Ashfall
by sam021800
Ashfall changes cave generation on NeoForge, with over 200 new blocks, a renewable source of resources from geodes, and an underground village.
What it does
Ashfall reshapes underground areas with new cave decorations and generation tools. Over 200 blocks come with the mod, and 14 of those are stone varieties that appear in caves without any crafting, with cobwebs, crystals, skeleton remains, rocksalt, scribed stone, plants and speleothems also included. Many of the blocks carry hidden features. Geodes give a renewable route to resources, and a new underground structure holds a mining villager who offers unique trades. Ashfall runs on NeoForge for 1.21.1 – 1.21.5 and needs to be installed on both the client and the server. It is closed source under All rights reserved.
