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

The Astral dimension is a broken magical world made up of 10 different biomes. Its peaceful lakes and seas have turned into strange pools of Void Liquid, a substance created by the Void Titan. Walking through this place is risky, so make sure you bring an Elytra.

To enter the Astral dimension, you must construct an Astral Portal. It is similar in shape to a Nether Portal, but composed of at least 10 blocks of Glowing Obsidian. Once built, ignite the portal using Glint and Steel, a handy tool that can also be used later in another dimension.

The dimension is filled with strange lifeforms, from snail‑pig hybrids known as Pigails to odd, fungal beasts called Fatal Shrooms. Players can take on 6 bosses, though only 2 are required to complete the core storyline of the mod.

The first boss you’ll face is the Void Titan. To summon it, it’s highly recommended to head into a Fiery Forest, where large Fiery Mushrooms hide among the trees. Inside these mushrooms are Burning Orbs, which, when shattered, drop Burning Shards.

Combine these shards with 4 Glowstone Dust and an Ender Pearl to craft an Astral Eye.

Throughout your journey, you may come across the Helioos, wandering celestial entities. When you carry both an Astral Eye and a newly discovered item, the Helioos will accept the Eye as an offering. They’ll unveil hidden knowledge about the item you’ve brought before them.

With at least 4 Astral Eyes, you are ready to visit the Amethyst Sanctuary, guarded by 4 Amethyst Knights. These knights are fueled by Postrum Eyes, which can be deactivated using your Astral Eyes. Defeat them to earn 4 Amethyst Keys, used to open Locked Blocks. Inside, you’ll find chests, your goal: collect at least 2 Broken Amethyst Shards.

To proceed, delve deep into the Astral dimension and collect 27 Void Gems to craft 3 Blocks of Void. In the shadows of the underground, beware the Void Mycelium, blocks that spawn Void Menaces. These beasts drop Void Fangs, and you’ll need 4 of them.

With these materials, construct a Void Pillar using 2 Blocks of Void and a single Void Mycelium. From there, you can craft an Astral Altar, requiring 2 Glowing Obsidian, 2 Broken Amethyst Shards, 4 Void Fangs, and a Block of Void. Seek out a Void Egg, a structure featuring a Void Portal. Place the Void Pillar atop the portal, and the Astral Altar upon the Pillar.

Defeating the Void Titan yields a massive amount of Gloomy Obsidian, standard Obsidian, and the Titan Helmet, an item that grants the wearer the Lifesteal effect.
With the Titan defeated, your path leads to the Tormented Mansion, a towering structure rising from the Sludgy Wastelands. It’s the tallest structure in the Astral dimension, and one of the most rewarding.

Inside lies unique loot… and the "final" boss: the Void Visage, source of the Void itself.
Once you slay the Void Titan inside the Void Visage, its shattered remains release Void Shards, Void Gems, and a flood of XP.

Void Shards can be used to craft:
Harsh Leather Armor: grants resistance against Void Liquid
Void Trophy: crafted by combining any sword with 2 Void Shards and a Gloomy Obsidian

Staff of Levitation: a weapon that uses Void Gems as ammo

The Visage also drops the Astral Amulet. This tool allows items to be used in unique, beneficial ways while the player holds a special item in the off‑hand slot. It has a durability of 436 and cannot be stacked.

item image The Void Visage is still active. To truly end it, enter the Setback, a dark realm taken over by the Void that is divided into 6 biomes.
To access it, you’ll need 10 Gloomy Obsidian and a Nanta Star.

Nanta Stars are crafted from 4 Nanta Pearls and a Faded Star.
Find Nantas in pools within Faded Fortresses - feed them Twisted Corals to obtain the Pearls.

Defeat a Slurker to earn a Faded Star.

Activate the portal with your Nanta Star and face the Setback.

Whispers tell of a material hidden here, said to surpass even Netherite. Loot ancient structures to uncover the components needed to upgrade your Netherite gear. With your upgraded gear, you're ready to face the 4 remaining bosses.
