Boss Monsters are Monsters that are much harder to kill than other monsters. Any boss monster generally has much stronger attacks than a normal enemy, more defense, and considerably higher HP ranging from 2000 to 145000. 2800 to 217500 in Expert Mode. In addition, most boss monsters have their own unique AI, allowing them set movements to go by. Since update 1.2, all bosses can drop a unique trophy (~10% drop rate) that can be placed on a wall for display. In Master Mode bosses drop the mode drops with treasure bags and can drop relics which are in remembrance of defeating that boss in Master Mode.

Many bosses can be summoned by an item such as a Suspicious Looking Eye, Worm Food or Suspicious Looking Skull. (applies only to old gen consoles)

Certain bosses occasionally spawn themselves in when the player (or all players in a multiplayer world) meets certain criteria, differing with each boss. The spawn will not be interrupted even if the player is not ready, or AFK, but can be bypassed by quitting the world. The bosses that can spawn without summoning items are Eye of Cthulhu, The Destroyer, Skeletron Prime, The Twins, and King Slime.

The criteria and message for each boss can be found in their article.

King Slime
King Slime Trophy
Main article: King Slime

The King Slime, as one might gather, is a slime. It is blue in color and enormous, roughly 10 blocks wide and 5 blocks high. It will decrease in size and spawn Spiked and Blue Slimes when it takes damage. It appears to have a Ninja trapped inside it.

King Slime is summoned with the item Slime Crown, crafted with a Gold Crown and 20 gel at a Demon Altar. It can also be summoned if enough slimes are killed during a Slime Rain, or with a 1/100 chance in the outer thirds of the world. There has been a bug associated with the King Slime, sometimes causing the boss to not spawn/appear. This may be due to the fact that he spawned inside a cave and cannot get out.

The King Slime actually drops a little amount of Gel when he dies, and all of the blue slimes spawned when the King Slime is attacked also drop gel. The King Slime also drops gold coins, a piece of the Ninja Set and some lesser healing potions.

The King Slime is one of the biggest slimes in the game, second only to Queen Slime.

Main article: Eye of Cthulhu
Npc 4.gif
Eye of Cthulhu Trophy
The Eye of Cthulhu (commonly referred to as The Eye or EoC) is usually the first boss players will encounter. The Eye comes in two forms. The first form has 15 attack and spawns Servants of Cthulhu, while the second form has 23 attack and throws itself at the character``. The Eye of Cthulhu can be summoned by using a Suspicious Looking Eye (which can either be found in random chests or can be crafted from 6 Lenses at a Demon Altar) at night. The Eye can also spawn itself if certain criteria are met (having 200 HP and 3 NPCS) . While playing, the player may get the message "You feel an evil presence watching you...", which means that the Eye will awaken soon. After a few minutes the message "The Eye of Cthulhu has awoken!" will appear and the boss will promptly start to attack the player.

Players can summon The Eye anywhere, as long as it is night. Sometimes when underground the player may see "You feel an evil presence watching you...", though the Eye will not spawn naturally whilst they are underground, and will instead spawn as soon as the player returns to the surface.

Boss 1 will play during the fight.

Main article: Eater of Worlds
Eater of Worlds
Eater of Worlds Trophy
The Eater of Worlds is a worm-type boss monster. It can be summoned in the Corruption by smashing three shadow orbs or by using Worm Food, which can be crafted at a Demon Altar - however, it can only be summoned in The Corruption.

The Eater of Worlds has 53 parts in three segments; head, body, and tail. To beat this boss all segments must be slain. If the head is destroyed, the next body segment will automatically take its place as a head. The same happens with the tail. If a body segment is destroyed, it will split into two separate worms. Overall, if the heads are avoided with a massive attack of 40 damage, the boss is fairly easy to defeat, especially with weapons that deal damage multiple times per strike, such as the Vilethorn or the Ball O' Hurt.

It is the only boss that can drop Shadow Scales, which are needed to craft Shadow Armour and the Nightmare Pickaxe. It's Crimson equivalent is the The Brain of Cthulhu.

Boss 1 will play during the fight.

Main article: Brain of Cthulhu
Brain of Cthulhu's two forms
The Brain of Cthulhu is the alternative to Eater of Worlds if the world has Crimson. Brain of Cthulhu can be summoned using an item called "Bloody Spine". Otherwise, the player can also summon the boss by breaking Pulsating Heart (orbs similar to the Eater of Worlds). Instead of having segments like the Eater of Worlds, it has minions called Creepers that orbit it and fly off occasionally to attack. It teleports all this time, and it is invincible until all Creepers are killed. Then it morphs into its 2nd form and has 1000 health, and tries to attack by charging the character. It is the only boss to drop Tissue Samples, which is the Crimson version of Shadow Scales used to craft many Crimson materials.

Queen Bee (Attacking)
Main article: Queen Bee
Queen Bee Trophy
The Queen Bee is a boss that is summoned by breaking a larva type object found in a hive which spawns in the Underground jungle. Once spawned the Queen will begin to alternate between diving attacks from either side of the screen, and hovering above the character, either shooting stingers or spawning tiny bees.

Main article: Skeletron


Skeletron Trophy
Skeletron is a boss which can be defeated as many times per world as wanted using the Clothier Voodoo Doll. The first way to summon him is to talk to the Old Man in front of the dungeon at night and choosing the option "Curse". It is advised to be prepared because after that he will transform into Skeletron and attack. His hands each have 800 HP and his head has 4400 HP. His hands do 30 damage if they touch the character and his head will do a spin attack that does 35 damage. Players need to be quick to defeat this boss and summon him at the very beginning of night because once dawn comes Skeletron will hit for 9,999 damage, resulting in instant death. If the character dies before defeating Skeletron, he cannot be fought again until the next night, when the Old Man will respawn.

After defeating Skeletron, the player will gain access to the Dungeon.

Main article: Wall of Flesh
WoF Trophy
The Wall of Flesh (commonly abbreviated as WoF) is an aptly named wall made out of flesh that is the height of the entire Underworld Biome. It is the main boss of the Underworld, and defeating it in a world will permanently activate Hard Mode for that world. It is summoned only when the Guide is killed by allowing a Guide Voodoo Doll to fall into lava in the Underworld (Ensure the guide is alive when dropping the voodoo doll in, or it won't spawn the WoF). The Wall of Flesh moves constantly in the same direction, forcing the player into an on-the-run battle. It is impossible to fight the WoF behind it because it will immediately pull the player back to front, and with the time being the player can not use any items or move. The player also dies instantly once attempting to exit the Underworld.


Lunar Bosses

Main article: Ancient Cultist
Ancient Cultist
Ancient Cultist Trophy
The Ancient Cultist (otherwise known as the Lunatic Cultist) is a post-Golem boss that is summoned by visiting the dungeon once spawn conditions are filled, then killing the four Cultist NPCs (two melee, two ranged) that are worshiping a large, golden, glowing disk at the entrance of the dungeon. Upon doing this, the Ancient Cultist will spawn and begin attacking in three primary modes:
  1. Spawns a burst of three homing fire balls which explode on impact.
  2. Fires a large ice-ball which emits ice shards in six directions as it slowly flies in a single direction.
  3. Spawns an energy orb which fires large bolts of lightning at the player.

Occasionally, he will also spawn clones of himself (up to five) and attempt to summon a Phantasm Dragon, this is indicated by the Ancient Cultist and his clones arranging themselves around a glowing summoning circle and can be interrupted by correctly choosing and attacking the real Ancient Cultist. The real cultist has a stripe on his hat and a glimmer in his eye.

All four Celestial Pillars

The four Celestial Pillars spawn in four preset location ranges on the surface of your world once the Ancient Cultist is defeated. The position of each pillar is random among these ranges and can change each time you face them. When they spawn, they have 20,000 HP and are covered by a shield making them invulnerable until 100 (150 in Expert Mode) pillar-specific monsters (each pillar has its own range of monsters that it spawns) have been disposed of. Once those have been killed the shield dissipates, allowing players to attack them directly. Each of the pillars also has its own attack pattern, which is active both when the shield is up and when it's gone.

Main article: Moon Lord
Moon Lord
Moon Lord Trophy
The Moon Lord is summoned by defeating the four celestial pillars, which spawn at four preset locations (though which pillar spawns where randomizes) throughout the surface. These are summoned by defeating the Lunatic Cultist. He is the final boss.

Main article: Flying Dutchman

Flying Dutchman is a Hardmode boss that spawns during the Pirate Invasion. It is invincible and appears as a giant ship. Its purpose is to spawn pirate enemies. It sports cannons that shoot out explosives. The cannons can be destroyed. Once the cannons are destroyed, the ship is entirely destroyed. Each of four cannons has 2000 HP, making 8000 HP total.

Martian Saucer
Main article: Martian Saucer

Mourning Wood have 3 different kind of attacks: shooting fire projectiles that pierce through solid objects, spraying a cluster of lingering flames onto the ground, and hurting the player by touch.

The best strategy for taking out Mourning Wood is to used ranged attacks, as their piercing shots come at random intervals and are difficult to dodge. Ranged, Magic, or high knockback weapons are recommended.

Pumpking -- without arms.
Main article: Pumpking

The Pumpking is a Hardmode boss that spawns during the Pumpkin Moon. It behaves very similarly to Skeletron. It has two lengthy arms, each with a large scythe. These hands act much like Skeletron's hands, but they are indestructible.

It is considered the final boss of the Pumpkin Moon, and subsequent waves after its appearance increase the number of mobs. There can be a large number of Pumpkings attacking at once in the later stages (up to 6 active at the same time).

Main article: Everscream

Everscream is a miniboss in the Frost Moon event and is comparable to the Mourning Wood. It is a pine tree with red glowing eyes and is covered with snow. Everscreams appear in the fifth wave and onward of the event.

More info needed

Ice Queen
Main article: Ice Queen
More info needed

The Ice queen is the Final Boss of The Frost Moon Event. The Ice Queen attacks with three phases. It could either swoop down quickly to touch the player, causing high damage to the player in a short time. Second, it could spin around while quickly spawning frost shards that go in random directions. These frost shards do decent damage, but if many of them hit the player, it could kill the player quickly. Another phase is that it could shoot frost waves that have high velocity and can go through blocks. It does quite high damage and is fired at a fast rate towards the player, so players might find this phase difficult. Once killed she has a 16.6% chance to drop one of the following: Snowman Cannon, North Pole, Blizzard Staff, Baby Grinch Mischief's Whistle, or Reindeer Bells.

Main article: Betsy
More info needed
Betsy is the final boss of the Old One's Army Event and only appears at wave 7, after Golem has been defeated. Betsy is the only dragon to appear in Terraria. It has an attack pattern that is similar to Duke Fishron's swooping attack and will circle the area and breathe fire. Betsy will focus on defeating the player instead of attacking the Eternia Crystal.


The Wyvern in all its majesty.
Main article: Wyvern

The Wyvern is a large Hard Mode miniboss. It is a curling, dragon-like creature that attacks at high speed.

Wyvern is not summoned - it occasionally spawns in the sky, around the same point that Harpies spawn. It spawns without warning, so the player should be careful when they are at a high elevation in hardmode.

Ice Golem
Main article: Ice Golem

Ice Golems are an Uncommon miniboss. They spawn in Snow Biomes after activating Hard Mode, during a Blizzard. They will spawn more often during a Blood Moon. Ice Golems are hostile and thus attack the player. While they are able to deal damage by physical contact, they are very slow and will shoot at the player with lasers from afar, which also have a chance to cause a debuff. They are affected very little by knockback, but have a low jump height of only about 3 blocks.

The Paladin
Main article: Paladin

The Paladin spawns rarely in Hard Mode Dungeons. It throws hammers that will go through walls at the player and will try to walk into the player. When taking constant damage it will stop throwing hammers, but will still walk towards the player, as it is unaffected by knockback.

Goblin Summoner
Main article: Goblin Summoner

The Goblin Summoner is a miniboss found in Hardmode Goblin Invasions. It has 2000 health and the ability to fly at high speeds. Its primary attack method is shooting Chaos Balls. It will also occasionally summon Shadowflame Apparitions.

Main article: Dreadnautilus
The Dreadnautilus is an optional Hard Mode mini-boss. The Dreadnautilus can be fished up and fought (similar to Duke Fishron) during a Blood Moon event in early Hard Mode, finally the Dreadnautilus came out in the Version History update and came out in the 1.4 Journey's End Update.

Pirate Captain
Main article: Pirate Captain

The Pirate Captain are a Hard Mode miniboss that spawn as part of the Pirate Invasion. Out of all the pirates, they are the strongest and have the most defense. They are also quite resistant to knockback. They can be very deadly due to their cannon, which is able to inflict large amounts of damage to a player.

Main article: Mothron

The Mothron is a miniboss that spawns rarely as part of the Solar Eclipse event after all Mechanical Bosses are defeated.

It seems to have a charge pattern similar to that of the Queen Bee. Players should be advised that this enemy can charge through walls that are at least two blocks thick. As the player fights Mothron, it will lay Mothron Eggs which, after a while, will hatch into Baby Mothrons that have a similar attack pattern to the parent.

Corrupt Mimic
Crimson Mimic
Hallowed Mimic

The three special Mimics spawns rarely in the Underground Corruption, the Underground Crimson, and the Underground Hallow. They are a bigger, more offensive Mimic.

Each of the three has 3500 health and attacks by lunging or stomping on the player. Its stomp attack can travel through blocks. They will occasionally close themselves to prevent all damage.

In addition to natural spawns, the Hallowed Mimic can be spawned by placing a Key of Light in an empty chest, and the Corrupt Mimic or Crimson Mimic can be spawned with the Key of Night.

Dark Mage
Main article: Dark Mage

The Dark Mage is a miniboss that appears in the Old One's Army Event during wave 5 in Tier 1 and during waves 4 and 6 in Tier 3. The Dark Mage will float above the ground and will attack by hurling a magical ball of energy at the player, it can also summon skeletons and heal its allies by conjuring a large rune that provides healing.

Main article: Ogre

The Ogre is a miniboss that appears in the Old One's Army Event during wave 7 in Tier 2 and waves 5 and 6 in Tier 3. The Ogre attacks by swinging its club at its target or by jumping in the air and landing with a shockwave when in close range, it can also hurl a ball of snot at the target at long range.

Console Version

Main article: Ocram

OcramTrophy.png The Ocram's attack style is very similar to that of the Eye of Cthulhu. Like the Eye of Cthulhu, it charges repeatedly at the player while summoning servants. Additionally, it fires numerous red laser beams which spread out. The Ocram has in total 35,000 HP and after knocking its health down to halfway, it will (like most bosses) switch into its second mode, where it continues to summon servants, but will charge constantly and the laser changes to a blue, more damaging laser which spray out at an insane rate. Ocram also uses the demon scythe spell summoning several demon scythes at once doing a fair amount of damage. Souls of Blight are Souls dropped by Ocram. It would take 205 Souls to make all the relevant items. The Ocram needs to be defeated 7 to 14 times in order to craft all of the relevant items using the Souls of Blight, however, since it will always drop one piece of the console-exclusive armor, it means you will need 15-20 less souls saving you a few Ocram fights. As of console 1.2, it now drops its own trophy.

Main article: Arch Wyvern
Arch Wyvern

The Arch Wyvern is a type of Wyvern found in console Hardmode. With double the health of a normal Wyvern (8000HP) and a damage output of 70-90 damage, the Arch Wyvern is a fearsome foe. It can go through blocks, but if the character walks too far away from it the Arch Wyvern will despawn. Even though it has twice as much health as the regular wyvern it still has the same amount of drops.

3DS Version

Main article: Lepus
Lepus is the first 3DS-exclusive boss, secretly added in 1.1.8 and revealed in 1.1.91. It is summoned using a Suspicious Looking Egg, a drop from Diseaster Bunnies and Corrupt Bunnies. It has 2000 health and approximately 20 attack and 12 defense. It shoots eggs which spawn Lepus clones and Diseaster Bunnies. It is the only source of Greater Healing Potions in mobile Terraria, and it also drops items such as the Boots of Ostara and the Egg Cannon. Due to a bug, Lepus will also occasionally drop Souls of Might.

Main article: Turkor the Ungrateful
Turkor the Ungrateful
Turkor the Ungrateful is a Boss available during Thanksgiving. Its body is a cooked turkey on a plate, and its head is attached by a long, flexible spine. The head must be destroyed first, otherwise, the body will only take 1 damage per hit. Once the head is destroyed, the body is vulnerable to attacks for a short period, after which more heads grow.


  • Bosses will follow the character and kill the NPCs if they get close to them.
  • The Bosses' "roars" can be heard not only when they are summoned but also when they do an attack unique to them. (ex. When the Queen Bee charges from one side of the player to the other or when Skeletron spins his head)
