a NeoForge mod for 1.21.1 with a client and server environment, under All rights reserved and not open source, so it focuses on dragons rather than swamp predators. Create: Made Easy is a NeoForge mod for 1.21.1 that also runs on client and server, under the MIT License and not open source, and it simplifies Create machinery rather than adding mobs. Deepborn is a NeoForge mod with files for 1.21.4 – 1.21.10, under the MIT License and not open source, so it does not cover the 1.21.1 version that Myrix Mod targets.

What the author says

Hello everyone, and welcome to the Myrix mod! This is a project I've had in the works for a while now, and I believe I'm at the point of doing a first release of the mod. It's something I'm still working on, of course, but I'm happy enough with my progress to publish it, for now.
