Adventure Catalyst
Adventure Catalyst is a Fabric mod for Minecraft 1.20.1 that adds two new cave biomes, six mobs, armor upgrades and a non-linear progression path.
What it does
Two new cave biomes, Preservation Basins and Sunken Swamp, sit deep underground. Preservation Basins fill with amber over time, and a small insect lives in the amber sections. Sunken Swamp holds large bodies of water under the cave floor, where flora grows despite the lack of sunlight. Players can swim through the lakes to find rare Nymph Lotus and Moatstool, or search for other routes around them.
The mod adds six mobs spread across its new biomes, 38 blocks for building and decorating, and 28 items including 10 consumables with unique effects. Armor upgrades can be combined to build different gear sets, and they work with golden armor and the Adventure Gear mod to open more equipment options. A new Subterranean difficulty stops mineshaft-style spawning from reaching the surface, and the mod is built to support movement-based playstyles.
Adventure Catalyst needs Fabric API on Fabric. It runs on the client and the server, so both sides need it, and it is published only for Fabric with 1.0.5 for 1.20.1 as the latest file, under All rights reserved. The mod is not open source.
