Optifine/Optifabric will not work with this modpack.
This is my first modpack. Hope you like it there's lots of origins too pick from. I don't know exactly how many origins there are I think there are 15+. There is a vein mining mod, mini map mod also. The origins mod effectcts on your in game experience will vary depending on which origin you chose some of them are being tiny, climbing walls, breathing under water but not being able to on land, spawning in the Nether, fire immunity. There are no biomes added, but there are a few creative items added, ore variants for diorite, andesite etc. and plenty of decoration blocks.
