About
ReNether is a second Nether update, aiming to expand the Nether with a little bit of everything- biomes, mobs, resources, treasures, structures, potions, all sorts of things.
It's mostly vanilla-style, and doesn't add anything super groundbreaking- just a bit of extra life and variety.
Explore new variants of old biomes, new biomes entirely, delve into the Catacombs and fight the Damned, put on some Strider Boots to run across lava lakes, and experiment with redstone signal strength using new Lead components.
