Top 10 Hardest Terraria Bosses


The Top Ten

1 Duke Fishron

Once I had played terraria for 1-3 years, I had the best gear in the game, and I just farmed this guy for wings to give to my friends.

You are right duke fishron is hard to beat and I can't beat him I tried the slime hitting you first and dodging his attacks

He kills me so much. If I could vote for 2, my second choice is the moon Lord. That stupid phantasmal death Ray.

He is so easy
He should be second

2 Moon Lord

He should be the first, I needed help from 2 other people to beat him, I have the full chlorophite armor, demon wings and some extra stuff for extra defense, I have solar eruption, daybreak, and the stardust dragon staff. I still needed those 2 people to beat him, even though I had all of these items.

He should be first. I have 68 defense and nights edge and I barley even got him to 3/4 health.

He's considered the final boss and is known to take health from the player and giving it to himself

I definitely think that he should be first.he could one-hit K.O. most players. Has most health and does most damage(in the long run).

3 The Twins

Hardest mech boss by far. Some people think that skeletron prime, or even the destroyer is the hardest, but the other two are relatively easy with a good strategy. With the twins, you need quick reflexes, precise aim, high mobility, strong weapons and armor, lots of buff potions, a carefully thought out arena, powerful accessories, the best modifiers, a bit of luck and a lot of practice. Doesn't help that you HAVE to actually fight this boss to progress through the game. Still a fun and very creative boss and he remains a fun boss to fight post-plantera due to his difficulty level.

The twins are pretty hard because I had full titanium armor and I was at 2 hearts after I defeated him but he still is kinda eazy

I killed the twins easily, in my opinion the destroyer is the hardest mech boss

I'm at destroyer but still the twins as I like to call jacksepticeye and markipeye.

4 Plantera

It is so hard the first time you face it if you don't have turtle armor and I've killed around 30-50 turtle and not gotten one turtle shell. - Incontrollable9_YT

Use teleporter on 2 sides of an arena and make a wall of any block to block mobs from spawning in on the side of the wall. You can then shoot it with a bow or gun whichever. Add campfires and heart lanterns. I could barely beat it this way!

The spikey balls that's why

Plantera is hell I find it harder then dukefishron it about time I show that supid plant a lesson or two

5 Skeletron Prime

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.

None of these are hard but come on queen bee at 10 are all voters retarded

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

I thought this boss would be hard so I put on the best armor and it couldn’t do any damage to me

6 Golem

How is he on here? He's one of the EASIEST bosses in Terraria. I beat him, no problem.

I have dragon armour and the terra blade and I still can't take him out when everyone says he's easy. I got up to level 10 with the pumpkin moon but I can't beat him?

He is hard because he shoots eye beams that do a lot of damage that almost kills me and I have 31 defense.

I found the golem temple and I couldn't find a way to get in I try to mine with the monten place I fell I don't know what to do """""

7 Lunatic Cultist

I handled this one very easily why my class is mage lol twins are harder than him speaking of which the twins summoner weapon vs the twins boss!

I think he kinda buff in my game, I've tried to beat him with my mage easily destroy

What? Why is he so low on the list? Golem plantera and twins were super easy and I did them all on my 1st try except this one... Am I doing something wrong?

I have almost 100 defense+Terra Blade+Cthuhlu Yoyo+Cursed Hatchet and he still wipes the floor with me.

8 Wall of Flesh

This boss is so easy I took him down with my friend in less then 20 second with my friend and we both hade around 25 defense I only hade the great sword and he had the true nights edge

He was so easy I had a physician skull water walking boot combo and had ended up with a glitch world where I went above 0 level in the dungeon before killing skeleton and found a rainbow gun in a normal chest took me 10 seconds.

Wasn't that hard, even with just a Nights Edge and a full set of Meteor Armor

I took him down in less than 5 sacks with bloody meowmere SUCKERS

9 Eye of Cthulhu

Eye of Cthulhu was pretty easy, if I beat it I get some red and black ore (i already wasted it on a sword and bow ) that I found in caves. I got somewhere about 24 or less ores. But it was a little annoying since he goes up into the air and I am horrible with the diamond staff so I just waited to use my rainbow claws and I killed him. Took me a total of 2 minutes.

Best strategy is to use the sawtooth shark for first form cause the minions die quick then at least a platinum sword for final form

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

The eye of chtulhu was the easiest boss I've fought!

10 Ocram

With complete turtle armour the Terra blade wings and a twenty by twenty box around you he's easy I've beaten him 13 times and I've spawned him 13 times so...

Ocram is the hardest host ever even ice rod and turtle armor can't work

Pretty hard boss scary too but bit to easy on this list here

He's strongman

The Newcomers

? Rainbow Slime

This is not a boss and while it does have a bit more health you should be able to take it out

Is this easy? Is it hard? Who knows? - oofnugget-boi

The Contenders

11 King Slime

People are RETARDED! "I beat him in 20 seconds, and all I had was end game weapons and armor, fighting a pre-hard node boss! ". This should be for what you WOULD have at a certain stage of the game that the boss is found!

This is on the wrong list, people. - LordDovahkiin

I'm guessing he is the easiest boss in Terraria.

Too easy take this off

12 Brain of Cthulhu

Ez it was so easy and not that powerful I didn't even have the first row of red Hearts completed and I still beat him with a starfury so he should be lower than this

13 The Destroyer

Pretty easy, as long as you know how to beat this dude its easy. But I did fail like 2-5 times though

Destroyer is easy. - LordDovahkiin

The other mechanical bosses are easy in comparism skeletron prime is predictable the twins are easy but the destroyer just like his name destroys you with his lasers I always end up killing him the last at least without an arena

Destroyer is pretty hard when new to hardmode, but who in their right mind would ever put eye of cuthulu and wall of flesh before lunatic cultist?

14 Eater of Worlds

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

I mean you think that is hard no

Easy to kill in my world

He was easy. - LordDovahkiin

15 Queen Bee

Maybe to you but not to me

She was easy. - LordDovahkiin

Easy man

16 Green Slime

Dude even with full slime armor and a slime staff I still can't beat this boss! Please help!

Can never ever kill it have best armour and weapons in game.

So hard had terra blade still could not beat it - JayJayPlayzzz

Too O.P please nerf

17 Skeletron

It was hard for me, I was in expert mode and had full Molten Armor and a Nights Edge.

Hardest in expert mode

He is easy I kick his butt with a nights edge and wood armor. he is a good thing to get the dryad

Is not very hard. - LordDovahkiin

18 Dungeon Guardian

Dungeon Guardian isn't even a mini boss, much less a boss. He is actually just a really powerful enemy. - LordDovahkiin

He does 1000 damage a hit and has a good amount of health

Not really a boss, but he drops something difficult to get, I killed this guy by using frost armor and vamp knives, the guardians killed me like 30 or more times beforr I got the bone key

Please tell meh how to beat this ABSOLUTE MONSTER, WHEN I TRIED TO GO DOWN THE DUNGEON THIS OP OF A CREATURE JUST COMES FLYING AT ME! AND NOT JUST ONE FRIKEN THREE! THREE?! CAN YOU believe THAT?! THREE! anyway, I just think I’m bad at the game. please help. too strong. only limit to one per world. I suck. ANYWAY. I like cheese. THIS HELL OF A WEIRD SKULL DUDE JUST SUPER, SUPER ANOYING. by the way when I was talking to that old guy I did the curse, and it said skeletron spawned and I was like; “what the hell” and I went into the dungeon, AND DIED IMMEDIATELY! I thought it was skeletron, but later realised it was only the dungeon guardian. And I was like; “holy crap, this dudes way too OP he needs to get nerfed.” please TELL ME HOW TO DEFEAT!

20 Dungeon Guardians

The 'Dungeon Guardian' is already on this list. Why is it on here again, and right below the first one

The dungeon guardians are hardest because of they hit you it causes 1,000 damage.


21 Slime

Is this really a boss in terraria or is it that its in a mod

This has to be 100x harder than the moon lord OR duke fishron

Slime is 174872401274291471207402170x harder than duke fishron.

I honestly don’t know how to defeat him, anyone have any tips?
