About this Mod

❓ About
The Deep Aether is an addon for the Aether Mod for Minecraft for 1.19.2 and beyond.
It aims to add lots of new features to give players a chance to venture deeper into the Aether dimension, while also maintaining its original style. Basically, we aim to give the Aether the "1.16 Nether Expansion Update" treatment.
🆕 Features
New Biomes:
- Aerglow Forest
- Blue Aerglow Forest
- Aerlavender Fields
- Yagroot Swamp
- Golden Heights
New Ores, Tools, and Armor:
- Skyjade (found in Holystone; has blocks, armor, tools, and weapons)
- Skyjade's ability is powerful upon first use, but gets weaker the more durability is lost; basically the opposite of Zanite's ability.
- Stratus (found in Sterling Aerclouds, which can be enchanted to Chromatic Aerclouds, and Stratus Ingots can be crafted from them; has blocks, armor, tools, and weapons)
- Stratus's ability is slow falling, an upgrade of Gravitite's ability (high jump), and a dash ability: press R with a full set (including the gloves).
New Trees and Wood Sets:
- Roseroot and Blue Roseroot (Aerglow and Blue Aerglow Forests)
- Yagroot (Yagroot Swamp)
- Cruderoot (Yagroot Swamp)
- Conberry (Golden Heights)
- Sunroot (Golden Heights)
New Mobs:
- Aerglow Fish
- Aether Quail
- Has multiple color variants
New Stone Types:
- Clorite
- Aseterite
New Blocks:
- Aether Mud and Aether Mud Bricks
- Unique grass and path blocks for the Golden Heights biome, as well as the Aether Moss Block for the Yagroot Swamp
- Normal decorative variants for new wood, stone, and ores
- Unique flora for all added biomes, and the Golden Vine Fruit for the Golden Heights biome
- Aerglow Block (crafted from Aerglow Petals, which come from Radiant Orchids and Flowering Roseroot Leaves)
- Virulent Quicksand (functions like how quicksand does in real life, as well as Powdered Snow; immediate suffocation when fallen through)
- Aersmog: A type of Aercloud that is created from the mixture of Water and Poison. Inflicts the Inebration effect when stepped on.
- Sterling and Chromatic Aerclouds
- New variants of Holystone and Mossy Holystone
New Items:
- Golden Grass Seeds (drops from Golden Grass (not the block version); can be crafted with swet balls into a new swet ball type, which can turn Aether Dirt into Golden Grass)
- Music Disks: "Nabooru" and "A Morning Wish" by Emile van Krieken (these tracks were originally meant for the Aether I mod a long time ago, but were never implemented)
New Dungeon Loot:
- Spooky Ring: Increases damage dealt during the nighttime.
New Liquid:
- Poison: It's the normal poison bucket from the Aether I mod, but now you can place it as a liquid (like water), and it naturally spawns in the Yagroot Swamp biome
Mod Cross Compat:
- Aether Lost Content
- Skyjade and Cloudium Shields
- Aether Redux
- Brick and Tile variants for Gilded, Frosted, and Blightmoss Holystone

❓ FAQ
Q: Do you plan on backporting to earlier versions?
- A: No we don't. The Aether I Mod only plans releases from 1.19.2 and onwards, meaning this addon cannot reach versions that are prior to that.
- This also includes future unofficial backports and all the legacy versions: our team only disposes of 2 coders that work on Deep Aether as a hobby, and maintaining older versions with a completely different codebase, while also fixing and updating the newer ones in acceptable timescales would be impossible.
- We have no issues with people that want to backport Deep Aether by themselves, letting us know first, and reminding that the backport is not official nor maintained by us.
Q: Where can I get Sterling Aerclouds? I can't find any!
- A: Sterling Aerclouds are found high up in the Aether skies, above Y = 200. If you're playing with a low render distance it might be harder to spot the clusters, but they're there!
Q: Do you plan on adding cross-compatibility with other mods and Aether addons?
- A: Yes, we have already done that with many of the popular addons: Aether Lost Content, Aether Redux, and more!
Q: I am interested in joining your team to help with the development of the mod! How can I do so?
- A: We are always open to accepting new members, especially testers and developers, as well as translators and modelers! (We are however not in the need of texture artists) | You can join our Discord Server and follow the directions for filling out an application in #recruitment-info! BE PREPARED TO SHOW PROOF OF YOUR SKILLS!
