# Terraria: Complete Progression Guide (1.4.5 "Bigger & Boulder")

From your first night to Moon Lord: early priorities, the boss order, class gear by stage, NPCs and housing, and the big quality-of-life changes in the 1.4.5 update.

*Researched September 2026 — current as of 1.4.5.8 (PC, August 23, 2026). Live games change; check the linked sources if something differs.*

## Quick Start

1. **Build a shelter before the first night.** A room of wood walls, a door, a light source (torch), a table and a chair makes it valid housing for the **Guide**, who tells you what you can craft.
2. **Mine down for ore early.** Copper/Tin, then Iron/Lead, Silver/Tungsten, Gold/Platinum. Upgrade pickaxe and armor as soon as you can.
3. **Collect Life Crystals.** Each gives +20 max HP, up to 400. They're red hearts found underground. This is your biggest survival upgrade early.
4. **Get mobility.** Hermes Boots (or other speed boots), a **Cloud in a Bottle** (double jump) and a **grappling hook** make everything easier.
5. **Open every chest.** Surface and underground chests hide key early accessories and weapons.
6. **Use the new crafting quality of life (1.4.5).** You can craft from nearby chests, search the recipe list, and stack items to 9999.
7. **Pick a class, loosely.** Melee, Ranged, Magic and Summoner all work. Mixing early is fine; commit later for armor set bonuses.
8. **Build an arena for every boss.** Long platforms, campfires, heart lanterns and a Honey pool make fights far easier.
9. **Don't enter Hardmode unprepared.** Beating the Wall of Flesh changes your world permanently.
10. **Hit the Shimmer (Aether) when you find it.** It transmutes items and has several progression uses.

## What's New in 1.4.5

Terraria 1.4.5 "Bigger & Boulder" launched on **January 27, 2026**; the current PC patch is **1.4.5.8** (August 23, 2026, a bug-fix follow-up to the 1.4.5.7 QoL/balance patch of August 19), with console and mobile following.

- **Skyblock seed:** Start on a tiny floating island with a Shimmer island in the distance. You build the world from nothing.
- **Combinable special seeds:** Mix several special world seeds together.
- **650+ new items**, including 9 new whips, many furniture sets, hairstyles and paintings.
- **Crossovers:** **Dead Cells** (weapons like The Flint and The Killing Deck, the Beheaded vanity set, hanging flasks) and **Palworld** (five pals and a vanity set).
- **Crafting QoL:** Craft from nearby chests, a crafting UI with a **search bar and filter tabs**, a dedicated **banner menu**, and stack limits raised to **9999**.
- **Weapon reworks:** Phaseblades and Phasesabers can be thrown and embed in the ground. **Flairon** switches between projectile and flail modes. Conveyor belts can move items upward.
- **Balance:** Pirate invasion enemies were significantly weakened. Town NPCs get stronger as you defeat bosses.
- **QoL:** Minions are automatically resummoned when you respawn, the Housing query gives visual feedback, and rope/grapple handling is improved.
- **World gen:** New dungeon entrance variants and better liquid handling.
- **Mods:** As of September 2026 the stable **tModLoader** release (v2026.07.3.0) is still built on 1.4.4, so mods run on 1.4.4 content. Check tModLoader's status before planning a modded run.

## Default Controls (PC)

| Action | Key |
|---|---|
| Move / Jump | A, D / Space |
| Use item | Left click |
| Inventory | Esc |
| Grapple | E |
| Quick Heal | H |
| Quick Mana | J |
| Quick Buff | B |
| Smart Cursor | Left Ctrl (toggle) |

You can rebind all of these in Settings.

## NPCs and Housing

Valid housing needs walls behind it, a door or platform entrance, a light source, a flat surface item (table) and a comfort item (chair), and enough space. Use the **Housing** menu to check.

| NPC | How they arrive | Why you want them |
|---|---|---|
| Guide | Start of game | Crafting recipes |
| Merchant | 50 silver in inventory | Basic supplies |
| Nurse | Have 100+ max HP and the Merchant | Healing for coin (essential for bosses) |
| Demolitionist | Have explosives | Bombs, dynamite |
| Dye Trader | Have a dye ingredient or strange plant | Dyes |
| Arms Dealer | Have a gun or bullets | Ammo, Minishark |
| Dryad | Defeat any boss | Purification Powder, Seeds |
| Goblin Tinkerer | Rescue after the Goblin Army | Reforging, Tinkerer's Workshop |
| Mechanic | Free from the Dungeon | Wiring |
| Wizard, Truffle, Steampunker, Cyborg | Hardmode | Key mid/late items |

**Happiness** matters: happy NPCs sell cheaper, and NPCs only sell **pylons** when they're happy enough. A pylon needs at least two NPCs nearby to work. Put two compatible NPCs in their preferred biome. **Pylons** let you teleport between biomes.

## Pre-Hardmode Boss Order

| Boss | Summon / trigger | Why fight it |
|---|---|---|
| **King Slime** | Slime Crown or random | Easy, drops Slime Mount (Royal Gel in Expert) |
| **Eye of Cthulhu** | Suspicious Looking Eye at night | Unlocks Demonite/Crimtane progress |
| **Eater of Worlds / Brain of Cthulhu** | Break Shadow Orbs / Crimson Hearts, or use Worm Food / Bloody Spine | Shadow Scales / Tissue Samples for armor |
| **Queen Bee** | Break the larva in a jungle hive | Bee weapons and armor, great for summoners |
| **Skeletron** | Talk to the Old Man at the Dungeon at night | Unlocks the Dungeon |
| **Deerclops** (optional) | Snow biome, Deer Thing | Good accessories and items |
| **Wall of Flesh** | Throw a Guide Voodoo Doll into Underworld lava | Unlocks Hardmode |

**Hellstone** (mined with a Nightmare/Deathbringer Pickaxe or better) makes **Molten armor** and Molten Pickaxe, which is a strong setup for the Wall of Flesh. Build a long bridge across the Underworld first.

## Hardmode Progression

When the Wall of Flesh dies:

- **The Hallow** spreads, and the Corruption/Crimson gets more aggressive. Start containing it early.
- You get a **Pwnhammer**. Smash **Demon/Crimson Altars** to spawn new ores: Cobalt/Palladium, then Mythril/Orichalcum, then Adamantite/Titanium.
- **Queen Slime** (Gelatin Crystal in the Hallow) is an early Hardmode option.
- **Mechanical bosses:** The Twins, The Destroyer and Skeletron Prime. They drop **Hallowed Bars** for Hallowed armor and more.
- After all three mechs, **Chlorophyte** appears in the underground jungle and **Plantera** becomes reachable.
- **Plantera** (break a pink bulb in the underground jungle) opens the Jungle Temple and post-Plantera Dungeon.
- **Golem** (Jungle Temple, after Plantera) gives Beetle Tech and unlocks the Lunatic Cultist.
- **Duke Fishron** (fishing with Truffle Worm in the ocean) and **Empress of Light** (kill a Prismatic Lacewing in the Hallow at night) are optional but give great gear.
- **Lunatic Cultist** (Dungeon entrance after Golem) starts the **Lunar Events**: destroy the four Celestial Pillars (Solar, Vortex, Nebula, Stardust).
- **Moon Lord** summons after the pillars fall. He drops class-best gear and Luminite.

## Class Gear by Stage (Sample Paths)

| Stage | Melee | Ranged | Magic | Summoner |
|---|---|---|---|---|
| Early pre-HM | Gold/Platinum broadsword, Enchanted Sword | Bows, Boomstick, Minishark | Wand of Sparking, Water Bolt | Slime Staff, Finch Staff |
| Late pre-HM | Night's Edge, Molten armor | Molten Fury, Star Cannon, Phoenix Blaster | Space Gun (with Meteor armor), Demon Scythe | Hornet Staff, Imp Staff, Bee armor |
| Early HM | Cobalt/Mythril/Adamantite weapons | Clockwork Assault Rifle, Daedalus Stormbow | Crystal Storm, Cursed Flames / Golden Shower | Spider Staff, Spider armor, whips |
| Post-mech | True Night's Edge, Hallowed armor | Megashark, Chlorophyte Bullets | Rainbow Rod, Magnet Sphere | Optic Staff |
| Post-Plantera | Terra Blade | Tactical Shotgun, Chlorophyte Shotbow | Razorblade Typhoon | Raven Staff, Xeno Staff |
| Endgame | Zenith / Meowmere, Solar Flare armor | S.D.M.G., Vortex armor | Last Prism, Nebula armor | Stardust Dragon / Terraprisma, Stardust armor |

1.4.5 added nine new whips, so summoners have more options at every stage. Check the wiki for exact item stats.

## Key Accessories to Chase

- **Movement:** Hermes Boots, Cloud in a Bottle, Blizzard/Sandstorm in a Bottle, Frog Leg, Lightning Boots, Terraspark Boots, Wings (Hardmode).
- **Defense:** Cobalt Shield, Obsidian Shield, Ankh Shield, Worm Scarf / Brain of Confusion (Expert).
- **Utility:** Cell Phone / Shellphone line, Lucky Horseshoe, Magic Mirror.
- **Class emblems:** Warrior, Ranger, Sorcerer and Summoner Emblems, later Avenger Emblem and Destroyer Emblem.

**Reforge** accessories to Warding (defense) or Menacing/Lucky (damage/crit) at the Goblin Tinkerer.

## Resources and Farming

- **Life Crystals** (+20 HP each, up to 400), then **Life Fruit** in Hardmode (+5 each, up to 500).
- **Mana Crystals** (fallen stars at night) raise max mana.
- **Potions:** Ironskin, Regeneration, Swiftness, and the Endurance/Lifeforce/Wrath/Rage combo for bosses.
- **Fishing** gives crates (with ore and accessories), potion ingredients and quest rewards from the Angler.
- **Banners** from killing enough of an enemy give damage bonuses near the banner. In 1.4.5, they're stored in a dedicated banner menu.

## Common Mistakes to Avoid

- **Beating the Wall of Flesh before you're ready.** Hardmode spreads Hallow and Corruption/Crimson aggressively.
- **Not building an arena.** Boss fights without platforms, campfires and heart lanterns are much harder.
- **Hoarding items in random chests.** Use the 1.4.5 crafting search and nearby-chest crafting to your advantage.
- **Ignoring NPC happiness.** It raises prices and can stop NPCs selling pylons.
- **Skipping reforges and accessories.** Upgrading accessories is as important as your weapon.
- **Letting evil biomes and the Hallow spread unchecked in Hardmode.** Dig containment trenches around your base and key areas, or clean up later with a Clentaminator.

## Advanced Tips

- **Hellevator:** dig a straight shaft to the Underworld early. It speeds up everything.
- **Fishing crates** can fast-track pre-Hardmode ores and Hardmode ores.
- **Clentaminator** (Steampunker) purifies or converts biomes.
- **Use Shimmer** to transmute certain items and access unique uses of the Aether biome.
- **Skyblock seed** in 1.4.5 is a great challenge once you know progression well.
- **Combine seeds** in 1.4.5 for remixed worlds.
- **Buff stacking:** food (Well Fed), flasks for melee, and class potions add up.
