Hardmode

This article is about the world mode. For the player character mode, see Hardcore.

Initial Hardmode map. Notice the "V" formation, representing the new Underground Corruption (dark purple) and Hallow (light pink) biomes, which each replace existing world blocks upon defeat of the Wall of Flesh. (Please note that this is a pre-1.2 map.)

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. One defense from the constant threat of Hardmode enemies is a Sky City.

Hardmode contains new Biomes called the Underground Corruption/Underground Crimson and The Hallow (along with the Underground Hallow). Corruption 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 in Hardmode.

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.

Biomes

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, The Hallow/Underground Hallow and Corruption/Underground Corruption (or Crimson/Underground Crimson), are generated, replacing large sections of the World in a "V" or "X" pattern that extends from the center of The Underworld all the way to the surface.

If either of the two diagonal stripes of The Hallow or The Corruption pass through an Underground Jungle, they will not overwrite it; this can cause small Hallows or Corruptions to spawn.

The Underground Corruption/Crimson looks similar to the surface Corruption/Crimson, though it contains several new Corruption/Crimson-themed enemies, like the Corruptor and Clinger.

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 spreads much more easily in Hardmode, with the Hallow spreading in a similar fashion.

• 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 and Hallow, including Wood, Clay Blocks, Ash Blocks, Silt Blocks, Obsidian, Ores, Gems, and all bricks.
• Dirt underground is immune to corruption, and chunks of dirt large enough to prevent any stone from reaching 3x3 areas will functionally stop the spread of hallow, crimson, or corruption.
• 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 does not impact mud - a jungle can be "inoculated" by using Holy Water to spread hallow in the stone near underground jungles before corruption can get to the jungle.
• Hallow and Corruption cannot convert each other.

These new properties mean that Hallow and Corruption will now continuously spread, and can reach your original spawn point within a few in-game days. It is advisable to take steps to protect your Town and any other 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.

Alternate methods of saving your town are to either build a Sky City or bury your town in an inaccessible-to-enemies location, preferably using shallow lava moats to protect it. So long as every background space that is accessible has a wall, no enemies will spawn in.

Ores

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

• The first destroyed Demon Altar or Template:Pc iconCrimson Altar will trigger the creation of Cobalt Ore or Template:Pc iconPalladium Ore.
• The second destroyed Demon Altar or Template:Pc iconCrimson Altar will trigger the creation of Mythril Ore or Template:Pc iconOrichalcum Ore.
• The third destroyed Demon Altar or Template:Pc iconCrimson Altar will trigger the creation of Adamantite Ore or Template:Pc iconTitanium Ore.

The new ores are created by replacing existing World blocks.

Subsequent Demon Altars or Template:Pc iconCrimson Altar destroyed will begin the cycle again, though the fourth-sixth altars will drop half as many ore as the first ones, the seventh-ninth will drop only one third of the ore of the first ones, and so forth. The formula is 1/ROUND_DOWN([number of destroyed altars]/3).

Each time a demon altar or Template:Pc iconCrimson Altar is destroyed, there is also a chance that a single random tile of rock in the world will be converted into ebonstone or pearlstone, which will likely grow to become a new underground Hallow or Corruption if 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

• Mining Cobalt Ore or Template:Pc iconPalladium Ore requires at least the Molten Pickaxe.
• Mining Mythril Ore or Template:Pc iconOrichalcum Ore requires at least the Cobalt Drill, Template:Pc iconCobalt Pickaxe, Template:Pc iconPalladium Drill, or the Template:Pc iconPalladium Pickaxe. Crafting many higher-tier Hardmode items will require a Mythril Anvil or Template:Pc iconOrichalcum Anvil, which is crafted from 10 Mythril Bar or Template:Pc iconOrichalcum Bars.
• Mining Adamantite Ore or Template:Pc iconTitanium Ore requires at least the Mythril Drill, Template:Pc iconMythril Pickaxe, Template:Pc iconOrichalcum Drill, or Template:Pc iconOrichalcum Pickaxe. Crafting Adamantite Bars or Template:Pc iconTitanium Bars will require an Adamantite Forge or a Template:Pc iconTitanium Forge, which is crafted from a Hellforge and 30 raw Adamantite/Titanium Ores.

Enemies

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

Most of these enemies are significantly harder than the player may initially be ready for upon reaching hardmode. Not only do they have many more hitpoints, they also have defense that can render most Pre-Hardmode weapons ineffective, are much more resistant to knockback, and many of them either shoot projectiles or have AIs or forms of movement that invalidate older methods of handling enemies. Enemies also do far more damage than the player can regenerate normally without extreme defense values, forcing players to find ways to severely limit the damage they can take.

Bosses

New Hardmode bosses are "upgraded" versions of the regular-mode bosses, are much more difficult, and are summoned via new craftable items:

• The Destroyer is the Hardmode version of Eater of Worlds, and is summoned by the Mechanical Worm. This is generally considered the easiest Hardmode boss, even though the Eater of Worlds is the mid-difficulty boss in regular mode.
• The Twins are the Hardmode version of the Eye of Cthulhu, and are summoned by the Mechanical Eye.
• Skeletron Prime is the Hardmode version of Skeletron, and is summoned by the Mechanical Skull.
• Plantera is a new Hardmode boss available after the 1.2 update. It is a giant plant-like monster that has a similar AI to The Destroyer, but not as simple.
• Golem is the hardmode boss found in the Lihzahrd dungeon.

All regular-mode bosses can still be summoned in Hardmode.

NPCs

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). 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 and the Red/Green/Blue lights.
• The Steampunker appears after defeating one hardmode boss and if a vacant house is available. She sells teleporters and other steampunk items.
• 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.
• The Pirate appears once you have defeated a Pirate Invasion, and sells a vanity set as well as other pirate themed items.

Events

There are currently two new events in Hardmode: The Frost Legion, which is triggered by the Snow Globe. It can be considered the Hardmode version of the Goblin Army, though it requires summoning by the player and never invades on its own, and Pirate Invasions, also similar to Goblin Armies.

• In Hardmode worlds, Goblin Armies do still invade, and Meteorites still land, each at their regular rates.
• The Snow Globe can be used to summon the Frost Legion in non-Hardmode worlds, but the Snow Globe itself can only be acquired in a Hardmode world.
• Blood Moons also occur just as frequently as in regular mode. The new night time Hardmode enemies will also swarm your Town, including Possessed Armor, Wraiths, and Wandering Eyes. If the Blood Moon coincides with a Full Moon, Werewolves will also attack.
• As of 1.2 there are also Solar Eclipses, which behave like the Blood Moon, only during the day. During a Solar Eclipse, unique and powerful monsters will spawn in vast numbers, including Reapers, Vampires, Swamp Things, Frankensteins and Eyezors.
• As of 1.2.1 (Halloween Update), there is the Pumpkin Moon which 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.

Items

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 the Hardmode versions of Pickaxes, Axes, and Bows, respectively.

Armor/Tool/Weapon sets

Each of the six new Ores has its own complete item set, including Armor, Drill, Chainsaw, Sword, Spear, and Repeater. In addition, the highest-tier Hallowed Armor and associated Hallowed tools and weapons become available: the Drax, Excalibur, Gungnir, and Hallowed Repeater. Crafting Hallow-tier items requires either first creating all of the other new item sets and defeating all three new Hardmode Bosses (see above), or just defeating the Hardmode bosses as of the 1.2 update.

Each new Armor set has three different options for the Helmet slot, which each boost a different weapon type (though these rules are slightly different for the Hallowed Armor, see its article for details):

• The Headgear provides a boost to Magic Weapons.
• The Helmet provides a boost to Melee Weapons.
• The Mask provides a boost to Ranged Weapons.

Magic weapons

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

Crystal Storm

Cursed Flames

Magic Dagger

Ice Rod

Golden Shower

After killing The Twins, the following become craftable:

Magical Harp

Rainbow Rod

Other weapons

Before beating Bosses:

• Dao of Pow deals some very high damage at reasonable range.
• Phasesaber is an upgraded Phaseblade, adding rapid-fire attack and double the melee damage.

After defeating The Destroyer:

• Light Discs help you traverse the new biomes.
• Megashark helps you beat the remaining Hardmode bosses.

After defeating Skeletron Prime:

• Flamethrower lets you use all that Gel you've got saved up as powerful ammunition.

Accessories

Compass • Cross Necklace • GPS • Moon Charm • Music Box • Neptune's Shell • Philosopher's Stone • Star Cloak • Titan Glove • Wings

Crafting materials

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:

• Pixie Dust (from Pixies) is used in Greater Healing Potion and Holy Arrows
• Unicorn Horn (from Unicorns) is used in Holy Arrows
• Cursed Flame (from Clingers and World Feeders) is used in Cursed Bullets/Arrows
• Crystal Shards (grows in the Underground Hallow) are used in Crystal Bullets.

Note: See The Hallow, Underground Hallow, Corruption, and Underground Corruption for complete item drop lists. See also Hardmode weapons.

Notes

• You can use a map editor to convert a world back to normal difficulty after defeating the Wall of Flesh.
• Hardmode should not be confused with hardcore mode, which is for the character, not the world.
• Clowns have a chance to appear during Blood Moons.
• Demonite Ore and Crimtane Ore do not spread the Corruption and Crimson during hardmode.

Tips

Corruption and Hallow spread

• 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 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.
• The Hallow and/or The Corruption can eventually overtake all the Sand in a map. Sand is essential in crafting Glass and then Bottles for Potions, so collect a large amount of it early on. Pearlsand/Ebonsand cannot be used to craft Glass. However, even when the Hallow/Corruption has completely taken over your world, Purification Powder/Vile Powder can be used to retake usable amounts of Sand. (Alternately, you can just spawn new worlds and plunder their sand.)

Difficulty

• 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.

Resources

• Don't throw away your Iron Ore/Bars, Bones, Lenses, 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 9 , and items which each sell for approximately 10 .
• The best way to make 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 40 GC per full stack. Since they grow naturally on any pearlstone surface facing air, you can mine away stripes of pearlstone in areas you frequent often to farm crystals more readily.

History

• 1.2: Jungle, Dungeon, Crimson and Snow biomes are all affected by hardmode now. Cobalt and Palladium drills can now mine Adamantite and Titanium.

• 1.1: Introduced.
