Taming the Cosmos: A Comprehensive Guide to Mining Astral Ore in Terraria Calamity

So, you’re ready to delve into the shimmering, otherworldly depths of the Astral Infection and extract the coveted Astral Ore? Good! It’s a vital step in progressing through the Calamity Mod, granting access to powerful armor and weapons. But the astral realm doesn’t yield its treasures easily. Let’s get you prepared.

How do you mine Astral Ore?

You can’t just waltz in with any old pickaxe. First and foremost, you must defeat Astrum Deus. This cosmic serpent is the key to unlocking the ore’s mineability. After that colossal battle, you’ll need a pickaxe (or drill) with at least 210% pickaxe power. Think of it as flexing your mining muscles! Once you meet these requirements, you can swing away at those beautiful, glittering deposits. Note: the Crystyl Crusher’s beam can destroy Astral Ore before Astrum Deus is defeated.

Understanding the Astral Infection

Before we go any further, let’s get familiar with the environment we’ll be working in. The Astral Infection is a unique, Hardmode biome that brings a touch of the cosmos down to Terraria.

Origin and Spread

The infection begins with an Astral Meteor landing after the Wall of Flesh is defeated. Don’t expect it to spread like the Corruption or Hallow, though. Only the meteor’s initial impact will infect nearby tiles. If you want to expand the biome, you’ll need the Clentaminator and Astral Solution, sold by the Steampunker when she’s residing in the biome.

Key Components

Astral Monolith: This block replaces wood in the Astral Infection and is obtained by cutting down trees (now Monoliths!). It’s essential for crafting Titan Heart armor.
Astral Slimes: These gooey creatures become a source of Astral Ore after defeating Astrum Deus. A welcome bonus!
Astral Crate: Fishing in the Astral Infection can yield these crates, which contain Astral Bars (the refined form of the ore) after you’ve defeated Astrum Deus. A great way to bypass mining altogether if fishing is more your speed.
Astral Beacon: A furniture item found naturally or crafted, used to summon Astrum Deus during the night (with a Titan Heart or Starcore in your inventory).

Preparing for the Mine

Now that you know what to expect from the biome, let’s prep for the excavation.

Essential Tools

As mentioned before, you’ll need a pickaxe with at least 210% pickaxe power. Here are a few options:

Picksaw (or a pickaxe of a higher power): A high-powered pickaxe.
Drills that meet or exceed the pickaxe power requirement.

Survivability

The Astral Infection isn’t exactly a walk in the park. Here are some hazards to consider:

Astral Infection Debuff: This debuff damages you over time and reduces your damage output. Equip the Ursa Sergeant or Hide of Astrum Deus accessories for immunity.
Enemies: Prepare for tough enemies!
