Deep Aether: Expanding the Aether Dimension
Deep Aether is an addon for The Aether that gives the sky dimension a major content expansion in its original style. This guide covers what it adds.
New biomes
Deep Aether aims to give the Aether a Nether-Update-style expansion, adding new biomes to venture into: the Aerglow Forest and Blue Aerglow Forest, the Aerlavender Fields, the Yagroot Swamp and the Golden Heights. Each brings its own scenery, blocks and creatures to a dimension that was previously more uniform.
Skyjade and new gear
The standout material is Skyjade, found in Holystone, with its own blocks, armor, tools and weapons. Skyjade's ability is unusual: it is powerful on first use but grows weaker as durability is lost — the opposite of normal wear — so it rewards fresh, well-maintained gear.
Getting started
Deep Aether requires The Aether, so set up the base mod first, then explore the new biomes for Skyjade and the addon's other ores, tools and armor. Treat it as a reason to venture deeper into the Aether, filling out the dimension with fresh regions, materials and challenges in the Aether's own aesthetic.
Where the recipes are
Deep Aether is 376 pages across 253 blocks and 123 items, and the recipe list is spread across eleven categories:
- Crafting — 193 on 1.21.1, 196 on 1.20.1
- Stonecutting — 104 and 83
- Repairing — 20 on both
- Smithing Transform — 18 on both
- Poison Recipe — 13 and 8
- Enchanting — 11 and 7
- Smelting — 5, Combining — 4, Smoking — 2, Blasting and Freezing — 1 each
Repairing at 20 recipes is the one to notice early. Aether gear does not mend the way overworld gear does, and this category is why — repairs are their own recipes rather than an anvil operation.
Four structures, and they cluster
The mod generates Altar Camp, Campfire and Combiner Corridor on a spacing of 8 with a separation of 3 — very dense, so they turn up constantly — and the Brass Dungeon on a spacing of 20 with a separation of 12, which is the rare one worth travelling for.
That spread tells you how to play the dimension: the small camps are ambient and constant, the dungeon is the destination.
Stonecutting grew, crafting did not
Between versions crafting fell slightly (196 to 193) while stonecutting rose from 83 to 104. Block variants moved to the cutter, so on 1.21.1 the stonecutter is the faster route to building material.
Combining and freezing
Both are single-digit categories — 4 and 1 recipe — but they are Aether-specific machines rather than vanilla ones, so their handful of recipes are the mod's distinctive processing steps.
