Top 10 Hardest Terraria Bosses


The Top Ten

1 Duke Fishron Duke Fishron

I've fought him three times now and I had the Solar Eruption AND full Solar Armor on me. I also had the Cosmic Car Key but even with that he is just too fast to get around. Every attack is simple to get around but the dashes are simply unfair. The Moon Lord is a breeze compared to this guy.

He is simply too fast. Use the Ninja master gear to dodge him, but still the tornadoes are so fast you can barely dodge them. It's hard just to spawn him in, as you need the rarest fish food in the game, a truffle worm.

I think he is the hardest but I'm in the point of the game where I'm impossible to beat.

At the stage of the game you usually try to fight it most players are very underpowered and are not prepared to farm for the truffle worms.

2 Moon Lord Moon Lord

Moon lord, in my opinion, is incredibly easy, and I beat him first try. The fight was extremely underwhelming, and after defeating him, I felt as though he wasn't actually the last boss, which unfortunately, he is.

Guys, I think your delirious, this is THE LAST BOSS IN THE GAME. All the others I could (if you could summon them) beat them post easy mode. Learn how to play this game.

Dude requires a lot of preparation before hand and once you beat the last pillar you got a minute to recooperate from the battle not enough time in my opinion best way to kill him is ironically with ducks so have a duck statue turn it on and well he breaks literally

He is the best it took me 50 tries with vortex armor from my friends and also them helping me..

3 The Twins The Twins

Who ever says this monster is easy is WRONG I easily beat skeleton prime I beat skeleton prime then destroyer of worlds (the robot worm) and I STILL lost to this thing also dudes get good go solo don't go double teaming bosses I feel it takes out the challange of boss fighting

The Twins is easy I beat him before the destroyer or skeleton prime

Me and my bro fid it instantly

While somewhat hard, I think the destroyer goes in this place, or maybe plantera as the movement of the twins is highly predictable while the destroyer and plantera are mor erratic and therefore harder

4 Plantera Plantera

Got Terra Blade and STILL cannot defeat it WHY?! I am at somewhere around 80 defense AND I have got full armor SO WHY?!?!?!

It is a easy boss scrubs just get good

This boss should be in second. I haven't even beaten it yet

This is always the hardest boss for me, I died 5 times with turtle armor before killing it

5 Eye of Cthulhu

I have full beetle armor, the phantasm, the stardust dragon, and the solar eruption. However, I am still not able to defeat him yet!

This boss should be easy when you join hard mode. If you are a beginner or started a new character it would be best to fight king slime before you fight the eye of cthulhu. It is recommended to have a musket with a couple hundred bullets and at least 10 defense points.

To easy beat him with a gold broadsword and silver armor

I play on mobile and only need emerald staff and silver armour to defeat

6 Skeletron Prime

This is skeletron PRIME, not normal. He is not killable with a waterbolt and shadow armour.

Are you kidding me Skeletron was the easiest boss! It took me about 1 minute to defeat him!

I think you need a shadow armor and a demonic water bolt

Well, this took a long time to defeat! I spent 2 days devising a plan to beat him and it still wouldn't work. I killed the twins for a practice round, because they are pretty easy. I killed him AFTER my friend and I beat the frost moon. I felt weak compared to terraria, but I know that a lot of others feel that way also.

7 King Slime

Bruh this is easily the hardest boss in the game. I think it is literally impossible to beat and definitely needs to be rebalanced. If it is even beatable does anyone have any tips on beating this monstrosity.

Way to powerful I have the last prism and nebula armour and I still can not defeat this overpowered boss it is so hard.

This is literally the easiest boss in the game why is this here

Build a rope high to where he can't reach you then shoot him up

8 Wall of Flesh

Well, I beat him with 11 golden hearts and a titanium sword, not as hard as I thought.

Bone javelins with jungle armor is what I beat this man in expert with

Takes about 10 hits with the Terra Blade, pretty easy.

Screw him with the Molotov cocktails

9 Ocram

I died to ocram before 1.3 update came out

Using the razor blade typhoon with no armour you can win easily - BelganIPancake

Dude you just gotta get the right armor and gold hearts and you can kill him with a wood sword

Noob I destroyed him with 36 defense SUCKERS

10 Golem Golem

Whilst Golem is easy, King Slime is miles easier.
For starters, King Slime is the very first boss you fight, whilst Golem is one of the last bosses you fight.

Then there's the fact that King Slime can be cheesed by building 30 Ropes up into the sky and throwing shurikens down at him. - IDunnoWhatToNameMyself

Golem is the most pathetic boss ever, You can just put him in a box and boom, you win.

This is the easiest boss ever. Lock it in a box, set up traps, and its dead.

I agree with all the others


The Contenders

11 Green Slime

I honestly don't know how to fight this boss. I fought it with full vortex armour, a coin gun shooting millions of plat coins, and a S.D.M.G, but before I died, it came in my mansion, killed all my NPCs, raided all my chests, and knocked the whole thing over. If anyone knows how to hack and kill it, please come in my world and reduce it's 100,000,000,000,000,000,000 health to zero. It's to OP, please nerf.

This isn't a boss it's the weakest monster in the game (I'm pretty sure everyone who is saying that it's hard is joking)

Literally impossible, I even tried using cheats but there's no way to beat this beast

This isn't even a boss! It is the weakest enemy in game!

12 Brain of Cthulhu

How is this easier than a green slime? - computerfan0

How do you defeat thi? - stumpface

The brain of Cthulhu was so easy that I could beat him with wood gear

He's ez on normal mode but on expert mode he's A NIGHTMARE

13 Lunatic Cultist Lunatic Cultist

Lunatic cultist is a breeze with vampires knives, I accidentally summoned him the first time and still won easily

Pretty hard I would think 5 or 4 but yea still decently hard

Really deserves to be under Duke and Moonlord in terms of difficulty, but this guy definitely at least deserves the number 3 spot. If you don't have a proper DPS weapon for the cultist himself as well as a decent weapon that can simultaneously attack the segments of the dragon he conjures, you'll find yourself gobbled up pretty quick.

I was using terra blade not even 10,000 down I died

14 Eater of Worlds

It was sooo easy I just used my enchanted boomerang

I summonened him in jungle and a drop from that orb was super good aginst him, it summoned a weird vine staff

That is ez! I was able to kill him with 2 of my weapons:with shurikens and with the meatball. You just think it’s hard lol

I literally just swung my sword and took it out first time. Loss 1 heart

15 Queen Bee

This is a hard boss of it making her defenses stronger and it's pretty hard

I defeated 10 in 1 day!

I beat her 4 times in one day

Easy man

16 The Destroyer

Pretty hard boss but he is very easy compared to the other two mechanical bosses

Me and my friends kept hitting him. Got our inventories full of headstones, died a lot, but he died too

I tried hardcore mode and wanted to defeat the mechanical bosses and you know what? munch munch *DEAD*

By far the easiest of the mech bosses. This, then skeletron prime, then The Twins.

17 Dungeon Guardian

Why is he not number 2 (number one would be moon lord who isn't a troll boss)

He should definitely be number 1or2

He is so strong he should be number one I have never kill him

But I thought it was the hardest
As it has a lot of defense
And one shot you

18 Skeletron

In normal mode he's a joke. In Expert? It's a nightmare. - iDontCareFAM

So Easy as soon as you have at least gold armour and a bed close by it's so Easy

Hard as hell in expert mode

Hardest in expert mode

19 Supreme Calamitas

Very hard boss

This is supposed to be for unmodded, but since it's here...

What this isn't even modded!

If modded bosses can be on the list then scal easy number 1 but if not then why is he here

20 Slime

What the beep this is just so eazy its not even a boss, all you need is a weapon that does 1 damage. Whoever can't beat this is a noob no even worse a failure.

I had Terra Blade, and Full Titanium Armor but ONE HIT and I was wasted

It killed me one hit with full stardust stuff and an invincibility mod with terra blades

Me and my friend played through the whole game and it was easy. We killed Duke Fishron and Moonlord first try. At the end we had solar armor, Terra blades, and even the last prism. We also had a pretty legit castle base with a lava pit and all the npcs. I thought we beat the game. That was until this boss came out of a bush and flew into our castle and killed me in one hit within a single frame. I couldn't even react in time. My friend managed to get 1 damage out of its 700,000,000,000 health before dying the next second. It left our castle destroyed and everything was on fire. It also killed all of our npcs before flying away. If you see this boss run for your life, IT IS IMPOSSIBLE!

21 The Lunar Pillars The Lunar Pillars

The nebula pillar is somewhat easy but the solar pillar is INSANE took me 7-15 deaths with post moon lord weapons+UFO

They are easy until you get to the last one and realize that the moon lord is being summoned and you don't have an arena

Pretty hard and annoying to try and kill

22 The Devourer of Gods

To easy I killed him in one hit

He is my favorite Boss. though he might be hard.



23 Lepus (Mobile Version)

Easier than green slime

Kinda hard.

Just get spider staff and like the fiery greatsword, ez pz. Literally took out 3 times in a row.

He’s respawns because he lays eggs I hate lepus

24 Harpy Feather


I like trees

Harpys are hard and what are harder is is the Harpy's feathers and they "TIKILL" get it? ? tikill

so hard
