Astral Dimension

To access the Astral Dimension, you must construct the Astral Portal. It follows the same structure as a Nether Portal, but instead of Obsidian, you need at least 10 Glowing Obsidian. The portal can then be activated using Steel and Dust.

Starting from version 1.5, you will need to install Geckolib to run the mod

The Astral dimension introduces 11 new biomes:

The Lunar Spikes biome consists of Lunar Soil and Moonstone. It generates Moonfoam, Solar Shrub patches in large and small forms, Void Eggs, Lunar Spikes, and Lunar Base Ruins. This biome is home to Ghost Jellyfish and Void Centipedes.

The Pyrite Lunar Fields is a shimmering biome, scattered with Pyrite Blobs, Moonfoam, Postrum Meteorites, Pyrite Crypts, and Solar Nests. Its floor is composed of Lunar Soil and Moonstone. Lurking in the shadows, Void Centipedes roam the biome.

Jelly Glass:

Jelly Glass is a special type of glass, having an unique texture and can be obtained when broken without silk touch. To craft one, first you have to find a Ghost Jellyfish. These mobs spawn in Sludgy Wastelands, Dead Coral Reefs and Lunar Spikes.

They drop Ghost Jelly which is a key item to create Jelly Glass. You will also need 1 Colored Stained Glass.

But that's not all! If you craft or find an Astranite Cauldron, you can apply patterns to these blocks. There are 8 Patterns: Pillar, Present, Flower, Portal, Flake, Metal, Window and Brick. 1 Astranite Cauldron is always present within an Electric Swamp Hut.

This biome is home to Luminous Trees, Fiery Bushes, Lava Wells, Huge Fiery Mushrooms, and Amethyst Sanctuaries. It is inhabited by Magma Cubes, Fiery Hummingbirds, and Fiery Cows, adding both danger and beauty to the environment.

This biome features Fiery Birch Trees, Fiery Bushes, Amethyst Sanctuaries, and Huge Fiery Mushrooms. It is inhabited by Fiery Cows, Fiery Hummingbirds, and Magma Cubes

The Soul Fiery Forest biome is a haunting yet mesmerizing landscape. Its floor is composed of Soul Soil, Soul Blocks, and Smooth Basalt. The biome contains Soul Fiery Trees, Soul Fiery Bushes, Soul Fire Patches, White Pumpkins, and Fossils. Void Centipedes, Torsos, and Ghost Jellyfish mobs spawn here.

At night, Bonefish mobs emerge, drifting through the biome with an eerie presence. The terrain is scattered with dead corals, dead seagrass, dead kelp, and soul blocks, giving the environment a desolate beauty.

The Electric Swamp is a vibrant yet mysterious landscape, featuring Electric Trees, underground Fossils, Huge Void Mushrooms, and Oak Trees. It is inhabited by friendly creatures, including Pigails, Frogs, and the hostile Storm Wisps. The ground is decorated with gravel patches, flowers, electric vines, and various mushrooms.

This biome is a faded variant of Electric Swamps, with a floor composed of Electrified Moss and Lunar Soil. Scattered throughout the terrain, explorers can encounter Faded Spikes, Floating Islands, Faded Temples, and Faded Fortresses. Despite its hostile nature, Pigails and Frogs can still spawn here.

This biome is a dazzling, mystical landscape filled with Amethyst Spikes, Wisteria Trees, and Amethyst Eggs, creating a vibrant atmosphere. Amethyst Crawlers roam the terrain at night. Amethyst Sanctuaries are common structures here, alongside Void Eggs.

Astral Badlands closely resemble regular Badlands, but with distinct tweaks that set them apart. This biome features Dead Bushes, Small cacti, and Fiery Cacti, creating a harsh atmosphere. This is the only biome that features Astral Gold Ore underground. Scattered across its surface, Red Sandstone Towers and Mineshafts naturally generate.

This eerie biome is inhabited by Ghost Jellyfish and Void Centipedes. The landscape is packed with Fossils, Tormented Trees, White Pumpkins, and the massive Tormented Mansions, featuring the final boss, which becomes accessible only after defeating the Void Titan.

Playthrough

First step: Accessing the dimension

The Astral dimension is accessed by entering an Astral portal. The portal is built like the Nether portal, but instead of obsidian, you need at least 10 Glowing Obsidian, and it can be activated with a Steel and Dust. It is recommended to obtain an Elytra before entering the dimension because the void infected every lake.

Second step: Finding a fiery forest

Fiery forests generate huge fiery mushrooms. Huge fiery mushrooms feature burning orbs that drop 1-7 burning shards when broken without silk touch. Burning shards can be used to craft astral eyes.
 

Third step: Going underground

From Y= -12 to Y= -43 void mycelium generates, replacing astral stone. Void ore generates from Y= -12 to Y= -40, and when mined, it drops 1-4 void gems. Make sure to have 27 void gems in your inventory because you will need these to craft 3 block of void. Watch your step; don't step on void magma because it inflicts hunger effect and causes damage while being stepped on, similar to magma blocks. The final thing you need from underground are 4 void fangs. Void fangs are obtained by killing a void menace. Void menace mobs spawn on top of void mycelium, and these beasts drop 0–2 void fang items. I recommend crafting a bow, full iron armor, iron tools and a shield because a void menace is pretty tough. It has 50 HP, deals 8 melee damage, and creates void spikes on the void mycelium.

Fourth step: Defeating an Amethyst Sanctuary

Amethyst sanctuaries generate in fiery forests, amethyst meadows and dead coral reefs. Two amethyst knights inhabit this structure, and you need to deactivate 4 postrum eyes because the knights start taking 20 damage when there isn't a postrum eye within a 400-block radius. Craft at least 4 astral eyes because these items deactivate the postrum eyes. Amethyst knights have 600 HP, are hostile to players; they deal 22 melee damage and they summon amethyst sentries when they get hurt. Amethyst sentries are flying hostile mobs that shoot fireballs, so it is recommended to brew fire resistance potions when raiding this structure. Amethyst knights drop 2 amethyst keys and 0-1 amethyst helmet. Using amethyst keys, the player can unlock the four locked chests in the dungeon. These chests contain broken amethyst shards. You will need at least 2 broken amethyst shards to summon the Void Titan, the first boss of the mod.

Fifth step: Summoning the Void Titan

To summon it, first you have to locate a Void Egg. These structures can be found rarely in amethyst meadows, lunar spikes and astral badlands. Every void egg contains a Void Portal on top of it. Place a void pillar above the portal, then place an Astral Altar on top of the pillar. After you place the altar, the Void Titan will appear with a huge explosion very soon... The void titan has 360 HP. Stay distant from the titan because it shoots exploding projectiles at you. It can also spawn void worms and firestorms.

The Void Titan:
-Boss mob
-Spawned by an Astral Altar
-Has 4 Attacks:
   -Void Charge: Shoots a projectile that explodes on impact.
   -Void Golems: A fyling hostile mob that attacks the player. Spawns an exploding Mine when it dies.
   -Void Worm Eggs: When they hatch Void Worms are spawned.
-Drops Gloomy Obsidian, Titan Helmet, Obsidian and Void gems.

Using 10 gloomy obsidians, the player can construct a portal frame. This portal can be activated using a Nanta Star.

To craft a nanta star, you need to locate a faded electric swamp. There, you will notice some floating islands that contain twisted corals.

Once you have collected some twisted corals, locate a flooded faded fortress—a rare, faded fortress variant that generates in faded electric swamps. These structures are inhabited by slurkers; make sure to kill at least one of them.

Nantas also spawn here underwater. If you feed them twisted corals, they will sometimes give you a nanta pearl. Collect 4 nanta pearls and a faded star (obtained by killing a slurker) to craft the star. Once you have a nanta star, you are ready to visit the Setback.

The Setback:

-A dark dimension that has been taken over by void
-Accessible after defeating the Void Titan
-Bedrock generates at Y=32 and the build limit is Y=320
-The bottom of the dimension is sometimes destroyed, allowing the player to gaze into the void
-Natural sources of light include void mushrooms and void liquid
-Void liquid is the most common fluid that naturally generates abundantly in this dimension
in the form of deltas, rivers, lakes and oceans
-Harsh Stone makes up most of the Setback's terrain
-Features 4 new biomes: Sick Woods, Frozen Harsh Barrens, Frozen Postrum Reef and Void Postrum Reef

Final step: Defeating the Tormented Mansion

After you defeat the Void Titan, take a visit to the Tormented Mansion. These mansions rarely generate in sludgy wastelands. This place is inhabited by keepers and tormented guards, both melee mobs. In the upper part of the structure, you can find the Locked Visage, surrounded by titan sentries and void crystals. Once you defeat the crystals, the player can attack the Locked Visage. When you defeat the Locked Visage the real battle begins. The Void Visage appears, summoning an Overworld Visage Portal and a Nether Visage Portal. These portals summon mobs from the Overworld and Nether dimension. When you defeat the Void Visage, the connection between the End and the Astral dimension will be broken, and soon the dimension can begin to recover from the End's evil magic and the void corruption.

Faded Fortress:

Faded fortresses are floating structures generating in Faded Islands biomes.

The structure is inhabited by Slurkers.

6 Shade Chests can be found here each containing some pretty cool loot.

Blooming Dread blocks can be found in these chests.

These can be used to grow 3 seeds found in structures across the Astral dimension.

Lava Wells contain Red Chilli Seeds:

Red Chilli seeds are used to grow Red Chilli that when eaten, inflict Fire Trail effect.

Tormented Mansions contain Ghoulish Seeds:

Ghoulish seeds are used to grow Saturation Berries that when eaten, inflict Saturation and Weakness effect.

Lunar Base Ruins contain Lunar Beetroot Seeds:

Lunar Beetroot Seeds are used to grow Lunar Beetroots that when eaten highlights nearby mobs with glowing effect.

You can also bake some fancy cakes using these magical crops. These have 5 slices, each slice restores 2 hunger and applies potion effects.
