❓ 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!
