Bosses are large, aggressive, resilient enemies that offer a substantial challenge to players. Defeating bosses is usually instrumental in advancing the game in some way. Each has its own particular way of being summoned, and warning messages appear whenever one is about to appear. When the boss appears, its own special boss music will play, indicating that the fight has begun, along with a message saying it has arrived. Defeating a boss concludes with a congratulatory message and several items. Most of the bosses can pass through blocks, with the exception of King Slime, Lepus (Template:Mobile icon), Turkor the Ungrateful's body (Template:Mobile icon), and Golem. Bosses are the only enemies which appear on the minimap (apart from Dungeon Guardians) Template:Pc iconTemplate:Mobile icon, which allows the player to locate them easier.

Most bosses have items associated with them which summon them when used, usually directly, however some must be used with the help of another block to complete the summoning. Bosses that are summoned directly from items have other ways to be summoned, most commonly either appearing during nightfall or by breaking evil power orbs. Event-exclusive bosses only appear during said events.King Slime being the easiest and Ocram, or Moon Lord being the the most difficult

Quick Answers

How does defeating a boss in Terraria advance the game? toggle section
In Terraria, defeating a boss is a significant event that propels the game forward. Each boss defeated usually grants the player new materials, which can be used to craft higher tier items like pickaxes. This progression allows players to explore new areas, face tougher enemies, and continue their journey towards becoming as strong as possible. The order of bosses in Terraria can vary, but each one presents a unique challenge and contributes to the overall progression of the game.

What are the conditions for manually summoning a boss in Terraria? toggle section
In Terraria, bosses can be manually summoned under specific conditions. Most bosses have associated summoning items that can be used to spawn them. For instance, Skeletron, one of the bosses, is summoned by speaking to the Old Man at the Dungeon's entrance at night and selecting the 'Curse' option. However, it's important to note that each boss has its own unique summoning method and conditions.

How many bosses are there in Terraria? toggle section
There are currently 8 pre-Hardmode, 11 Hardmode, and 14 event bosses (33 in total) in Terraria. Each boss presents a unique challenge and defeating them is usually instrumental in advancing the game in some way. For instance, they often grant the player new materials for crafting higher tier items.

What is the progression of bosses in Terraria? toggle section
In Terraria, boss progression typically starts with the Eye of Cthulhu, followed by either the Eater of Worlds or Brain of Cthulhu based on world the Corruption/Crimson. Skeletron must be defeated to enter the Dungeon, and the Queen Bee is found in the Jungle. The Wall of Flesh triggers Hardmode and is followed by the Mechanical Bosses (Twins, Destroyer, Skeletron Prime). Plantera in the Jungle is a key Hardmode boss, leading to Golem and the Lunar Events. The final boss, Moon Lord, concludes the game. Each boss drops unique items crucial for advancing and defeating tougher challenges in Terraria's expansive world. Some bosses (like the King Slime, Duke Fishron, etc.) are optional and it's not necessary to defeat them.

Pre-Hardmode Bosses

These are the first bosses the player can encounter. Usually, defeating one of these bosses will give the player items and materials necessary to progress in the game, eventually leading to Hardmode.

King Slime

King Slime with Ninja
King Slime Trophy
Slime Crown
For strategies on defeating the King Slime, see Guide:King Slime strategies.

King Slime is a giant blue slime with 2000 health. It is summoned with a Slime Crown, and can also rarely appear in the outer thirds of the map completely by itself. As with all monsters that can spawn naturally, the King Slime has a better chance of spawning while standing near a placed Water Candle, under the effects of a Battle Potion or after killing 150 slime during a Slime Rain. King Slime is a good challenge for a beginning player, and can be easily defeated by tactical use of terrain.

In the PC version, King Slime gains the ability to shrink to nothing and re-appear directly on top of the Player.

King Slime does not provide access to game-advancing items upon defeat, but outside Expert Mode will drop one Gold Coin, one piece of Ninja clothes, and one of several slime-related items.

In Expert Mode, the King Slime has much more health and can summon Spiked Slimes, that are similar to the Spiked Jungle Slime and Spiked Ice Slime.

Eye of Cthulhu

Eye
Eye of Cthulhu Trophy
Suspicious Looking Eye
For strategies on defeating the Eye of Cthulhu, see Guide:Eye of Cthulhu strategies.

Eye of Cthulhu has a 1 in 3 chance of spawning at the beginning of each night, once the player has 200 HP or more, 3 or more NPCs living in houses, and over 10 Defense. It will continue to do so until defeated for the first time. It has 2800 health in all. It can also be summoned using a Suspicious Looking Eye at night. This is generally the first boss a player must face. It travels through blocks, and spawns Servants of Cthulhu.

In Expert Mode, the Eye of Cthulhu will do a fast chain dash in its second phase, using the attack more often the lower health it has. This can lead to it dashing almost continually at very low health, making it especially difficult for players in the early game to finish it off.

Eater of Worlds

Eater of Worlds
Eater of Worlds Trophy
Worm Food
For strategies on defeating the Eater of Worlds, see Guide:Eater of Worlds strategies.

Eater of Worlds will appear after every third Shadow Orb is broken or after Worm Food is used. These orbs are found in the Corruption chasms, surrounded by Ebonstone, which requires a Pickaxe with 65% power or higher to mine, although explosives or Purification Powder can be used to bypass this. Once within range, shadow orbs can be destroyed with a Hammer. Eater of Worlds can also be summoned with the Worm Food. Eater of Worlds can only be summoned in the corruption, and if it manages to escape the corruption, it will flee and disappear.

Eater of Worlds can be a challenge even for intermediate players, as it is a large worm-type enemy that travels through tiles, and is made up of multiple sections that can each attack separately (with separate heads, no less) when they are cut off. To defeat this boss, every section must be brought down to less than two body parts to be killed (the smallest possible section is a head and a tail with no body pieces). Due to how helpful corrupted items are, this will probably be the second boss faced in worlds that have corruption, rather than Crimson.

Eater of Worlds is the only source of Shadow Scales in the game, and drops a large amount of Demonite Ore, which can also be sold for over 7/stack, making this technically the best pre-hardmode boss for farming in the game.

In Expert Mode, the boss is able to shoot dark-green projectiles at you, called 'Vile Spit', similar to that of a Corruptor.

Brain of Cthulhu

Brain of Cthulhu
Brain of Cthulhu Trophy
Bloody Spine
For strategies on defeating Brain of Cthulhu, see Guide:Brain of Cthulhu strategies.

Brain of Cthulhu will appear after every third Crimson Heart is broken. These hearts are found in the Crimson's chasms, surrounded by Crimstone, which can be bypassed with the same methods Ebonstone can. However, some of the pockets containing these will generate open. Once within range, Crimson Hearts can be destroyed with a Hammer or any tile-breaking explosive. Brain of Cthulhu can also be summoned with a Bloody Spine. It can only be summoned in the Crimson and can be at anytime of day.

Brain of Cthulhu has only 1,000 HP but has two forms. In the first form, the brain cannot be harmed and Creepers will float around it. After these are killed the brain will go into its second form, where it will teleport more frantically and move a lot faster, so a ranged weapon may be needed. The Brain of Cthulhu's second attack form is ramming, alike the second form of Eye of Cthulhu. Unlike most other bosses, the Brain of Cthulhu is not immune to knockback.

In Expert Mode, the Brain of Cthulhu will have more health, and in its second phase, it will start creating illusions of itself to charge at the player. The lower the Brain of Cthulhu's HP gets, the illusions become much less obvious to the point where they will look exactly like the Brain of Cthulhu.

Brain of Cthulhu is the only source of Tissue Samples in the game (Other than the creepers spawned while fighting it), and drops a large amount of Crimtane Ore, which are their equivalents to the corruption items.

Queen Bee

Queen Bee
Queen Bee Trophy
Abeemination
For strategies on defeating Queen Bee, see Guide:Queen Bee strategies.

Queen Bee is summoned by destroying the Queen Bee's offspring encased in honey in the beehive structure, located in the underground jungle, or by the use of an Abeemination anywhere in the jungle. It is the only source of Bee Wax, except on the console. Queen Bee is immune to knockback.

Queen Bee alternates between charging at the player (faster in Expert Mode) and hovering above them whilst spawning bees.

Defeating Queen Bee does not advance the game in a major sense, but it does provide some nice loot.

Skeletron

Skeletron Head
Skeletron Trophy
Clothier Voodoo Doll
For strategies on defeating Skeletron, see Guide:Skeletron strategies.

Skeletron is summoned by speaking to the Old Man and activating his curse at the entrance of the Dungeon at night. Skeletron will alternate between attacking the player with its hands, and performing a spinning attack. Its hands can be attacked and defeated to make the battle easier, although this is not required. If it has not been defeated before the night is over, Skeletron will attack and kill the player in one hit.

Defeating Skeletron will stop the Dungeon Guardians from spawning, allowing free access to the Dungeon. It can be summoned again by killing the Clothier with the Clothier Voodoo Doll equipped at night.

In Expert Mode, the fight is much harder. In the first phase, Skeletron's head is immune to damage until its hands are destroyed. Once they are destroyed, it will start shooting homing skulls at the player. Expert Mode Skeletron is much faster. Its hands inflict the Slow debuff, and its head inflicts Bleeding.

Wall of Flesh

Wall of Flesh
Wall of Flesh Trophy
Guide Voodoo Doll
For strategies on defeating the Wall of Flesh, see Guide:Wall of Flesh strategies.

The Wall of Flesh is summoned by throwing the Guide Voodoo Doll into a pool of lava in the Underworld while the Guide is alive. It is known by most players as the hardest pre-Hardmode boss, at 8,000 health, and defeating it will irreversibly enable Hardmode in that given world. Its defeat will also allow the creation of the summoning items for various Hardmode bosses.

It can drop several powerful items, one of them being the guaranteed drop Pwnhammer which can be used to break Demon Altars in order to spawn Hardmode Ores.

In Expert mode, the hungry will rapidly respawn, and the wall will greatly increase speed when it has (specific amount needed!) hp remaining. The hungry will block attacks and deal quite a bit of damage, and the rapid speed change can easily kill unsuspecting players.

Hardmode Bosses

Hardmode Bosses are significantly harder upgrades of and new additions to previous bosses. Defeating them is usually instrumental in advancing the game in some way. Each has its own particular way of being summoned, and warning messages appear whenever one is about to appear. Defeating a boss concludes with a congratulatory message and several items.

During Hardmode, each night has a one in two chance of spawning one of the three Mechanical Bosses that have not yet been defeated in the current world. This only happens after removing at least one Altar from the world, so it may be advisable to refrain from doing so if the player is not ready for a challenging fight.

The Twins

File:Twins Boss.gif
Retinazer Trophy
Spazmatism Trophy
Mechanical Eye
For strategies on defeating The Twins, see Guide:The Twins strategies.

The Twins are the Hardmode version of the Eye of Cthulhu. They spawn as two eyes, one with 20,000 HP (Retinazer) and one with 23,000 HP (Spazmatism). Unlike the Eye of Cthulhu, they do not immediately transform at half health - Retinazer transforms at 8,000 HP and Spazmatism transforms at 9,000 HP. The Twins are summoned by using a Mechanical Eye at night. It is worth noting that The Twins will gain defense in their second forms, unlike the Eye of Cthulhu.

The two eyes have different fighting styles. Spazmatism focuses on slamming into the player and firing cursed flames. Once it reaches its second form, it will resemble a mechanical version of the Eye of Cthulhu's second form. It will deal a lot more damage, and the flames it shoots are more consistent like the Flamethrower instead of the Cursed Flames, but the flames will still inflict Cursed Inferno debuff on the player.

The other eye, Retinazer, focuses on shooting the player with Death Lasers like the Destroyer's Probes. Once it reaches its second form, it will replace its pupil with a laser cannon. During this form, it will shoot lasers extremely fast, sometimes having the same fire rate as a Megashark. The last Twin destroyed will drop all of the loot.

(This boss needs Expert Mode info)

Like the Eye of Cthulhu the Spazmatism looks similar and still does chain dashes.

The Destroyer

The Destroyer
Destroyer Trophy
Mechanical Worm
For strategies on defeating The Destroyer, see Guide:The Destroyer strategies.

The Destroyer is the Hardmode version of the Eater of Worlds (also with some Brain of Cthulhu features), with 80,000 HP. It is considered the easiest hardmode boss by many players, despite having the most health. Although it is similar to its Pre-Hardmode counterpart, it has some key differences: it won't divide into smaller segments, will shoot lasers from its body if space is available, and will deploy Probes to attack.

The Destroyer is summoned by crafting and using a Mechanical Worm anywhere, but can only be spawned at night. The Destroyer will shoot Death Lasers, increasing in attack speed as it loses HP. Weapons that do damage to multiple segments like Flails, Water Bolt, and the Demon Scythe are recommended, because they will hit multiple sections of The Destroyer at once.

(This boss needs Expert Mode info)

Skeletron Prime

Skeletron Prime
Skeletron Prime Trophy
Mechanical Skull
For strategies on defeating Skeletron Prime, see Guide:Skeletron Prime strategies.

Skeletron Prime is a far more difficult Hardmode version of Skeletron, with the head alone having 28,000 HP. Instead of two hands, it has a vice, laser gun, saw, and cannon. With the head and all limbs combined, Skeletron Prime has 59,000 HP. However, like Skeletron, only the head has to be defeated. Skeletron Prime can be summoned as many times per world as needed, by crafting and using a Mechanical Skull, but can only be summoned at night. It is worth noting that when his head spins, his Defense increases, unlike Skeletron, whose Defense is dropped to 0 when spinning.

He will drop Hallowed Bars and Souls of Fright, which are both used to craft many kinds of armor and tools. Be warned that when Skeletron Prime is still alive during morning (4:30 AM to 7:30 PM), it will spin rapidly, and deal enough damage to kill the player in one hit, despawning afterwards.

(This boss needs Expert Mode info)

Plantera

Plantera's First Form
Plantera Trophy
Plantera's Bulb
For strategies on defeating Plantera, see Guide:Plantera strategies.

Plantera is summoned prior to version 1.2.3 (and in the current console version) by destroying a Plantera's Bulb, which is found in the Underground Jungle after defeating all three mechanical bosses. (Only one on the Template:Console icon Template:Mobile icon Console/Mobile versions)

Plantera has two stages: In its first stage it clings to solid blocks using vine-like hooks. In this stage Plantera fires spiky projectiles much like Spiky Balls. In its second stage Plantera has increased speed and charges at the player. It will also release tendrils from its main body. In Expert Mode, the tendrils are attached to each hook instead (3 on each), adding approximately 9 tendrils. Once Plantera is defeated, the dungeon will automatically spawn hardmode monsters, such as the Paladin.

Golem

Golem
Golem Trophy
Lihzahrd Power Cell
For strategies on defeating Golem, see Guide:Golem strategies.

The Golem is summoned by using a Lihzahrd Power Cell at the Lihzahrd Altar in the Jungle Temple. In order to access the Jungle Temple, Plantera must be defeated to obtain the Temple Key.

Golem has two phases. During the first phase, its two fists and its head can be attacked. Like Skeletron, destroying the fists is not needed, but can be helpful. Once the head's health is depleted, it begins flying above the body while shooting fireballs and eye beams, leaving the body open to attack. The body will jump around and punch madly in this phase. Defeating the body will defeat Golem.

Duke Fishron (Template:Pc icon)

Duke Fishron
Duke Fishron Trophy
Truffle Worm
For strategies on defeating Duke Fishron, see Guide:Duke Fishron strategies.

Duke Fishron is a fish-pig-dragon hybrid with 50,000 health and 50 defense. It is summoned when a Truffle Worm is used as bait with a higher-powered fishing rod in an Ocean biome.

In its first stage, Duke Fishron will attempt to ram the player 5 times before either firing explosive bubbles or summoning Sharknados. In its second stage, Duke Fishron gains glowing eyes and a boost to attack and defense (needs confirmation.) Although its ramming attacks remain the same, instead of shooting bubbles directly at the player, it flies quickly around in circles, sending bubbles everywhere. Instead of summoning Sharknados in this stage, Duke Fishron summons larger Cthulhunados. These remain in place until Duke Fishron is defeated. Duke Fishron is said to be the hardest boss except for Moon Lord final boss, but the battle becomes much easier when the player has Wings equipped.

try to fight and kill this boss before pumpkin & Frost Moon it will make those events a lot easier

Lunatic Cultist (Template:Pc icon)

Lunatic Cultist
Lunatic Cultist Trophy
Mysterious Tablet
For strategies on defeating Lunatic Cultist, see Guide:Lunatic Cultist strategies.

The Lunatic Cultist is summoned by killing the four cultists which spawn outside of the dungeon when The Golem is defeated. When the Cultist is defeated the Lunar Events begin.

While the Lunatic Cultist has only one stage, its attacks become more powerful as it loses health. The Lunatic Cultist flies around randomly, cycling between shooting fireballs, creating a ball which shoots lighting in a circle, shooting a giant snowflake which shoots ice shards at the player, shooting shadowflames, and shooting five destructible projectiles twice in a row. The Lunatic Cultist also often will create copies of itself and attempt to summon a Phantasm Dragon. If the Phantasm Dragon is still alive, it will summon an Ancient Vision instead. Attacking a duplicate or waiting too long to attack the real Lunatic Cultist will cause the Phantasm Dragon or Ancient Vision to be summoned.

Moon Lord (Template:Pc icon)

Moon Lord
Moon Lord Trophy
Celestial Sigil
For strategies on defeating Moon Lord, see Guide:Moon Lord strategies.

The Moon Lord is the final boss of Terraria as of version 1.3.0.3 and drops most of the end-game items. He is summoned by defeating all four pillars of the Lunar Event.

The Moon Lord has two hands and a head which must be killed by attacking the eyes on them. When the three eyes are destroyed the Moon Lord's core opens up on his chest which then must be destroyed. The hands shoot two projectiles at once which home onto the player and will summon phantom versions of the True Eye of Cthulhu and throw them at the player.

The head will occasionally release a very powerful Phantasm Death Ray which partly sweep across the screen in the player's direction and will then shoot several homing projectiles much like the hands. When an eye is destroyed a True Eye of Cthulhu will be created which will pursue the player, summon phantom versions of itself which orbits itself and will throw them at the player, and occasionally create a smaller version of the Phantasm Death Ray. After all three eyes are defeated, the Moon Lord's core becomes vulnerable. When the core is killed, Moon Lord is defeated.

Event Bosses

Mourning Wood

Mourning Wood
Mourning Wood Trophy
Pumpkin Moon Medallion

Mourning Wood is a mini-boss that spawns during the Pumpkin Moon. Like many other bosses, it has the ability to move through necessary blocks. It shoots flaming projectiles, some of which pass through blocks.

One of its attacks include spitting flaming spikes out of its head at a very fast rate. These spikes stay on the ground for a while, dealing contact fire damage to anyone who steps on them.

Pumpking

Pumpking Full Body
Pumpking Trophy
Pumpkin Moon Medallion

Pumpking is also found later in the Pumpkin Moon event. Multiple Pumpkings can be out at the same time, up to six at the final fifteenth wave (or even more in multiplayer). It has three modes of attack, indicated by the face carved in the pumpkin it uses as a head.

One of its attacks include it spawning scythe-like beams from its arm blades, which act similarly to a Demon Scythe.

Everscream (Template:Pc icon Template:Console icon)

Everscream
Everscream Trophy
Naughty Present

Everscream can be found during the Frost Moon and acts much like the Mourning Wood. The biggest difference is that its projectiles can NOT go through blocks.

Flying Dutchman (Template:Pc icon)

Flying Dutchman
Flying Dutchman Trophy
Pirate Map

Flying Dutchman is the boss of the Pirate Invasion. It will initially spawn after 65% of the invasion is completed.

It has four cannons that must be destroyed before it can die. The Flying Dutchman does not disappear after the invasion is over, but it will explode if it has not been engaged before said ending occurs. Several Flying Dutchmen can appear at once.

Martian Saucer (Template:Pc icon)

Martian Saucer
Martian Saucer Trophy
Martian Probe

Martian Saucer is a large flying boss that spawns during the Martian Madness event.

The Martian Saucer moves through blocks, and has four turrets with independent health meters that must each be destroyed before damaging the saucer itself becomes possible. The turrets include two rocket launchers and two laser machine guns. In addition, the saucer itself fires a large beam ("death ray") that can only fire directly downward, and which cannot be destroyed independently. The player can damage the core only if all four turrets have been destroyed.

Solar Pillar (Template:Pc icon)

Solar Pillar This is one of the four bosses that spawn during the Lunar Events that start once the Lunatic Cultist has been
Lunatic Cultist

defeated. After all 4 Celestial Towers are defeated, the Moon Lord will spawn.

The pillar itself doesn't do much to attack the player, mainly summoning enemies instead, but it does cause solar fragments to rain non-stop from the sky. It is surrounded by a large, impenetrable force field until 100 of its minions have been slain (150 in Expert Mode). The enemies it spawns are melee-based. It is highly recommended to stay on the ground, as the Crawltipedes it spawns only target airborne players. After 100/150 minions are killed, the force field around it will dissipate, allowing players to attack it.

The Solar Pillar spawns the following enemies:

Nebula Pillar (Template:Pc icon)

Nebula Pillar This is one of the four bosses that spawn during the Lunar Events that start once the Lunatic Cultist has been
Lunatic Cultist

defeated. After all 4 Celestial Towers are defeated, the Moon Lord will spawn.

While the pillar itself doesn't do anything to attack the player, it spawns magic-based enemies. It is surrounded by a large impenetrable force field until at least 100 (150 in Expert Mode) of its minions are slain. After the 100/150 minions are killed, the force field dissipates, allowing the player to attack it directly.

The Nebula Pillar spawns the following enemies:

Vortex Pillar (Template:Pc icon)

Vortex Pillar This is one of the four bosses that spawn during the Lunar Events that start once the Lunatic Cultist has been
Lunatic Cultist

defeated. After all 4 Celestial Towers are defeated, the Moon Lord will spawn.

The pillar itself doesn't do much to attack the player, only occasionally spawning a Giant Magnet sphere sort of attack, similar to the Lunatic Cultist's one. It spawns ranged-based enemies. After 100 (150 in Expert Mode) of its minions have been slain, the force field around it will dissipate, leaving it open to the player's attacks.

The Vortex Pillar spawns the following enemies:

Stardust Pillar (Template:Pc icon)

Stardust Pillar This is one of the four bosses that spawn during the Lunar Events that start once the Lunatic Cultist has been
Lunatic Cultist

defeated. After all 4 Celestial Towers are defeated, the Moon Lord will spawn.

The pillar itself doesn't attack the player much, but it is the only pillar with a damaging enemy-spawning animation. As with the other pillars, it is surrounded by an impenetrable force field that is only broken when 100 (150 in Expert Mode) or more of its minions are slain. Once the force field is broken, the player can attack the pillar at will.

The Stardust Pillar spawns the following enemies:

Console/Mobile (Template:Console icon Template:Mobile icon)

Achievement Exterminator Exterminator is the achievement you earn for defeating every boss in the game (Template:Console icon Template:Mobile icon only).

Notes

  • The spawning messages for all the bosses are:
    • Eye of Cthulhu: "You feel an evil presence watching you..."
    • Eater of Worlds and Brain of Cthulhu: "A horrible chill goes down your spine..." after the first and "Screams echo around you..." after the second Shadow Orb/Crimson Heart is broken. The third only produces a standard summon message.
    • The Destroyer: "You feel vibrations from deep below..." or "You feel a quaking from deep underground..."
    • The Twins: "This is going to be a terrible night..."
    • Skeletron Prime: "The air is getting colder around you..." or "You feel the air getting colder around you"
    • Moon Lord "Impending doom approaches…"
  • As of 1.2.3, worlds generated in earlier versions, in which a player defeated all mechanical bosses before upgrading, will not have those bosses register as defeated; for instance, Plantera's Bulbs will not spawn, and the Steampunker will not arrive.
  • There are currently 29 different/unique bosses (18 (Template:Pc icon), 18 (Template:Console icon) and 17 (Template:Mobile icon)) in the game.
  • On the Template:Mobile iconMobile version, all loot from a boss will appear directly on the player.
  • All bosses have significantly lower health on the Template:Mobile iconMobile version. This is most likely to make up for the Mobile version's shorter nights and smaller underworld.
  • A cheap way to fight bosses that have summoning items is by crafting the item, summon the boss, then quickly put the item back into the inventory so the item won't be consumed. Also useful for trying to collect trophies.
