The UndergardenUnderground purple-mushroom dimension — Forgotten Battlefield, Rotspine Forest, Smogstem Lowlands
About
An underground biome dimension. Build a Catalyst portal (Catalyst block from a Depthrock + Cloggrum recipe) → enter the Undergarden. Purple haze, glowing fungi, twisted plants. Unique ores (Cloggrum, Froststeel, Forgotten Armor materials). Mobs (Rotbeasts, Brute, Underminer). Mid-difficulty exploration dimension with a distinctive aesthetic — not as boss-heavy as Twilight Forest, but rich in materials.
Things to do
- Build the Catalyst portal (Depthrock + Cloggrum required)
- Mine Cloggrum + Froststeel for Forgotten weapons/armor
- Explore Smogstem Lowlands biome
- Beat the Forgotten Guardian boss
Getting started
JEI shows portal recipe. Need a pickaxe at iron+ to mine Depthrock.
