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.

2 Moon Lord

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

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

Anyone hoo says fishron has the big gay

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

This boss is near impossible in expert mode it took me like 10 attempts with nurse and auto pause

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

The first phase is super easy then the second one just trashes me, the way I beat it was I ran down acart tunnel to avoid death...

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

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

Skeletron prime isn't very hard he may have many attacks but when I use the good n shower spell on him that ichor debuff almost drops his defense to 0 twins are hardest mechanical boss ;-)

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.

He shoots lazers out of his eyes called eye beams

7 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

Skelotron is one of the hardest bosses too

8 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!

He's ok but very challenging to me and I have 45 defense so he deserves 10th

Dude, I have 53 DEFENSE and he's still the hardest other than Fishron, Prime and Twins.

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

9 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

It is this boss

Screw orcram I tried fighting with 40 armour and using the true Excalibur and I still died

10 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

Easiest boss ever! I won with lights bane

I killed him w/ enchanted Sword

The Contenders

11 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

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?

12 King Slime

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

This is on the wrong list, people. - LordDovahkiin

13 Brain of Cthulhu
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

16 Skeletron

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

17 Dungeon Guardian

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

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

Well I just play terraria for 2 days and when I see a dungeon I go deep inside it and well you know what happen..i died the dungeon guardian is like the strongest enemy I ever met he did 1000 dmg to me

If this was an actual boss, it would be very difficult. 9999 HP and you do 1-2 damage per swing. It can also kill you in 1-2 hits.
