Terraria Progression Guide: The Order to Tackle Bosses and Biomes

Terraria has over 40 bosses, dozens of biomes, and 1600+ items across a progression that absolutely isn't intuitive. The game gives you a big sandbox and expects you to figure out the order. Players who don't know what to do next often waste hours trying to fight bosses they're underleveled for, or progress haphazardly and miss key content.

Here's the proper progression order, boss-by-boss, biome-by-biome, through the full game as of 2026 (including the final 1.4.5 content update).

What should you do first in Terraria?

Your first priority in Terraria is crafting basic weapons and armor, mining a gold or platinum pickaxe, and building NPC housing. Then tackle King Slime, Eye of Cthulhu, and Eater of Worlds or Brain of Cthulhu in that order, upgrading gear between each fight.

Starting loadout needed:

• Wooden sword/bow → copper/iron armor
• Mining gold/platinum pickaxe
• Demolitionist/Merchant/Nurse housing

Boss 1: King Slime (optional)

• How to summon: Slime Crown (crafted) or natural spawn
• Gear needed: Iron equipment minimum
• Drops: Ninja set, Slime gun, Royal Gel

Boss 2: Eye of Cthulhu

• How to summon: Suspicious Looking Eye (crafted) or natural at high HP
• Gear needed: Iron-tier gear, regen potions
• Drops: Demonite ore materials, Shield of Cthulhu (Expert)

Boss 3: Eater of Worlds / Brain of Cthulhu

• Corruption worlds: Eater of Worlds (breaking Shadow Orbs)
• Crimson worlds: Brain of Cthulhu (breaking Crimson Hearts)
• Gear needed: Iron/Lead full set
• Drops: Demonite/Crimtane materials, unique accessories

What do you do after Eye of Cthulhu in Terraria?

After defeating the Eye of Cthulhu and Eater of Worlds or Brain of Cthulhu, craft Demonite or Crimtane armor. Then head underground to find the Jungle Hive and fight Queen Bee, followed by Skeletron at the Dungeon entrance. Deerclops is an optional seasonal boss worth grabbing for unique drops.

Gear upgrade: Demonite/Crimtane armor, Shadow Scale/Tissue Sample gear

Boss 4: Queen Bee

• How to summon: Larva in Jungle Hive (break the honey larvae)
• Gear needed: Gold/Platinum gear minimum
• Drops: Bee armor, Bee-themed weapons, honey combs

How do you start Hardmode in Terraria?

To start Hardmode, you need to defeat the Wall of Flesh in the Underworld by throwing a Guide Voodoo Doll into lava. Equip Molten armor and bring a Minishark or Phoenix Blaster. Killing the Wall of Flesh permanently transforms your world, unlocking Hardmode ores, enemies, and biome spread.

Gear upgrade: Best pre-Hardmode armor (Necro, Jungle, Molten)

Boss 7: Wall of Flesh

• How to summon: Throw Guide Voodoo Doll in lava in Underworld
• Gear needed: Molten armor, Minishark or Phoenix Blaster
• Drops: Pwnhammer (unlocks Hardmode), Warrior/Ranger/Sorcerer Emblem, Breaker Blade

This fight starts Hardmode. The world changes dramatically after killing Wall of Flesh.

What should you do first in Terraria Hardmode?

Immediately after starting Hardmode, mine Cobalt or Palladium ore using your Pwnhammer-upgraded pickaxe, craft that armor set, and dig containment trenches around your base to stop Corruption or Crimson spread. Then fight the three Mechanical bosses (Destroyer, Twins, Skeletron Prime) in any order to unlock Hallowed Bars.

Immediate priorities after Hardmode:

1. Mine Cobalt/Palladium with Pwnhammer-upgraded pickaxe
2. Upgrade to Cobalt/Palladium armor
3. Contain Corruption/Crimson spread with mining trench around your base

Boss 8: Mechanical bosses (any order)

• Destroyer: Mechanical Worm summon
• Twins: Mechanical Eye summon
• Skeletron Prime: Mechanical Skull summon
• Gear needed: Mythril/Orichalcum armor for any of them
• Drops: Hallowed Bars for Hallowed armor

Boss 9: Plantera

• How to summon: Break Plantera Bulb in the underground Jungle (Hardmode)
• Gear needed: Hallowed or better armor, Megashark/Dart Pistol
• Drops: Venus Magnum, Seedler, Leaf Blower, Nettle Burst

Boss 10: Golem

• How to summon: Lihzahrd Power Cell on Lihzahrd Altar in Temple
• Gear needed: Chlorophyte or Turtle/Shroomite armor
• Drops: Sun Stone, Picksaw, Stynger

What bosses come after the Mechanical bosses in Terraria?

After the Mechanical bosses and Plantera, Duke Fishron and Empress of Light are optional but highly rewarding fights that drop some of the best weapons in the game. Duke Fishron can be summoned by fishing with a Truffle Worm, while Empress of Light appears after killing a Prismatic Lacewing in the Hallow.

Gear upgrade: Turtle/Chlorophyte → Shroomite (Ranger) / Spectre (Mage) / Beetle (Melee)

Boss 11: Duke Fishron (optional but great)

• How to summon: Fish with Truffle Worm in ocean
• Gear needed: Post-Plantera gear
• Drops: Razorblade Typhoon, Tempest Staff, Flairon, Tsunami, Bubble Gun

Boss 12: Empress of Light (optional but great)

• How to summon: Kill Prismatic Lacewing in Hallow during daytime
• Gear needed: Post-Plantera gear
• Drops: Sword of Light, Starlight, Terraprisma (day kill exclusive, extremely hard)

How do you reach Moon Lord in Terraria?

To reach Moon Lord, defeat the Lunatic Cultist at the Dungeon after Golem, then destroy all four Celestial Pillars (Solar, Vortex, Nebula, Stardust) that spawn across the map. Moon Lord appears automatically after the last pillar falls. Equip pillar-fragment armor matching your class before the fight.

Boss 13: Lunatic Cultist

• How to summon: Kill all Dungeon cultists after Golem
• Gear needed: Shroomite/Beetle/Spectre armor
• Drops: Summons Celestial Pillars event

Celestial Pillars

Four pillars summon: Solar (melee), Vortex (ranged), Nebula (magic), Stardust (summoner). Kill all four to summon final boss.

Pillar	Class	Fragment Armor
Solar	Melee	Solar Flare
Vortex	Ranged	Vortex
Nebula	Magic	Nebula
Stardust	Summoner	Stardust

Each pillar drops fragments for their corresponding armor set. Craft whichever matches your playstyle.

Boss 14: Moon Lord (Final Boss)

• How to summon: Automatic after killing all four pillars, or Celestial Sigil
• Gear needed: Solar/Vortex/Nebula/Stardust armor
• Drops: Meowmere, Star Wrath, Last Prism, S.D.M.G, Terrarian

This is the end of main progression. Congratulations, you've beaten Terraria.

What is there to do after beating Moon Lord in Terraria?

After defeating Moon Lord, Terraria shifts to endgame crafting, exploration, and challenge runs. Use Luminite bars to craft the strongest accessories and tools in the game, collect best-in-slot Celestial weapons for each class, explore remaining biomes, and replay the game on Expert Mode or Master Mode for extra difficulty.

Terraria doesn't have traditional post-game bosses but it has:

Luminite bars: Craft end-game accessories and tools Celestial weapons: Best-in-slot weapons per class Pyramids/Underground biomes: Post-game exploration Expert Mode / Master Mode: Higher difficulty replays

What did Terraria 1.4.5 add?

The 1.4.5 update was Terraria's final content patch, adding new challenges, items, and quality-of-life improvements to the endgame. This content expands on post-Moon Lord progression and gives veteran players more reasons to revisit the game. Check the wiki for the latest details.

The final content update added several new challenges and items. Check wiki for current state of 1.4.5 content as it's been expanded.

Can you fight Terraria bosses out of order?

Yes, skilled players can fight several Terraria bosses out of intended order for faster progression. Duke Fishron is beatable with Mechanical boss gear, and Empress of Light can be fought at night with post-Plantera loadouts. Daytime Empress is the ultimate skill check: a one-shot KO bullet hell encounter.

You can sometimes fight bosses out of order if you're skilled:

Duke Fishron early: A skilled player can kill Duke with Mechanical boss gear. Drops carry through post-Plantera.

Empress of Light at night: Normal difficulty. Skill check but doable.

Empress of Light in daytime: One-shot KO mode. Essentially bullet hell. Most difficult fight in the game.

What is the best class in Terraria?

Mixed class is the best choice for a first Terraria playthrough because it lets you adapt to each boss's weaknesses. For dedicated builds, Melee dominates early game, Ranged is consistent throughout, Magic peaks with Spectre armor in late Hardmode, and Summoner scales into the strongest late-game damage with investment.

Class	Strengths	Key Weapon Progression
Melee	Strongest early, great mid-game options	Terra Blade → Solar Eruption → Meowmere
Ranged	Solid all-around consistency	Megashark → Shroomite arrows → S.D.M.G.
Magic	Glass cannon with excellent AoE	Spectre armor is meta-defining
Summoner	Passive damage plus whip weapons, scales hugely late-game	Requires investment but strongest endgame scaling
Mixed (recommended first playthrough)	Adapts to boss weaknesses	Carry gear for multiple classes

What we make at Choost

Granny's Rampage is a bullet heaven, not a sandbox, completely different design. But Terraria is a masterclass in long-term content delivery we respect enormously. For more Terraria content, the terraria tips post has general advice, and the games like Terraria post covers the genre.

What is the full Terraria boss order?

The complete Terraria boss order is: King Slime, Eye of Cthulhu, Eater/Brain, Queen Bee, Skeletron, and Wall of Flesh in pre-Hardmode. Then Mechanical bosses, Plantera, Golem, optional Duke Fishron and Empress of Light, Lunatic Cultist, Celestial Pillars, and finally Moon Lord to finish the game.

Pre-Hardmode order: King Slime → Eye of Cthulhu → Eater/Brain → Queen Bee → Skeletron → Wall of Flesh.

Hardmode order: Mechanical bosses → Plantera → Golem → Duke Fishron (optional) → Empress of Light (optional) → Lunatic Cultist → Celestial Pillars → Moon Lord.

Gear progression: Copper → Iron → Gold → Demonite/Crimtane → Molten → Cobalt/Palladium → Mythril/Orichalcum → Adamantite/Titanium → Hallowed → Chlorophyte/Turtle/Shroomite → Spectre/Beetle → Solar/Vortex/Nebula/Stardust.

Prepare arenas and potions for every boss. Don't rush the progression, each boss is balanced around having the gear one tier behind. Terraria rewards preparation and respects your time investment.
