Terraria boss fight


Terraria features a total of seven standard bosses and ten hardmode bosses to summon and defeat. Some of these fights are optional, so follow the instructions below to seek them out.

What order should I fight bosses in Terraria?

You can fight most Terraria bosses in any order, provided you know how to summon them. Of course, you first need to reach hardmode if you want to battle it out against its exclusive bosses. You can check out our recommended order in the list below.

Who is the strongest boss in Terraria?

Terraria’s strongest bosses are undoubtedly the almighty Moon Lord and Duke Fishron. While the former is technically Terraria’s final hardmode boss, the latter puts up just as tough a fight, even with his comparatively small health pool.

The Wall of Flesh boss

all standard Terraria bosses explained

These are the seven bosses you can duke it out with in Terraria’s standard mode. We’ve listed them in order of when you should attempt to fight them.

King Slime

You can summon this big ol’ slime by using a Slime Crown or defeating 150 mini slimes during a slime storm, which is a random in-game event where slimes fall from the heavens. King Slime is a bit of a pushover, making him an easy first boss.

Queen Bee

Queen Bee is one of the simplest Terraria bosses of them all, and you can summon her by destroying her larva within the underground jungle. You can also use an Abeemination anywhere in the jungle biome in order to spawn her straight away.

Eye of Cthulhu

The Eye of Cthulhu is a gross, fleshy eyeball that has a one in three chance of spawning in the evening once you have at least 200 HP, ten defence, and three or more NPCs living in your town. You can also opt to summon it yourself by using a Suspicious Looking Eye at night.

Eater of Worlds

The Eater of Worlds is almost as disgusting as the Eye of Cthulhu, being a ruddy giant worm and all. Thankfully, it’s only available in worlds filled with corruption. You can wake it up by breaking three Shadow Orbs found deep within corruption chasms using a pickaxe with at least 65% power. Naturally, explosives will also do the trick.

Brain of Cthulhu

Oh look, another revolting Terraria boss. This one’s a murderous brain with a gaping, toothy maw. Just… no. You can summon the Brain of Cthulhu by hammering away at three Crimson Hearts found within crimson chasms. Alternatively, you can use a Bloody Spine to instantly summon the beast.


Skeletron is a towering skeleton who possesses the strength to kill you in a single hit if you don’t defeat him before the night is through. You can summon him by chatting to the old man at the entrance to the dungeon during the evening. Steel yourself for a tricky fight with this one.

Wall of Flesh

You’ll face off against the Wall of Flesh just before entering hardmode. As its name suggests, it’s another disgustingly fleshy Terraria boss with a sizeable health pool and formidable strength. You can summon it – if you dare – by lobbing a Guide Voodoo Doll into a pool of lava.

All hardmode Terraria bosses explained

These are the ten bosses you can take on in Terraria’s standard mode. We’ve listed them in order of when you should attempt to fight them.

Queen Slime

Queen Slime is the first of Terraria’s ten hardmode bosses, not to mention one of its easiest. She’s pretty similar to King Slime during her first phase, and you can summon her by using Gelatin Crystals in the Underground Hallow. Note that Queen Slime is another optional boss, so if you’re struggling to take her down, you can safely move to the next.

The Destroyer

Despite its scary name, The Destroyer is a bit of a pushover. It’s a mechanical behemoth that looks intimidating but is pretty straightforward to take down. It’s similar to the Eater of Worlds in many ways, though The Destroyer boasts a giant health pool. You can summon it by using a Mechanical Worm in the evening.

The Twins

Remember the Eyes of Cthulhu? Well, they’re back and now boast fancy cybernetics. One likes to shoot you from afar, while the other favours a more up-close approach, slamming into you and spewing out fire when it feels like it. You can summon them by using a Mechanical Eye in the evening.

Skeletron Prime

Skeletron Prime is an enhanced – and far trickier – version of old Skeletron. He now has four deadly limbs, each wielding its own weapon, though you’ll still only have to finish off his head to take this giant down. You can summon Skeletron Prime by using a Mechanical Skull in the evening.


Plantera is a giant, man-eating plant that loves to fire deadly seed at you. You can only take on Plantera once you’ve defeated Skeletron Prime, The Twins, and The Destroyer. Once you’ve done so, you can summon the beast by destroying one of her bulbs in the Underground Jungle.


Golem is a giant stone creature that functions a little like Skeletron. Once you’ve dealt enough damage to Golem’s head, the thing will pop clean off and start flying around the place. You can summon him by using a Lihzahrd Power Cell in the Jungle Temple’s Lihzahrd Altar, which you can only gain access to after defeating Plantera.

Empress of Light

Empress of Light is one of hardmode’s toughest bosses, especially when fought during the day, which makes us thankful that she’s entirely optional. She flies around the arena, making her tricky to hit, and has one of the game’s most versatile movesets. You can summon her by killing a Prismatic Lacewing, which can sometimes be found in the Surface Hallow once you’ve defeated Plantera.

Lunatic Cultist

The Lunatic Cultist doesn’t look like much at first glance, but his fireballs and lighting attacks are a pain to deal with, as are the doppelgangers he so likes to spawn in. You can fight Lunatic Cultist once you’ve defeated the four buddies, found outside the Dungeon once Golem is down.

Duke Fishron

Just when you think Terraria bosses can’t get any weirder, the game goes and pulls out Duke Fishron. This strange mix of a dragon, pig, and a shark puts up one of the game’s most challenging fights, boasting many devastating attacks, including explosive bubbles a tornado of sea creatures. You can summon him by using a Truffle Worm as bait when fishing in the Ocean biome.

Moon Lord

Moon Lord is Terraria’s true final boss, so come prepared. You can destroy his hands and head by attacking their giant eyes, but once you do, his chest cavity pops open, revealing another stage. You can summon Moon Lord by using a Celestial Sigil or taking down four Celestial Pillars. Good luck!
