Hardmode ores are one of the first major progression systems you unlock after defeating the Wall of Flesh. They give you access to stronger Pickaxes, better crafting stations, improved armor, and the equipment you need before taking on the Mechanical Bosses.

The main Hardmode ore progression is split into three tiers:

• Cobalt or Palladium
• Mythril or Orichalcum
• Adamantite or Titanium

Your world randomly gets one ore from each pair.

How to Unlock Hardmode Ores

First, defeat the:

Wall of Flesh

After the fight, you’ll receive a Hammer that can destroy the Altars in your world’s evil biome.

Depending on your world, these will be:

• Demon Altars in Corruption
• Crimson Altars in Crimson

Destroying Altars causes Hardmode ores to generate throughout your world.

Hardmode Ore Tiers

Your world does not get every Hardmode ore naturally.

Instead, it receives one ore from each tier.

Tier 1

Your world gets either:

• Cobalt
• Palladium

Tier 2

Your world gets either:

• Mythril
• Orichalcum

Tier 3

Your world gets either:

• Adamantite
• Titanium

Which ore you receive is randomized.

You don’t manually choose which set appears.

Should You Break Lots of Demon or Crimson Altars?

Breaking more Altars causes more Hardmode ore to generate.

That means:

More Altars = more ore

and:

Fewer Altars = less ore

The tradeoff is that the source warns against breaking too many because of concerns about spreading biome infection throughout the world.

Because of this, you may want to leave some Altars intact rather than destroying every single one you find.

Altars can also still be useful as crafting stations, so keeping a few around can be convenient.

How to Find Hardmode Ores

Once you’ve unlocked them, you’ll need to search underground.

The general progression is:

1. Find Cobalt or Palladium.
2. Make a new Pickaxe.
3. Use it to mine Mythril or Orichalcum.
4. Make another Pickaxe.
5. Use that to mine Adamantite or Titanium.

This mining chain is the main way Hardmode ore progression works.

How to Mine Cobalt or Palladium

The first-tier ore can be mined with:

Molten Pickaxe

The source refers to a requirement of around:

100 Pickaxe Power

Once you’ve collected enough Cobalt or Palladium, craft the corresponding Pickaxe.

That unlocks the next ore tier.

How to Mine Mythril or Orichalcum

You need the first Hardmode Pickaxe to mine:

• Mythril
• Orichalcum

Once you’ve collected enough, make the second-tier Pickaxe.

You should also use these ores to create the next major crafting station:

• Mythril Anvil
• Orichalcum Anvil

This opens access to more Hardmode recipes.

How to Mine Adamantite or Titanium

The third tier requires a Mythril or Orichalcum Pickaxe.

You’ll then be able to mine:

• Adamantite
• Titanium

These are the strongest of the basic Hardmode ore tiers and are generally the main armor ores you want before fighting the Mechanical Bosses.

Where Hardmode Ores Usually Spawn

The source describes the ore tiers as generally appearing at different depths.

Cobalt and Palladium

These can appear relatively high underground.

They’re the easiest Hardmode ores to access first.

Mythril and Orichalcum

These tend to appear deeper than the first tier.

Adamantite and Titanium

These are generally found much deeper underground.

You may have better luck searching closer to:

The Underworld

because the highest-tier ores tend to appear deeper in the world.

Best Armor Before Mechanical Bosses

The source recommends working toward either:

• Adamantite Armor
• Titanium Armor

before seriously taking on the Mechanical Bosses.

You can technically fight them in lower-tier armor, especially if you have strong accessories and good movement, but Adamantite or Titanium gives you a much safer setup.

Is Cobalt Armor Worth Making?

You can craft Cobalt Armor if you want an immediate defensive upgrade.

However, the main priority is usually making:

Cobalt Pickaxe

so you can progress to Mythril or Orichalcum.

Spending too much time and ore on early armor can slow your mining progression.

Palladium Armor

Palladium Armor can be more attractive because it provides a useful healing-related set bonus.

That can make early Hardmode exploration safer while you’re still working toward stronger equipment.

Mythril and Orichalcum Armor

Both are stronger than the first tier and can work as intermediate armor.

However, if you can survive long enough to continue mining, it’s often more efficient to push toward Adamantite or Titanium.

Adamantite vs Titanium

Both are strong early Hardmode armor choices.

The source recommends either one as your main target before fighting the Mechanical Bosses.

Which one you get depends entirely on your world.

You cannot choose whether Adamantite or Titanium naturally generates.

How to Get the Other Hardmode Ore Set

If your world has Cobalt, Mythril, and Adamantite, you may still want:

• Palladium
• Orichalcum
• Titanium

Or vice versa.

The source recommends:

Fishing

Hardmode crates can contain ores from the alternative ore set.

That means you aren’t permanently locked out of ores your world didn’t generate.

Fishing for Hardmode Ores

Fishing can let you obtain Hardmode ores without breaking more Altars.

You’ll want:

• Good Fishing Pole
• Strong bait
• Fishing accessories
• Fishing Potions
• Suitable fishing pools

The downside is time.

Fishing for enough ore to replace regular mining can be much slower than simply smashing Altars and searching underground.

Still, it gives you another option if you want to minimize additional biome spread or obtain an ore your world didn’t naturally receive.

Can You Progress Without Breaking Any Altars?

According to the source, yes.

You can theoretically get your Hardmode ores through:

Fishing crates

instead of relying on Altars.

The downside is that this can take much longer.

You’ll need a strong fishing setup and enough patience to collect large quantities of ore and Bars from crates.

Hardmode Ore Progression Order

The progression path is straightforward:

1. Defeat Wall of Flesh.
2. Use the new Hammer on Demon or Crimson Altars.
3. Unlock Cobalt or Palladium.
4. Mine it with a Molten Pickaxe.
5. Craft Cobalt or Palladium Pickaxe.
6. Mine Mythril or Orichalcum.
7. Craft Mythril or Orichalcum Pickaxe.
8. Craft Mythril or Orichalcum Anvil.
9. Mine Adamantite or Titanium.
10. Craft strong armor.
11. Prepare for Mechanical Bosses.

Hardmode Ore Alternatives

Your world can naturally generate one of two options at every stage.

Tier	Ore Option 1	Ore Option 2
1	Cobalt	Palladium
2	Mythril	Orichalcum
3	Adamantite	Titanium

Getting one does not mean your world is broken or missing content.

That’s simply how the ore system works.

What About Chlorophyte?

The source also mentions:

Chlorophyte

This is a later Hardmode ore connected to the Jungle.

It is not part of the initial three-tier Hardmode mining chain.

The source describes it as becoming more important later in progression, especially after major boss milestones.

You’ll need substantially stronger mining equipment before Chlorophyte becomes part of your progression.

Tips for Finding Hardmode Ores Faster

Search Deep Underground

The higher-tier ores tend to appear deeper.

If you’re looking for Adamantite or Titanium, search near the lower Cavern layer and toward the Underworld.

Upgrade Your Pickaxe Immediately

Don’t delay your mining progression.

The first major goal with each ore tier should be getting the Pickaxe required for the next one.

Don’t Spend Everything on Armor Too Early

You can make armor from the lower tiers, but progression may be faster if you save enough ore for the next Pickaxe first.

Consider Fishing If You Hate Mining

Hardmode crates give you an alternative route.

Fishing is slower, but it can provide ores without requiring you to keep searching through caves.

Leave Some Altars Intact

You don’t necessarily need to destroy every Altar.

Keeping some intact can be useful while still generating enough ore for progression.

Which Hardmode Ore Should You Aim For?

Your main target should be:

Adamantite or Titanium

These are the strongest basic Hardmode ore sets before the Mechanical Bosses.

The earlier ores are mainly stepping stones that give you access to stronger Pickaxes and crafting stations.

A simple priority order is:

Pickaxe first → next ore tier → final armor set

That keeps your progression efficient and avoids wasting large amounts of material on equipment that you’ll replace quickly.

Once you reach Adamantite or Titanium and build your upgraded crafting stations, you’ll have access to the equipment needed to properly prepare for the next stage of Terraria Hardmode: The Destroyer, The Twins, and Skeletron Prime.
