Naturally Generated Spiderden
Spiderdens contain sculk veins, blocks, deepslate coal ore, cobbled deepslate and webbed deepslate but can be great for easy string, cobweb, and echo shards.
Basalt Delta
Showcasing the Nitre Ore appearing, this ore's texture is only seen from the side, and can be found near lava lakes, but is a great source of fuel and torches within the Nether.
