This article is about the world mode. For the player character mode, see Hardcore.
Initial Hardmode map of a small PC-version world. Notice the "V" made of the new outburst of Corruption (dark purple) and Hallow (pale pink) biomes, which each replace existing world blocks upon defeat of the Wall of Flesh.

"The ancient spirits of light and dark have been released."

Hardmode is a harder version of the initial world. A world permanently converts to Hardmode after the player defeats the Wall of Flesh in that world.

Hardmode contains new Biomes called the Underground Corruption/Underground Crimson and The Hallow (along with the Underground Hallow). Corruption/Crimson and Hallow both spread continuously in Hardmode, and can eventually overtake an entire Map.

Demon Altars/Crimson Altars become breakable with the Pwnhammer (which drops from the Wall of Flesh), and upon doing so, new Ores become available. Along with all regular enemies, Hardmode contains new enemies that are more difficult, some of which are "upgraded" versions of regular-mode enemies. In addition, coin drops and item prices both rise.

Hardmode also makes new Armors, Weapons, Accessories, and other items available that will help, and are sometimes essential, in dealing with new Hardmode challenges. Some of these become available for purchase from NPCs, as drops from enemies, or are craftable using new Hardmode materials and crafting stations.

Defeating the Wall of Flesh triggers the announcement, "The ancient spirits of light and dark have been released." Immediately, two diagonal stripes of the new biomes generate, replacing large sections of the World in a "V" pattern that extends from the center of The Underworld all the way to the surface.

Underground Corruption and Crimson primarily replace stone, sand, ice and snow. Underground Jungle biomes do not generally contain these in significant amounts, and so are not replaced (though the Underground Jungle does have its own new Hardmode entities). The mud in an Underground Jungle will slowly be converted upon contact with the Underground Corruption or Crimson.

The Underground Corruption/Crimson looks similar to the surface Corruption/Crimson, though containing several new Corruption/Crimson-themed enemies.

The Hallow represents a brand-new theme, distinguished by its pastel-colored fairytale imagery. Rainbows make up the surface's background image, its trees are puffy and multicolored, and enemies look similarly whimsical, such as the Unicorn and Pixie. Do not be fooled, though: Hallow enemies are quick, resilient, and deadly, and their spawn rates are high.


The Corruption/Crimson and Hallow spread actively in Hardmode:

  • Corruption, Crimson and Hallow will spread to stone, sand, ice and grass that are up to three tiles away.
  • Almost all other blocks are immune to Corruption/Crimson and Hallow.
  • Mud will slow the spread of Corruption and Crimson, but not stop it, since Corruption and Crimson can convert mud blocks into dirt over time. Mud blocks containing mushroom grass are not affected. Hallow cannot convert mud at all.
  • Hallow and Corruption/Crimson cannot convert each other.
  • Also in the mobile version if you put a sunflower next to the Corruption/Hallow it will not spread.

These new properties mean that Hallow and Corruption/Crimson will now continuously spread, and can reach your home base, given enough time. It is advisable to take steps to protect any areas you want to invest time in keeping around, which can be done by mining away a four-tile-wide frame surrounding the area, then sealing it in with Wood or Clay. A Sky City is another option.


The Wall of Flesh always drops the Pwnhammer upon its defeat, which can be used to destroy Demon/Crimson Altars (note that bringing the Pwnhammer to a regular-mode world will not allow you to destroy Demon Altars there). The first three Demon Altars destroyed will trigger the creation of three new Ores, in the following order:

For every Demon Altar you break, 1-3 Wraiths will spawn immediately. The new ores are created by replacing existing World blocks.

Subsequent Demon Altars destroyed will begin the cycle again, though the fourth to sixth altars will drop half as much ore as the first ones, the seventh to ninth will drop only one third of the ore of the first ones, and so forth. This "multiplier" can be calculated with the formula 1/(ceiling(n/3) + 1 - sgn(n)) where n is the number of altars destroyed. So, destroying the 19th altar would yield one-seventh of Cobalt Ore or Palladium Ore compared to the first altar.

Each time a Demon Altar is destroyed, there is also a chance that a single random tile of rock in the world will be converted into ebonstone/crimstone or pearlstone, which will likely grow to become a new underground Hallow or Corruption/Crimson given enough time.

No matter how many Altars are destroyed, Ore rarity remains set with Cobalt/Palladium being the most common, followed by Mythril/Orichalcum, then Adamantite/Titanium as the most rare.

Mining and crafting[edit]


  • Pc only.png Duke Fishron is a horrid pig-fish-dragon hybrid found in the Ocean. He is summoned using Truffle Worms which only spawn in the mushroom biome during Hardmode.

The three Mechanical Bosses are more difficult "upgraded" versions of the regular-mode bosses, and are summoned via new craftable items:

After the mechanical bosses above are defeated, Plantera becomes available for summoning:

After Plantera is defeated and a Temple Key is collected from it, the Golem becomes available:

All pre-Hardmode bosses can still be summoned in Hardmode.


Once Plantera is defeated, the world undergoes a second minor transformation:

  • New enemy types begin spawning in the Dungeon, which are even harder than ordinary Hardmode enemies. See Dungeon for the list of post-Plantera enemies.
  • The spread of the Hallow, Corruption, and Crimson is slowed.
  • The Cyborg NPC becomes available.
  • The Truffle NPC begins selling the Autohammer, which crafts Shroomite Bars.

As secondary effects, a post-Plantera world offers access to the following:


Angler Fish.png Angler Fish • Armored Skeleton.png Armored Skeleton • Black Recluse.png Black Recluse • Chaos Elemental.png Chaos Elemental • Clinger.png Clinger • Clown.png Clown • Corruptor.png Corruptor • Cursed Hammer.png Cursed Hammer • Digger.png Digger • Enchanted Sword (NPC).png Enchanted Sword (NPC) • Gastropod.png Gastropod • Giant Bat.png Giant Bat • Green Jellyfish.png Green Jellyfish • Illuminant Bat.png Illuminant Bat • Illuminant Slime.png Illuminant Slime • Mimic.png Mimic • Mummy.png Mummy • Pigron.png Pigron • Pixie.png Pixie • Possessed Armor.png Possessed Armor • Skeleton Archer.png Skeleton Archer • Slimer.png Slimer • Toxic Sludge.png Toxic Sludge • Unicorn.png Unicorn • Wandering Eye.png Wandering Eye • Werewolf.png Werewolf • World Feeder.png World Feeder • Wraith.png Wraith • Wyvern.png Wyvern • Derpling.png Derpling

See The Hallow, Underground Hallow, Corruption, Underground Corruption,Crimson, and Underground Crimson for lists of enemies that spawn in those biomes during Hardmode.

Most of these enemies are significantly harder, doing more damage and having higher health and defense than pre-Hardmode enemies. Most Pre-Hardmode weapons can prove ineffective, and until a player can obtain new Hardmode gear, they may be forced to avoid enemy swarms and/or play more strategically.


Several new NPCs become available in Hardmode

  • The Wizard can be found in nearly any open area underground, initially bound, and speaking to him frees him (similar to the Mechanic and the Goblin Tinkerer). He will then respawn as long as a vacant House is available. The Wizard sells magic-related items.
  • Santa Claus appears between December 15th and 31st (based on your computer's time setting), after the defeat of the Frost Legion, so long as a vacant House is available. He sells the Santa costume, Red/Green/Blue lights, the Christmas Tree, and decorations for it.
  • The Steampunker appears after defeating one Mechanical Boss, and if a vacant House is available. She sells Teleporters and other steampunk items.
  • The Truffle appears once you make a house in a mushroom biome above ground when your world is in hardmode. He sells useful mushroom themed items and the Autohammer.
  • The Cyborg appears once you have defeated Plantera, so long as a vacant house is available. He sells rockets and other mechanical items. At night he sells more advanced items such as upgraded rockets.
  • The Pirate appears once you have defeated a Pirate Invasion, and sells a vanity set as well as other pirate themed items.


There are several new events in Hardmode:

  • The Frost Legion is triggered by the Snow Globe and never invades on its own. The Snow Globe can be used to summon the Frost Legion in non-Hardmode worlds, but the Snow Globe itself can only be acquired from Presents in a Hardmode world.
  • Pirate Invasions are triggered by the Pirate Map, or can appear randomly at the start of the day.
  • Solar Eclipses behave like the Blood Moon, only during the day, and can appear after any Hardmode boss is defeated. During a Solar Eclipse, unique and powerful monsters will spawn in vast numbers, including Reapers, Vampires, Swamp Things, Frankensteins and Eyezors.
  • The Pumpkin Moon is the one of the most challenging Hardmode events. It can only be started at night by the player using a Pumpkin Moon Medallion, which is crafted with 30 Pumpkins, 5 Ectoplasm, and 10 Hallowed Bars. This turns the moon into a scary pumpkin face. The event has 15 waves, with each wave requiring a progressively higher score to progress to the next. Enemies that spawn are Scarecrows, Splinterlings, Hellhounds, Poltergeists, Headless Horseman, a mini-boss Mourning Wood, and a boss Pumpking. More and harder enemies will spawn at higher waves, and there can be several Mourning Woods and Pumpkings attacking at once. The event ends at the end of the night or when all 15 waves have been completed.
  • Pc only.png Console only.png The Frost Moon is an invasion-like event similar to the Pumpkin Moon, though being a step up on the difficulty. It is started by using the Naughty Present at night. Featuring some of the game's strongest enemies and 20 waves, it is currently the most difficult encounter in Terraria.

In Hardmode worlds, Goblin Armies do still invade, and Meteorites still land, each at their regular rates. Blood Moons and Rain also occur just as frequently, though with new Hardmode enemies.


Several new Tools, Weapons, Accessories, Armors, and crafting materials become available in Hardmode, as enemy drops, sold from NPCs, or via crafting. Drills, Chainsaws, and Repeaters are variations of Pickaxes, Axes, and Bows, respectively, which can be obtained once in Hardmode.


Each of the many hardmode Ores have their own complete item set, including Armor, Drill, Chainsaw, Sword, Spear, and Repeater. In addition, Hallowed Armor and associated tools and weapons become available: the Drax, Excalibur, Gungnir, and Hallowed Repeater. Crafting Hallow-tier items required creating the item sets for what was then all the hardmode ores and defeating the Mechanical Bosses introduced with hardmode for set-specific boss souls. As of 1.2, their crafting recipes were simplified to need only Hallowed Bars, which dropped when the mechanical bosses were killed.

Many of the hardmode Armor sets have three different options for the Helmet slot, which each benefit players that use either Magic Weapons, Melee Weapons, or Ranged Weapons. Shroomite Armor is an exception - its helmet choices benefit ranged weapons in all cases, although only specific ones (see the article for details).

Magic weapons[edit]

New Magic Weapons that are obtainable or craftable after merely traversing the new Underground biomes for a reasonable amount of time include:

After killing The Twins, the following become craftable:

Crafting materials[edit]

Six different types of Souls are a common requirement for crafting many Hardmode items, and are dropped from various sources.

In addition, the following common materials are used for consumables:

Note: See The Hallow, Underground Hallow, Corruption, Underground Corruption, Crimson, and Underground Crimson for complete item drop lists.



Corruption and Hallow spread[edit]

  • If you've built a Corruption farm near your Town to farm Vile Mushrooms, or a corrupted Arena to farm the Eater of Worlds, you will want to either demolish them completely or seal them completely with Wood before defeating the Wall of Flesh. Corruption spreads very quickly and easily in Hardmode, including turning Stone into Ebonstone, but cannot spread past Wood (nor several other block types, but Wood is arguably the easiest to acquire).
  • If a world remains in Hardmode for a long time, the Hallow/Corruption/Crimson can completely devour the Jungle. To farm Plantera, Chlorophyte Ore, or other jungle enemies, consider sealing off part of the underground jungle with Wood to ensure it is never corrupted.
  • If you enter Hardmode while a Corruption farm/arena is still standing unsealed near your town, quickly purchase several full stacks of Purification Powder from the Dryad and drench the Corruption with it. Alternatively, you can choose to simply limit the spread of Corruption by digging a four-tile-wide gap around the affected area and sealing it in with Wood. You will need to move quickly, though.
  • Once you got the Steampunker, you might want to buy the Clentaminator for 2 platinum, along with its ammunition, named Solution. It is a quick and handy way of cleaning/destroying/creating biomes. Be aware that, both the Clentaminator and the Solution will cost a lot of money.


  • When beginning Hardmode, a player can easily become overwhelmed by the difficult new enemies, which have Health and Damage many times greater than regular-mode enemies. It is advisable to start by identifying your most damaging weapons and investing money in Reforging them to acquire high damage bonuses, as well as reforging your Accessories to add high defense bonuses. Low-tier Hardmode weapons begin at around 35 damage, so viable regular-mode weapons of use will be the Sunfury and Night's Edge as melee options, the Molten Fury and Flamarang as semi-ranged, and the Flower of Fire and Demon Scythe as magical. Reforging these and making use of other damage boosts from Accessories or Armor bonuses can easily push these weapons into damage ranges that will make Hardmode fights relatively balanced.
  • Because hardmode relies more upon drops than treasure chests (which don't suddenly respawn with more loot), players will need to kill large numbers of these tougher enemies for items like Souls or Pixie Dust. Consider building mini-bases with proper protections that involve shallow lava pits above small access tunnels that run between Underground Hallow and Corruption/Crimson biomes. Use Active Stone Blocks to make the "doors" that let you jump up and grab floating souls. Place walls to prevent spawns inside your mini-base. You will still need to fight off the occasional Cursed Hammer, but it's a much easier job to farm these enemies when you reduce the threats to a few at a time. Eventually, they will drop either a good weapon, or the resources needed to craft one.
  • Mechanical bosses and invasions can take the player off guard. It's best to leave and rejoin if you are ill prepared.


  • Don't throw away your Iron Ore/Bars, Lead Ore/Bars, Bones, Lenses, Vertebrae, and Rotten Chunks, as these are used for crafting Boss-summoning items in Hardmode. If you need to collect more, it may be easier to create a new non-Hardmode world and collect them there, along with any other pre-Hardmode materials you find yourself needing.
  • The Eater of Worlds and Eye of Cthulhu are commonly used by players as a good source of money, and this is still useful during the beginning stages of Hardmode. However, summoning them in Hardmode can be more difficult: eg. you've probably destroyed any close Demon Altars (needed to craft the Worm Food and Suspicious Looking Eye), you may have demolished your nearby Corruption farm or Arena, and trips to the naturally-occurring Corruption are now more hazardous (Eater of Worlds must be summoned and fought within Corruption). It is much easier to simply create a new non-Hardmode world to farm these bosses, then use the funds collected from them in your Hardmode world. The Wall of Flesh can be farmed and drops about 8 Gold Coin, and items which each sell for approximately 3 Gold Coin.
  • One way to farm money in Hardmode once you become reasonably able to traverse the Underground Hallow (aside from using a glitch) is to collect Crystal Shards, which are common and sell for 1 Platinum Coin 59 Gold Coin 84 Silver Coin for a full stack of 999. Since they grow naturally on any pearlstone surface facing air, you can mine away stripes of pearlstone in areas you visit often to farm crystals more readily.
  • Farming the Destroyer once you can beat it is another way to make a considerable amount of money, since you can farm it without too much additional effort. Because it is relatively easy to kill quickly and can easily be meleed to death (avoiding spending any money on ammunition), the Hallowed Bars it drops can be crafted into Light Discs, together with the Souls of Might it also drops, and with Souls of Light which can be obtained in the Underground Hallow. Each Light Disc sells for 10 Gold Coin. As it drops 15-30 Hallowed Bars and 20-40 Souls of Might per kill, that is typically 3-7 Light Discs per run (if you have enough Souls of Light, that is). The Souls of Might it drops may also be sold for additional money, 80 Silver Coin each, which is another 16-32 Gold Coin per run if you don't spend the souls on Light Discs, in addition to the 12 Gold Coin the boss drops. In total, you net 42-82 Gold Coin, and due to the ease of crafting the Mechanical Worm and the relative quickness with which you can dispatch the boss, you can fight it multiple times in a single in-game night.
