EthernaWorld
by fayloz
EthernaWorld, a Fabric world generation mod by fayloz, adds new ore types, structures, a magic system and utility machines to Minecraft Java Edition 1.21.8 – 1.21.11.
What it does
Ruby Ore and Amethyst Ore appear in the overworld at heights from Y 0 down to Y -50, while Topaz Ore appears in the End at heights from Y 0 up to Y 60. The author describes the ore set as a new tier of tools and weapons meant to sit below diamond and netherite in strength, so that netherite remains the top material. Crafting new weapons requires smithing table upgrade trims, and the author recommends NEI or JEI for checking recipes.
The mod also adds several multi-block structures to the overworld, a set of decorative and utility blocks, and a magic system whose spells are meant to hit aggressive mobs while leaving passive ones alone. Some spells do not work on certain mobs. The wither and ender dragon fights have been adjusted to be harder, with new rewards for defeating them. Custom mobs are planned for later updates.
EthernaWorld is published only for Fabric, with files for 1.21.8, 1.21.10 and 1.21.11. Servers that run it need every player to install it too. The code is not open source; the mod is released under All rights reserved. The author marks the 1.0 beta line as unfinished, with some planned features not yet implemented.
