more underground structures
by tombkingsts
Underground, the mod adds small structures to the overworld, including chest dungeons, spawner rooms, shrines, wells and ore veins, so mining trips turn up more than stone.
What it does
Most of the generated content sits below ground. Chest dungeons hold loot and some carry traps, while spawner dungeons hold zombie, silverfish or drowned spawners, and stray and husk variants appear in cold biomes and deserts. Small shrines built from stone bricks or nether bricks, underground wells holding a little water, and fake end portal rooms with a bed are also placed in the world. Some structures are left abandoned and draped in cobwebs, and smaller or larger versions exist.
Structures can also appear above ground, floating in the air or over an ocean, and ice spikes and obsidian spikes are placed in cold biomes and beside lava. Ore veins take new shapes and carry iron, gold, coal or magma blocks, with andesite or snow blocks mixed in. The mod is built for Forge and NeoForge, and it runs on client and server, so both the server and every player need it. Released under the MIT License, it is not open source.
