Combatium

(Update: Version 1.9.1 added Sodium Reforged, and should dramatically improve game performance.) Will you chose to venture into sprawling underground dungeons, test your might at defeating powerful dragons, journey through the foreboding Abyss dimension, or build complex structures in the world above? The choice is yours in Combatium, a 1.16.5 medium sized modpack that aims to improve several aspects of vanilla Minecraft. With new dimensions, 100+ unique biomes, hundreds of new building blocks and decor, as well as many new mobs, Combatium is well suited for both modded beginners, and seasoned players looking for a pack on a modern version.
