Terraria Summoning All the bosses

Terraria Summoning All the bosses guide will show you how to summon all the boss in Terraria.


King Slime

King Slime is a giant blue slime with 2,000 / 2,800 / 3,570 health. It is summoned with a Slime Crown, or after killing 150 (75 if he has already been killed) slimes during a Slime Rain, or can also rarely appear in the outer thirds of the map completely by itself. As with all enemies that can spawn naturally, the King Slime has a better chance of spawning while standing near a placed Water Candle or while under the effects of a Battle Potion.

How to Summon:

Summoned with a Slime Crown
Eye of Cthulhu

The Eye of Cthulhu is a huge eyeball with 2,800 / 3,640 / 4,641 health. It has a 1/3 (33.33%) 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 can also be summoned using a Suspicious Looking Eye at night. If not defeated by the player by the end of the night, it will travel upwards and despawn. This is generally the first boss a player must face. It travels through blocks, and spawns Servants of Cthulhu.

How to Summon:

Summoned with a Suspicious Looking Eye
Eater of Worlds

The Eater of Worlds is a colossal worm with 10,050 / 15,120 / 19,224 health in total on the Desktop version and Mobile version, and 7,500 / 10,500 health on the Console version, Old-gen console version, and 3DS version. It awakens after every third Shadow Orb is broken or after Worm Food is used. Shadow Orbs are found in the Corruption chasms, surrounded by Ebonstone, which requires a pickaxe with 65% pickaxe 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 or explosives. The Eater of Worlds can only be summoned in worlds containing Corruption, and can be summoned at any time of the day. If it manages to escape the Corruption, it will flee and disappear.

How to Summon:

Summoned with Worm Food
Or by breaking 3 Shadow Orbs.
Brain of Cthulhu

The Brain of Cthulhu is a large, flying brain with a mere 1,000 / 1,700 / 2,167 health, giving it the lowest amount of health out of any boss. It spawns once for every third Crimson Heart that is broken or immediately after a Bloody Spine is used. Crimson 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. It can only be summoned in the Crimson, but at any time of day.

How to Summon:

Summoned with a Bloody Spine
Or by breaking 3 Crimson Hearts.
Queen Bee

Queen Bee is an enormous bee with 3,400 / 4,760 / 6,069 health. She is summoned by destroying her larva, encased within the walls of Bee Hives located in the Underground Jungle. She can also be summoned by the use of an Abeemination anywhere in the Jungle biome. She is the only source of Bee Wax in the game. Queen Bee is immune to knockback.

How to Summon:

Summoned with an Abeemination
Or by breaking its Larva

Skeletron is a large skeletal head with 4,400 / 8,800 / 11,220 health and two hands. It is summoned by speaking to the Old Man NPC at the entrance of the Dungeon and activating his curse 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 usually kill the player in one hit. It will then despawn.

How to Summon:

Summoned by killing the Clothier with a Clothier Voodoo Doll equipped
Or by activating the Old Man’s curse.
Wall of Flesh

The Wall of Flesh is a towering wall that spans the entire screen height. It has 8,000 / 11,200 / 14,280 health. It is summoned by throwing a Guide Voodoo Doll into a pool of lava while the Guide is alive. It is the final boss of pre-Hardmode, because defeating it will irreversibly enable Hardmode in the world. It can drop several powerful items, one of them being the guaranteed drop Pwnhammer which can be used to break Demon Altars or Crimson Altars in order to spawn various game-advancing Hardmode ores.

How to Summon:

Summoned by throwing a Guide Voodoo Doll into lava

Queen Slime

Queen Slime is a giant slime with 18,000 / 28,800 / 36,720 health. She is available to battle at the start of Hardmode, and is summoned from Gelatin Crystals in the Underground Hallow. She is an optional boss fight and is a small gap to challenge before facing the mechanical bosses, warranting equipment upgrades and other items. There is a very strong resemblance to the pre-Hardmode King Slime, and is one of two Hallowed bosses featured in the game. As she takes damage she spawns Crystal Slimes, Bouncy Slimes, and Heavenly Slimes to aid her. While her first form is straightforward with attack patterns similar to that of King Slime’s, the second phase poses much more of a threat as the boss begins to fly in the air, shooting projectiles from above.

How to Summon:

Summoned with a Gelatin Crystal
The Twins

The Twins are a pair of cybernetic Eyes of Cthulhu. They exist as two individual entities, known as Retinazer and Spazmatism, with the former having 20,000 / 30,000 / 38,250 health and the latter having 23,000 / 34,500 / 43,987 health. The Twins are summoned using a Mechanical Eye at night. It is worth noting that they will gain defense in their second forms, unlike the Eye of Cthulhu.

How to Summon:

Summoned with a Mechanical Eye
The Destroyer

The Destroyer is a colossal mechanized Eater of Worlds with 80,000 / 120,000 / 153,000 health. It is considered the easiest Hardmode boss by many players, despite having the second-highest health. Although it is similar to its pre-Hardmode counterpart, the Eater of Worlds, it has some key differences: it will not divide into smaller segments, will shoot lasers from its body if space is available, and will deploy Probes to attack once a segment is destroyed.

How to Summon:

Summoned with a Mechanical Worm
Skeletron Prime

Skeletron Prime is a weaponized mechanical variation of Skeletron, with the head alone having 28,000 / 42,000 / 53,550 health. Instead of two hands, it has four limbs – a vice, laser gun, saw, and cannon. With the head and all limbs combined, Skeletron Prime has 59,000 / 88,500 / 112,836 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 it can only be summoned at night. It is more mobile than its predecessor, and it regularly flies off-screen, making targeting more difficult. It is also worth noting that when its head spins, its defense increases, unlike Skeletron, whose defense is dropped to 0 when spinning.

How to Summon:

Summoned with a Mechanical Skull

Plantera is an enormous flower with 30,000 / 42,000 / 53,549 health. She is awoken by destroying a Plantera’s Bulb, which is found in the Underground Jungle after defeating all three mechanical bosses. If the player exits the Underground Jungle, Plantera becomes “enraged”, gaining a significant boost to her stats.

How to Summon:

Summoned by destroying a Plantera’s Bulb

Golem is a large boss with a combined total of 39,000 / 58,500 / 74,586 health. It 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.

How to Summon:

Summoned by using a Lihzahrd Power Cell at a Lihzahrd Altar —>

Empress of Light

The Empress of Light is a Hallow-themed boss with 70,000 / 98,000 / 124,950 health. She can be summoned from killing a Prismatic Lacewing, and is one of two Hallowed bosses present in the game. This boss is meant to be a small gap in between Plantera and Golem, but can be fought later or skipped altogether, as it is an optional fight. However, if the player fights her the moment she is available, they will face a major difficulty spike and numerous attack patterns. This boss can also be fought in the day, which will make her “enraged”, greatly increasing her attack damage to an instant-kill, but will drop the Terraprisma once 100% of damage is dealt during the day.

How to Summon:

Summoned by killing a Prismatic Lacewing
Duke Fishron

Duke Fishron is a mutant shark-pig-dragon hybrid with 50,000 / 60,000 / 76,500 health. He is summoned when a Truffle Worm is used as bait for fishing in the Ocean.
In his first stage, Duke Fishron will attempt to ram the player five times before either firing explosive bubbles or summoning Sharknados. In his second stage, Duke Fishron gains glowing eyes and a boost to attack and defense. Although his ramming attacks remain the same, instead of shooting bubbles directly at the player, he 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.

How to Summon:

Summoned by fishing in the Ocean biome with the Truffle Worm as bait
Lunatic Cultist

The Lunatic Cultist is a comparably small boss with 32,000 / 40,000 / 76,500 health. It is summoned by killing the four cultists, which reside at the entrance of the Dungeon after Golem is defeated. When the Lunatic Cultist is defeated, the Lunar Events will begin.

How to Summon:

Summoned by killing all the Cultists at the Dungeon entrance
Moon Lord

The Moon Lord is the final boss of Terraria, and drops a majority of the endgame items, such as the Meowmere. It also drops Luminite, an ore used to craft many endgame armor sets and tools. It is summoned by defeating all four of the Celestial Pillars from the Lunar Events, or by using a Celestial Sigil. It has a combined health of 145,000 / 217,500 / 277,311, the most health of any boss in the game.

Moon Lord has two hands and a head which must be killed by attacking the eyes on them, and when killed will release invincible True Eyes of Cthulhu. When the three eyes are destroyed, the Moon Lord’s core opens up on his chest, which must then be destroyed to defeat the boss.

How to Summon:

Summoned with a Celestial Sigil or by defeating the Celestial Pillars
