Profundis: Nine New Quality Cave Biomes

Two new released Cave Biomes!

• The Arid Caves generate under hotter areas. They have floors of sand and red sand, with sand in higher levels and red sand below deepslate level. The walls are made up of Terracotta bands of a variety of colours. They generate much like Frozen Caves, but in hotter biomes and rarer.
• The Floral Lush Caves are a variant of Lush Caves. They are exactly identical, except with a floor made of a variety of flowers. Pink Pedals coat the floor, while a mix of all flowers native to the Flower Forest grow in the moss.

Four new Structure Types!

• Cabins generate in every Vanilla and Profundis cave biome, but not in barren caves. They are small to mid-sized bunkers, originally constructed as small bases for miners. They each contain a few functional blocks such as furnaces and crafting tables, plus barrels with loot. The barrels typically have mediocre loot with a pickaxe thrown in, but occasionally contain more valuable treasure. In addition, the loot found in the barrels matches what biome the structure spawns in.
• Ice Dungeons are a variant on regular Monster Room Dungeons that spawn in Frozen Caves. They contain an icy arena with a Skeleton Spawner and 8 pre-spawned Strays (I opted to not use a Stray Spawner as to not contradict with Vanilla's precedent on Strays; if you would like that to change let me know!). They additionally contain four barrels full of typical dungeon loot plus snow and ice.
• Mushroom Houses are an uncommon structure generating beneath Mushroom Fields and in Mushroom Caves. They are non-hostile and contain a few chests of loot, plus some standard utilities. Loot is not very rewarding, but can be a useful source of food in a pinch.
• Amethyst Dungeons are a slightly more difficult version of regular Monster Room Dungeons. They contain one Zombie spawner and one Skeleton spawner, and a Diamond Block in the middle as a reward.

Plus, one minor change:

• Tweaked generation of Frozen Caves and Amethyst Caves: they should be slightly rarer.

This was probably the biggest update to Profundis since I created it! I'm so thankful to all of you for your support, it means so so so much to me! When I started this project I was not expecting such a positive response, so it truly means so much. Thank you all.
