Terraria is a 2D sandbox adventure game where players venture across a vibrant yet dangerous world and face off against different bosses. Now many players might be wondering what the best boss order in Terraria is, and that’s exactly what we’ll be discussing in this guide. We will also sprinkle useful tips and tricks for defeating each boss mentioned below.
Each boss in Terraria is designed with a very open-ended design, meaning there are countless ways you can deal with them. You can choose the strategy according to your build and playstyle or try incorporating the ones we suggest in this article.
1. Eye of Cthulhu
The Eye of Cthulhu is probably the easiest boss you can defeat in the game because it is the first boss you encounter when you start a world. There are two ways that this boss can spawn, and the first way is naturally. When you reach 200HP, the eye gets a 33% spawn chance at night.
The second way is if you kill Demon Eyes and collect their lenses, you can take them to a Demon Altar and make a Suspicious Looking Eye. When you have this item, wait until nighttime and prepare yourself. Use the item and go right into the fight.
Moveset – The Eye of Cthulhu has some very interesting attacks. When he first spawns, he will fly all around you. Remember that he can fly through any object, so make sure you fight him away from your house, so he does not kill any NPCs. He then starts to fly toward you with swift attacks, and if he hits you, you will take damage.
Once you bring him down to about 50% health, he spins, and his lense breaks off, turning into a mouth with teeth. He starts attacking even faster and harder than he did before. You have to be careful in this phase because this is where most people die.
Rewards – When you defeat him in normal mode, you get 30-87 Demonite ore/Crimtane Ore, depending on what world you are in, 4 gold coins, and a chance to receive a trophy. In expert mode, you will receive everything from normal mode, plus the Shield of Cthulhu that lets you dash forward and give out damage.
Tips and Tricks – The best thing to do is once you load into the world, go mining and try to find a Gravitation Potion. Once you find it, go back to the surface and use it. It lets you control gravity and fly really high in the sky. Find a floating island and get a Starfury, and that sword can trounce the Eye of Cthulhu. Having the best food for yourself will also be beneficial.
2. King Slime
King Slime is also very easy compared to other bosses in the game, but what makes him so different is how you can spawn him. The first way is by making a Gold or Platinum Crown and combining it with 20 gels at a Demon Altar. The second way is when there is a Slime Rain, defeat 75 Slimes and he will be summoned.
Moveset – King Slime has a very basic moveset and only one phase. When you start to fight him, he will spawn out of thin air and start jumping everywhere. Once and a while, he will teleport to another spot, but that is the extent of his attacks.
Rewards – When he is defeated, you will have a chance to receive these things: Solidifier, Slimy Saddle, Ninja Hood, Shirt, and Pants, Slimy hook, Slimy Gun, and a trophy. Each item has a chance for you to get it, so don’t just rely on fighting him once. In expert mode, you get a special item called the Royal Gel that makes all Slimes in your world passive.
Tips and Tricks – A very easy way to defeat him is if you get some rope and place the rope very high in the air. Once done, get a gun or bow and reach the top of the rope. If you have placed the rope high enough, then you will be able to shoot him without him even touching you at all.
3. Deerclops
The Deerclops can be summoned in the Snow biome using the Deer Thing item. It is crafted from 3 Flinx Fur, 5 Demonite or crimtane Ore, and a Lens. You can also find him naturally at midnight during a Blizzard if you have 9 defenses or 200 health.
Moveset – He has a few ice-based attacks that you need to be careful of. He will smash the ground and send an ice spike wave toward you or throw ice spikes at you from a distance. Every so often, he will roar, and if you are caught in the radius, you will receive a Slow debuff.
Rewards – Defeating him will shower you with the following items; Deerclops Trophy and Relic, Bone Helm, Deerclops Eyeball, Lucy the Axe, Houndius Shootius, Pew-Matic Horn, and Deerclops Mask.
Tips and Tricks – You can use 50 to 60 Explosive Bunnies in a box to lay a trap for Deerclops before summoning. Once he is spawned, the trap’s damage can kill him instantly.
4. Eater of Worlds/Brain of Cthulhu
The Eater of Worlds/Brain of Cthulhu is a difficult but rewarding boss. You summon him if you go into the Corruption or Crimson, depending on what world you have, and break 3 orbs found in the underground area. Once broken with a hammer, the boss will spawn.
The other way is to collect Rotten Chunks or Vertebrae and create a boss spawner. A plus for destroying an orb is it allows a meteorite to fall somewhere in your world for extra materials.
Moveset – The Eater of Worlds has a very simple moveset. It flies through the ground like a worm enemy and tries to kill you with all its body parts. There are 50 segments that you must kill, and you can cut it in half, but you will have to fight multiple pieces.
Rewards – When you defeat him, you will get 50-100 Shadow Scales, 100-250 Demonite ore, Eater of Worlds Mask, Eater’s Bone, and a trophy. In expert mode, you will also receive a Worm Scarf, allowing you to have 17% reduced damage.
Tips and Tricks – A very easy way to defeat the Eater of Worlds is if you break one of the orbs and wait until a meteorite lands. Once it lands, find it and mine it all. You then can make a full set of Meteor armor and a Space Gun. The armor gives unlimited ammo to the Space Gun, and it can easily defeat the boss.
5. Queen Slime
Queen Slime can be spawned in the Hallow by using a Gelatin Crystal—if used outside the Hallow, nothing will happen, and the item will not be consumed. The crystal is consumed upon use, immediately summoning the boss. The Gelatin Crystal can be found in the Underground Hallow among Crystal Shards growing on Pearlstone and Pink Ice blocks.
Moveset – This boss’s first form is similar to the fight with King Slime, but she gets much more difficult in her second phase. Queen Slime is outfitted with wings that make her harder to dodge than her more ground-locked partner.
Rewards – After defeating her, you can get the following items; Queen Slime Trophy/Relic, Volatile Gelatin, Sparkle Slime Balloon, Gelatinous Pillion, Hook of Dissonance, Blade Staff, Crystal Assassin Hood/Shirt/Pants, and Regal Delicacy.
Tips and Tricks – Queen Slime herself has a relatively simple attack pattern. Half the threat comes from the minions she spawns, which can fill the screen with projectiles and quickly overwhelm the player. Killing or avoiding these should be the top priority. Invisibility Potions can decrease the spawn rates of other enemies and prevent the Heavenly Slimes from chasing after you.
6. Queen Bee
The Queen Bee is only found in one place and can’t be summoned with an item. It is only found in a beehive in the jungle biome. Once you find a beehive, go inside and find the larva sitting on a platform. All you have to do to summon her is if you go over to the larva and break it with your sword.
Moveset – The Queen Bee has a very weird moveset in that she flies through the walls and shoots stingers at you when spawned. She also spawns other tiny little bees that can get annoying if you are stuck in the hive’s honey. She also stops in the middle of the hive, and that is the best time to strike.
Rewards – When you defeat her, some of the best items you will receive are the Bee Keeper, Bee Gun, The Bee’s Knees, Bee outfit, Honeyed Goggles, and a trophy. In expert mode, you will get a Hive Pack, which allows all your Bee weapons and equipable to be boosted by 30%.
Tips and Tricks – The best way to defeat her is to use your Space gun again. This time, if there is a lot of honey in the beehive, make a bridge over the honey, so you don’t get stuck in it. After you make the bridge, summon the Queen and use your Space Gun to do a lot of damage to her.
7. Skeletron
Skeletron is found by going to the Dungeon opening somewhere in your world. Every world is randomly generated, so there is no specific location where it is. Once you find it, a Clothier will be outside, wanting you to eliminate his curse. If there is an option to do it, Skeletron will spawn and start attacking you.
After you beat him, the Clothier will spawn in a house as an NPC, and if you find the Clothier Voodoo Doll and kill the clothier, Skeletron will spawn again, but it has to be at night.
Moveset – His moveset consists of his head and two hands flying through the air and hitting you with successive attacks. You can defeat each of his hands and leave only the head, which does make for an easier fight. His head spins around and follows you, so you can get caught in a combo if you are not careful.
Rewards – You don’t get as much from him as you do other bosses, but defeating him gives you access to the dungeon with tons of different weapons and enemies. You get a Skeletron Hand and Mask, a Book of Skulls, and a trophy. In expert mode, it gives you a bone glove that allows you to throw bones for massive damage.
Tips and Tricks – If you get Spiky Balls from the Goblin army and throw them all over the arena where you fight him, they will slowly damage him while you fight him. The Space Gun is also a good weapon against him if you have good aim.
8. Wall of Flesh
The Wall of Flesh is the last boss before you get to Hardmode. The way you summon him is to find a Voodoo Demon and kill it. A Guide Voodoo Doll will fall from the tail, and you can pick it up. Once you have it, throw it into the lava in the underworld. It will kill the guide and summon the Wall of Flesh.
Moveset – The Wall of Flesh is very different from any other boss in the game because it does not follow the player. It spawns and traverses the entire underworld, slowly crossing the entire thing. It also shoots lasers at you and sends little worms after you to do even more damage.
Rewards – You can get a lot of stuff from beating the Wall of Flesh: the Breaker Blade, Clockwork Assault Rifle, Laser Rifle, 4 different Emblems, a mask, and a trophy. The Pwnhammer is always received because you need it to break Demon Altars for Hardmode. In expert mode, you are given a Demon Heart, which can give you an extra equip slot for your character.
Tips and Tricks – The best way to beat the Wall of Flesh is to either build a bridge across the underworld or get an Obsidian Skin potion and a Feather Fall potion to maneuver through the area easily. Your best bet is to make a Pheonix Blaster from Hellstone and use Meteor Bullets to get maximum damage out of it.
9. The Destroyer
The Destroyer is the first Hardmode boss and is the first real challenge for bosses in the game. It is a mechanical version of the Eater of Worlds, except with little robots shooting lasers at you along with it. It can only be summoned by a boss summoning item and is not hard to get.
Since the Destroyer is the easiest of the three mechanical bosses, it is best to farm him until you get enough good gear to fight the next two. Don’t worry about how hard he is; once you get how to beat him down, it will be easy the next time you do it.
Moveset – It has essentially the same moveset as the Eater of Worlds except that it has a shared health bar and can’t be broken into segments. It flies through the ground and shoots lasers at you. Little probes float around and can give you hearts when killed to aid your fight.
Rewards – When you defeat it, you will get 20-40 Souls of Might, 15-30 Hallowed Bars, a mask, and a trophy. Very rarely can you get the Horned God Robe. In expert mode, you will receive a Mechanical Wagon Piece, which you can later use to make a Mechanical Cart.
Tips and Tricks – The best way to defeat the Destroyer is to summon a Hallowed Mimic and defeat it until you get the Daedalus Stormbow. Once you have it, stock up on Jester Arrows and make a boss arena with wooden platforms. You must fly around the arena with wings and shoot the Destroyer with the bow.
10. Skeletron Prime
Skeletron Prime is the second mechanical boss and is much harder than the Destroyer. It has four arms with many different weapons instead of the two which Skeletron has. Skeletron damages the player if they get caught among all the arms and are constantly being flung around in every direction. It can be summoned only by a boss summoning item.
Moveset – As I said before, he has four arms that can destroy you if you’re not careful. Each arm has a different weapon: a cannon, a vice, a saw, and a laser. You can destroy the arms, making it easier to destroy all four. All that is left is his head, which can still damage the player when it spins.
Rewards – When you defeat him, you get 20-40 Souls of Might, 15-30 Hallowed Bars, a mask, and a trophy. Rarely can you get a Horned God Mask. In expert mode, you get a Mechanical Battery Piece, which you also use to make the Mechanical Cart.
Tips and Tricks – Although it is time-consuming, focusing on his arms is your best bet because it makes life so much easier when you only have to worry about his head. Using a Golden Shower will do extra damage because of his high defense; just make sure he gets close enough for you to hit him.
11. The Twins
The Twins are the hardest of the three mechanical bosses because they are faster and do more damage than the others. They are essentially like two Eyes of Cthulhus connected, and one shoots lasers while the other shoots poison. The twins do massive damage and are very hard to hit with certain weapons.
They can only be summoned by a boss summoning an item, and the item can be found or crafted. Numerous times, I killed an enemy, and I found a summoning item on the ground.
Moveset – Their moveset is simple but difficult to master. When the fight starts, they both come out just like the Eye of Cthulhu, except they do a lot more damage. as they fly toward you, they shoot lasers and poison at you. When they reach 50% health, they lose their lenses, grow teeth, and then start dive-bombing you.
Rewards – When you defeat them, you will get 20-40 Souls of Sight, 15-30 Hallowed Bars, a mask, and a trophy. Very rarely will you get the Horned God Boots. In expert mode, you will receive a Mechanical Wheel piece, and if you beat all three mechanical bosses in expert mode, you can finally make the Mechanical Cart.
Tips and Tricks – If you have a magic weapon that deals with curses, then that is an easy way to defeat them. Also, if you have a Megashark with Cursed Bullets, that can do major damage to them depending on if you have enough bullets to beat them.
12. Plantera
Plantera is one of those weird bosses in the game that is very difficult unless you know what you’re doing. The only way to summon Plantera is to find a Plantera Bulb somewhere in your jungle biome. The only way for you to find one of these is to defeat all three mechanical bosses in Hardmode.
Once you find one of these bulbs, you will want to break it with your pickaxe. After you have done that, Plantera will spawn in a matter of seconds. You will know when a Plantera bulb can be found because a prompt says that the jungle is changing.
Moveset – Plantera moves all over the place with her vines, and it can be kind of Closter-phobic when it comes to space in the jungle. You will want to open up the area where you found the bulb so that you don’t get stuck when the boss gets spawned. As it moves around your arena, it is going to shoot little seeds at you, and it will do damage if it hits.
At 50% health, the second phase is a lot harder than the first because its speed and damage are doubled. You will know when the second phase happens when its mouth opens up a lot more than it is, and it starts speeding up.
Rewards – When you defeat Plantera, you will receive a Temple Key, Pygmy Staff, Grenade Launcher, Venus Magnum, Leaf Blower, Flower Pow, Wasp Gun, Seedler, Thorn Hook, a mask, and a trophy. In expert mode, you will receive a Spore Sac, which spawns spores over time that damage enemies to the max.
Tips and Tricks – Your best bet is to open up the biggest area around the bulb, so you have room to fight it. The bigger the room, the better. Make sure you put torches and platforms all over the room and throw Spiky Balls all over the place to do extra damage. Use a gun or a bow with Meteor Bullets to do extra damage to it.
13. Golem
Golem is a very fun boss to fight and is only found inside the Jungle Temple of your world. The only way to get into the temple is to beat Plantera and get the Temple Key. Once inside, make your way to the end of the temple and get the batteries from the chests you find. Once you reach the altar, activate it, and Golem will spawn immediately.
Moveset – His first phase starts with punching you with his fists and jumping at you. Watch out for his arms because they can do some massive damage to you. His second phase is the hard part, though. After you defeat his arms, his head pops off, shooting lasers at you. His body keeps jumping on top of you at the same time.
Rewards – When you beat Golem, you get the Stynger, Possessed Hatchet, Sun Stone, Picksaw, Golem Fist, a mask, and a trophy. You also get 4-8 Beetle Husks which you can use to make very strong armor later in the game. In expert mode, you get a Shiny Stone which makes health regeneration faster when not moving.
Tips and Tricks – Using Poison Bullets in a good, damaged weapon is a very easy way to defeat him and will do more damage over time. You can get him stuck when he spawns, so he can’t jump onto your head and do extra damage.
14. Duke Fishron
Duke Fishron can be summoned by fishing in the ocean with a Truffle Worm as bait. Once you throw the hook in the water, in a few seconds, he will spawn. That is the only way for you to summon him. He looks very different from the other bosses because he resembles a walrus with wings.
Moveset – His moveset is very hard to keep up with because everything is happening simultaneously. His first stage starts with him lunging at the player, then shooting damaging bubbles at you. He then spawns tornados with sharks that can catch you up and damage you.
His second phase is even harder than the first because the damage from everything is boosted. His third stage changes everything because he still attacks, but you can only see his glowing eyes.
Rewards – When you defeat him, you get Fishron Wings, Tsunami, Bubble Gun, Flairon, Tempest Staff, a mask, and a trophy. When defeated in expert mode, it also gives you a Shrimpy Truffle, a mount that can glide and hover indefinitely.
Tips and Tricks – The best thing to do is to get a blessed apple, a unicorn mount, and make a bridge over the whole ocean. The mount allows you to easily run back and forth on the bridge while shooting at the boss.
15. Lunatic Cultist
The Lunatic Cultist is the boss right before the final boss. He is not that hard once you understand how his fight works, but very difficult if you are going in for the first time. The only way to activate the boss fight is to defeat Golem and then wait a little while.
Some cultists will eventually spawn in front of the dungeon where you defeated Skeletron. All you have to do to start the fight is to kill all the Cultists in front of the giant gold sphere.
Moveset – Once the Lunatic Cultist is spawned, he will do 1 of 3 attacks. He will either throw fireballs at you or big chunks of ice. The Cultist will then shoot bolts of lightning at the character. He then summons duplicates of himself, and if you kill a duplicate instead of hitting him, a Wyvern will spawn and make the fight harder. He cycles through his attacks until you finally defeat him.
Rewards – When you defeat him, you will get an Ancient Manipulator, a mask, and a trophy. You don’t get much from him after you kill him because the Lunar Events will start occurring once you kill him, which is how you spawn the final boss.
Tips and Tricks – Avoid defeating this boss if you are not ready to start the Lunar Events because they start right after you defeat the Lunatic Cultist. The best thing you can do to prepare for this fight is to get a good gun with Chlorophyte Bullets to home onto the boss. Also, you should know the difference between his duplicates and the actual boss to make it easier for you in the long run.
16. Mechdusa
The Mechdusa is a hidden boss and is a fusion of the three Mechanical bosses i.e., the Twins, The Destroyer, and Skeletron Prime. To summon this boss, you need to follow some complex steps.
You must have the Mechanical Eye, Mechanical Skull, and Mechanical Worm items on you. Then create a new world with this seed; “getfixedboi“. Use a Mythril Anvil or Orichalcum Anvil to combine the previous three items and create Ocram’s Razor. Use this item to summon the boss.
Moveset – It has all the attacks of the aforementioned mechanical bosses and has the highest HP of any boss in the game. You are essentially fighting all three bosses simultaneously and will have to take out each while wary of the incoming attacks slowly.
Rewards – Defeating it will reward you treasure from the respective boss and the Waffle Iron, a new weapon from the 1.4.4 update. Trophies from all three mechanical bosses will be rewarded.
Tips and Tricks – Mechdusa functions as a fusion, inheriting all bosses’ abilities: Skeletron Prime attacks using its arms, The Twins attack with their respective patterns, and The Destroyer shoots lasers. Like other multi-segmented enemies, each mechanical boss has its health bar. Initially, The Destroyer follows the movement of Skeletron Prime. Defeating Skeletron Prime separates them and allows The Destroyer to move around freely.
17. Empress of Light
This optional post-Plantera boss can be fought by killing a Prismatic Lacewing in the Hallow biome. They spawn at night between 7:30 PM and 12:00 AM. You can fight her in day time, but she is considerably stronger and can kill you in one shot.
Moveset – The boss has this exact deadly moveset; Prismatic Bolts, Dash Attack, Sun Dance, Dash Attack, Everlasting Rainbow, Prismatic Bolts, Dash Attack, Ethereal Lance, Dash Attack, Everlasting Rainbow. She is the fastest boss in the game and will always catch up to you in the blink of an eye for her next attack.
Rewards – If you are ballsy enough to fight and defeat this boss during the day, you will be rewarded with one of the best weapons in the game, the Terraprisma. Other amazing things you can get from killing her are; Starlight, Kaleidoscope, Eventide, Soaring Insignia, Empress of Light Mask, and Empress Wings.
Tips and Tricks – The Empress of Light’s moves can easily trap you. Therefore, a wide arena is strongly suggested for the fight against her if you don’t possess an infinite-flying mount. The arena should span as far as your Hallowed biome can be, and you should make it longer if your hallowed biome isn’t large enough. 3-5 rows of platforms separated 15-25 tiles from each other will do.
18. Moon Lord
Moon Lord is the final boss in Terraria. He is the most challenging boss and the hardest to get to in the game. The only way to fight him the first time is to beat the 4 Celestial towers after beating Lunatic Cultist. He is very challenging because he follows you around everywhere you try to go.
Moveset – He has a very different moveset because of where he attacks. He can attack from his hands, forehead, chest, and eyes. Each attack can have a devastating blow if you get hit; it is very easy to die. He also shoots lasers at you and sends little green eyeballs after you to deal extra damage. Understanding his moves is key to beating him.
Rewards – You can get many things from the Moon Lord, and those are 70-100 Luminite, Portal Gun, Meowmere, Terrarian, S.D.M.G., Star Wrath, and Last Prism. In expert mode, you will receive 2 items for beating him. The first is a Gravity Globe, which is an unlimited Gravitation Potion. The second thing is a Suspicious Looking Tentacle which is a pet.
Tips and Tricks – The best way to defeat the Moon Lord is to have a flying mount and a good gun with Chlorophyte Bullets to home in on the parts that need to be shot. Also, you need some good armor too because of the damage output he has. There are many things to do after defeating Moon Lord in Terraria. So, get ready for even tougher adventures!
