This modpack adds new biomes and world gen, many new structures and dungeons, makes pillagers and the undead a real challenge, adds the ability to build new tech contraptions with mods such as Create and Immersive Engineering, an variety of magic mods, and tons of quality of life improvements.
Will take a lot of configuration, may be buggy. Optifine can NOT be used with this modpack, it is incompatible with many of the mods. Embeddium and oculus are included for shader support.
JER fails to work at the moment due to a mod conflict. For server use you must remove client sided mods or it will fail to start.
Recommended JVM arguments for better performance, I noticed an improvement, ymmv. Copy the text to your minecraft installation settings and/or in your curseforge app under minecraft/java settings/additional arguments.
