Upgrade Underground is a lightweight Vanilla+ cave-overhaul mod designed to add more subterranian content. It introduces an new biome, essential underground survival items, deeper progression mechanics, and unique structures to discover while mining.
Lichen Garden A frequent underground biome overflowing with life. Lichen Vegetation: Lichen Sprouts, Tall Lichen Sprouts, and Lichen Mushrooms.
Lichen Wood: Chop down Lichen Trees to gather exclusive Lichen Wood and Lichen Leaves for building.
Glow Lichen Cap: A handy early-game helmet made from a Leather Helmet, a Lichen Mushroom, and 2 Lichen Sprouts. It provides 1 Armor and acts as a portable light source (Level 5 light in a 3x3x3 area).
Lichen Mushrooms: A new cave food source. Cook them to save yourself from eating rotten flesh! They smelt faster, though they provide low saturation.
Gunpowder Bottle: Crafted with 1 Bottle and 1 Gunpowder. Throw it at players to inflict Blindness in a 3x3 radius.
Mud Bricks: Crafted from a Mud Brick Block (yields 4 projectiles). A simple, cheap weapon dealing 3 damage.
Ores & Materials Expansion Anthracite: A rarer, deep-slate tier variant of normal coal. It takes longer to find but smelts 16 items per piece.
Deepslate Expansion: Deepslate Furnace: No stone around? Craft a functional furnace using deepslate blocks just like regular cobblestone.
Deepslate Tools: Craft a new tier of tools sitting perfectly between Stone and Copper in terms of mining speed and power.
Underground Structures Keep your eyes open while exploring. You can now stumble upon two small structures: Pottery Stand: A cozy decorative setup containing a few Decorated Pots, alogside with a few Flower Pots. Lichen Hut: A small abandoned shelter containing starter loot. High chance to find Coal, Torches, Anthracite, Lichen Mushrooms, and even enchanted Deepslate Axes or Pickaxes.
