Spelunking is cave diving. In Terraria, there is no real game progression without spelunking.
While that may be true, moving the game forward isn’t the only thing digging into the Underground can yield for you. There are treasures, unique building blocks, monsters, and biomes that can only be found in the depths of your maps.
In this Terraria Spelunker Guide, we’ll be giving a comprehensive look at the many layers of the deep below and all its wonders. We want to help you, the gamer, make the most of spelunking in the world of Terraria.
Embark on a boundless adventure in the pixelated sandbox world of Terraria, where you can dig, build, and explore to your heart's content. With endless possibilities for creativity and discovery, join millions of players in crafting your own epic journey.
 A Few Things Up Front
- You cannot dig without a pickaxe or drill.
- It is possible to fall into a hole while digging and die.
- Above ground events, such as a Solar Eclipse or Blood Moon, won’t affect you if you are deep enough underground.
- Most Boss monsters can move through blocks, so going underground won’t protect you from them.
- It gets dark Underground. You will need a light source.
- Pressing SHIFT on a keyboard will let you easily access a torch in your inventory for setting or holding while underground.
 The Underground
The Underground Biome is the first layer of depth below the surface. Some crevices go deep from the surface to the Underground, so paying attention to what monsters are spawning may hint to you that you’ve left the surface.
All of the Underground Biomes contain the following ores.
 Pre-Hardmode
- Â Tin or Copper.
- Lead or Iron.
- Some Silver or Tungsten.
- Rarely Gold or Platinum.
 Hardmode
- Â Palladium or Cobalt ore may appear
- Rarely Mythril or Orichalcum
Any pickaxe will get you through the basic Underground Biome. However, you will find a few more things different as you move through the map. The Underground Biome changes with the surface Biome above it. Here is what you can expect to find in each Underground Biome type.
- Â Forest Underground: Dirt, clay, silt, stone, blinkroot, mice, snails, Green and Teal Mushrooms, Orange Bloodroot, and fairies(rare). You may encounter some traps and treasure chests as well as Underground Cabins. You can also sometimes find gems here in stones and even gem trees.
- Underground Cabins: Cobwebs, looms, chandeliers, wood, wooden walls, wood plank, bookshelves, pianos, treasure chests.
- Treasure Chests: Angel Statue, Band of Regeneration, Cloud in a Bottle, Extractinator, Flare Gun, Hermes Boots, Mace, Magic Mirror, and Shoe Spikes.Â
- Desert Underground: Sand, sandstone, hardened sand, desert fossil, similar Underground Cabins but made with sandstone and often containing an Extractinator in them and a sandstone chest.
- Sandstone Chests: Ancient Chisel, Dunerider Boots, Storm Spear, Thunder Zapper, Magic Conch, Encumbering Stone, Bast Statue, Snake Charmer’s Flute, and a Desert Minecart.
- Corrupted/Crimson/Hallow Desert Underground: The desert biome spreads the evil biomes the fastest and can quickly be overrun by them. The sand and sandstone will become Crimson, Corrupted, or Hallow, depending on which has spread. Unique enemies spawn and will drop Light Shards if it is Hallow and Dark Shards if Corruption or Crimson.Â
- Jungle Underground:Â Mud, stone, clay, vines, jungle grass seeds, Bee Hives, Grubby, Sluggy, Buggy, Jungle Shrines, Underground Cabins(built with mahogany), the Jungle Temple, Life Fruit(after killing a Mechanical Boss), Plantera Bulbs(in Hardmode), Jungle Spores, Moonglow, Sky Blue Flowers and it is possible to get a Jungle Rose or a Nature’s Gift from the vegetation.
- Ivy or Jungle Chests: Anklet of the Wind, Feral Claws, Staff of Regrowth, Fiberglass Fishing Pole, Boomstick, Honey Dispenser, Flower Boots, and Seaweed(rare).
- Boss fight:Â Destroying a Bee Larva in a Bee Hive will summon the Queen Bee!
- Boss fight: Destroying a Plantera Bulb while digging will summon Plantera in Hardmode!(Plantera must be defeated for game progression). Defeating Plantera opens up the Jungle Temple!
- Ice Biome: Ice, snow, slush, Underground Cabins(of Boreal Wood), and Ice Chests.
- Ice Chests: Ice Boomerang, Ice Blade, Ice Skates, Snowball Cannon, Blizzard in a Bottle, Flurry Boots, Ice Mirror, Fish (a pet summoning item), and an Ice Machine.
 Life Crystals can be found in all Underground Biomes but are uncommon.
Keep an eye out for Demon Altars or Crimson Altars underground for special crafting options!
The Caverns
As you dive deeper underground, you enter the Cavern Biome. The enemies get harder and you can find many mini-biomes that give you some of the most flashy building blocks in the game. You also have a higher chance of finding the rare ore from The Underground and more powerful ore.Â
Pre-Hardmode ore you can only locate in The Caverns.
- Demonite ore on a world with Corruption.
- Crimtane ore on a world with Crimson.
- Obsidian, but only where there is lava. (Obsidian can be made by spilling water onto lava anywhere.)
Hardmode ore you can only locate in The Caverns.
- Â Adamantite or Titanium ore.
In Hardmode, Chlorophyte Ore will be throughout the Underground Jungle but can only be mined with a Pickaxe Axe or one of higher quality. For an overview of Pickaxes and how to get them, when to use and the like, click here.
Blocks and general item finds in The Cavern are similar to The Underground, with a few added things to the chests.
 New items in chests: Lucky Horseshow and Lava Charm. (Both of these are great finds!)
The Mini-Biomes
 Here’s a list of the mini-biomes you can find in the Caverns.
- Glowing Mushroom Biome:Â Glowing Mushroom Seeds, Glowing Mushrooms, Glowing Mushroom Chest(will have a Mushroom Vanity Set or Minecart).
- Marble Biome:Â Marble, Smooth Marble, Marble Cabin(with nice Marble furniture), and Marble Chest(has the same treasure as an Underground chest).
- Granite Biome: Granite, Smooth Granite Blocks, Granite Cabin(with cool Granite furniture), and regular Underground Chests.
- Spider Cave Biome: Cobwebs spawn in here over time, so it becomes an infinite source of silk if not destroyed. May have a Web Covered Chest. This chest has ordinary Underground items but always holds a Web Slinger (fun grappling hook). Generates a lot of Spiders.
- Jungle Temple:Â It has Lizhard and Flying Snake enemies(stronger than other Underground base enemies). Find things to summon a solar eclipse here and fight the Golem! Lizhard-based items are found in its chests, pots, or dropped by the enemies.
 Biomes That Spread
 Three types of Biomes can spread and take over the map in Terraria, changing the monsters and terrain. In any map spawn, you will only get one of The Corruption or The Crimson, but in all maps, after defeating the Wall of Flesh, you get The Hallow.
These biomes change the Underground significantly in Hardmode and boast more dangerous threats. They spread as low as the Caverns, stopping only at the Surface and Hell.Â
- Crimson Underground: Deathweed. Usual blocks will become crimson. All enemies here have a chance to drop Soul of Night and Crimson Keys in Hardmode.Â
- Corruption Underground: Deathweed and Vile Mushrooms. Usual blocks will become Corrupt. All enemies here have a chance to drop Soul of Night and Corrupt Keys in Hardmode.
- Hallow Underground: Crystals Shards, Gelatin Crystal(summons Slime Queen!). All enemies here have a chance to drop a Soul of Light, Hallowed Key, or a Blessed Apple(Unicorn Mount!). Usual blocks become Pearlsand.
- Bosses! In both the Crimson and Corruption, you can see some orbs on a wall, emitting a light. Breaking them with a hammer or a bomb will drop many items and put a message on the screen. Breaking three will cause a boss to come. The Brain of Cthulu in a Crimson world. Eater of Worlds in a Corruption world. This is PRE-HARDMODE. It will also drop a meteor onto the surface.
- Shadow Orb Drops(Corruption):Â Musket+ Musket Balls, Shadow Orb, Vilethorn, Ball O’ Hurt and a Band of Starpower.
- Crimson Heart Drops(Crimson): The Undertaker+ Musket Ball, Crimson Heart, Panic Necklace, Crimson Rod and The Rotted Fork.
The Underworld (Hell)
You’ve reached the lowest Biome. There is a lot of lava here. The giant lava lake cannot be turned into Obsidian and breaks the Obsidian can be made anywhere rule. Water dissipates when hitting it.
You can find Underworld Cities here, and you should build a bridge, or you’ll have a lot of trouble fighting the Wall of Flesh. Use whatever blocks you have to make a bridge from one Underworld City to another.
- You can find down here: Shadow Chests, Obsidian Furniture and blocks, Hellstone(ORE!), Fireblossom, Hellforge(needed!), Hellstone bricks, ash blocks, and decorative banners. You can find Hell Butterflies, Lavaflies, and Magma Snails here, but you’ll need a lava net to catch them.
- Shadows Chests:Â You need a shadow key to open, found in the Dungeon. Dark Lance, Sunfury, Flamelash, Flower of Fire, Hellwing Bow, Treasure Magnet, Demonic Hellcart, Ornate Shadow Key, Slice of Hell Cake, and Hellfire Arrows.
- BOSS FIGHT! The Wall of Flesh is fought here.

- The Tortured Soul appears as soon as Hardmode begins.
What about Mimics?
I’m giving them their own spot here because they contain some of the best items you’ll get from an enemy in the game. They all technically count as Mini-Bosses, but you really do need to be wary of Hallow, Corruption, and Crimson Mimics.
Those three are powerhouses even into Mid-Hardmode. They can attack you from far away, will travel through blocks, and don’t be afraid to flee if you aren’t doing well.
Mimics will spawn in Underground Biomes. The normal Mimic has a chance to generate throughout all The Underground Biomes on Hardmode unless you are in an Ice, Hallow, Corruption, or Crimson Biome. See below for items that may drop.
- Mimic: Dual Hook, Magic Dagger, Titan Glove, Philosopher’s Stone, Cross Necklace, Star Cloak, Compass.
- Ice Mimic: Frostbrand, Ice Bow, Toy Sled, Flower of Frost.
- Hallow Mimic: Daedalus Stormbow, Flying Knife, Crystal Vile Shard, Illuminant Hook, Greater Healing Potion, and a Greater Mana Potion.
- Corruption Mimic: Dart Rifle, Worm Hook, Chain Guillotines, Clinger Staff, Putrid Scent, Greater Healing Potion, and a Greater Mana Potion.
- Crimson Mimic: Life Drain, Dart Pistol, Fetid Baghnakhs, Flesh Knuckles, Tendon Hook, Greater Healing Potion, and a Greater Mana Potion.
A Few Important Things!
 NPCs!
- Â In the Spider Cave Biome, you can find: The Stylist
- In the Underground Desert: The Golfer
- After a Goblin Invasion in Cavern Biome: Goblin Tinkerer
- In Hardmode, located in The Cavern: The Wizard
- The Underworld in Hardmode: The Tax Collector(see enemies)
Enchanted Sword Shrine RNG
While spelunking, you may come across an Enchanted Sword Shrine. This will hold one of two swords if it is glowing.
Swords: Enchanted Sword, Terragrim,
The pictures below are of the enchanted sword shrine. The glowing one means you got lucky and will get a sword. Not every world will have an enchanted one. If you are spelunking to find this shrine, make a small map and dig around until you locate a shrine. These shrines usually aren’t far from the surface and often have a little light shining down into them from above. If the 1-3 shines on your small map, don’t have an enchanted one, trash the map and try again.
 Any Tips?
- Â Always upgrade your pickaxe first.
- Having summons around you is an excellent boon while digging.
- There is a lot of good fishing underground. Check here.
- Â Build a two-story house in The Underground. Put The Clothier and Tax Collector with a pet into it. You’ll be able to buy a Cavern Pylon from The Clothier if you do for easy map movement.
- Digging deep without a grappling hook is a bad idea.
- Perching to fight enemies refers to hooking on a high wall and shooting at them with a ranged attack.
 FAQs
Question: Do I need rope when digging?
Answer: No, but it helps a lot in the early game. Sometimes, it can take a while to get a return potion or a magic mirror, and leaving rope to climb up quickens your route home.
Question: Why can’t I mine the ore?
Answer: The level of your pickaxe isn’t strong enough. Check the pickaxe guide suggested in the article.
Question: Do I need to go into The Underground?
Answer: If you want to progress in the game, yes. You 100% need to dig up a bunch of blocks for this.
Question: Can I fight the Wall of Flesh above ground?
Answer: No. It only spawns when a voodoo doll falls in lava. If you do this above ground, it will still generate in the Underworld.
Question: Is the Underground hard?
Answer: Yes. I can recall many times the unique Biome Mimics killed me, not to mention accidentally spawning the Queen Bee early game. She chased me to my nearby bed spawn and killed me for about 17 minutes straight before finally de-spawning. So yeah…it can be a little challenging.
To Summarize
 Spelunking is key to gameplay in Terraria. Many great weapons and item drops are littered in the world below the surface, and game progression is hiding in its depths.
You’ll need the ore, stone, and key items found in the Underground. So, get your pickaxe ready, some torches, a grappling hook, or plenty of rope, and start your descent.
 Good luck and good gaming.
