The Thorium Mod adds one new biome to the game, along with several additions to existing vanilla biomes.
The Aquatic Depths is an underground biome completely filled with water. It is found underneath the ocean biome's sandy floor, opposite of the dungeon. The player can enter the Aquatic Depths through a huge gap in the sand.
The biome features its own unique tiles, backdrops, enemies, loot and music. Certain ambient objects found in the biome can be broken to release bubbles that briefly allow players that touch them to breathe underwater. Platforms that elevate Depth Chests can randomly be found within the pockets of open water within the biome; they contain their own assortment of unique loot.
In addition to containing many veins of Mossy Gold or Mossy Platinum Ore, the Aquatic Depths also contains a unique ore, Aquaite, and a unique gem, Pearls, that are both used in several water-related items. It also contains pockets of Brackish Clumps, which can be extractinated similarly to Silt and Slush.
While in the Aquatic Depths, players will receive a Choking Aura debuff, which makes them lose health over time if they are exposed to air. This debuff will be replaced with the Untainted Waters buff if Abyssion, The Forgotten One has been defeated at least once in that world, making the waters of the biome breathable and the air non-toxic.
