Terraria 1.4.5 Bigger & Boulder: Everything Added, Changed, and Improved

If you thought Terraria was done getting updates, you were wrong. Re-Logic just dropped 1.4.5 “Bigger & Boulder” on January 27, 2026, and it’s massive. We’re talking 650+ new items, complete UI overhauls, game-changing quality-of-life fixes, and enough content to make you reinstall the game even if you swore you were done.

This update started as a small list of loose ends and turned into what feels like a whole new game. Let’s break down everything that changed, what got added, and why the community is going crazy over it.

The Crafting System Got a Complete Overhaul

The biggest change? Crafting doesn’t suck anymore.

Before 1.4.5, scrolling through hundreds of recipes was a nightmare. Now, the crafting menu works like Journey Mode’s research system, organized by tabs (Weapons, Furniture, etc.) with a search bar so you can actually find what you need.

But here’s the game-changer: you can now craft directly from nearby chests. No more filling your inventory with materials, opening twenty chests, or forgetting where you put that one iron bar. Toggle “craft from nearby chests” on, and the game automatically pulls materials from storage when you craft. It’s a massive time-saver.

Also, all identical items now stack up to 9,999, regardless of their prefixes. Quick-stack options got smarter too, combining similar items (like different ores) automatically. If you’ve ever spent half an hour organizing potions and materials, you know how big this is.

World Seeds Just Got Way More Interesting

Terraria always had secret world seeds, but you had to know the codes and type them manually. 1.4.5 fixes that with a new World Seed Menu that shows you all the special seeds right when you’re creating a world.

You can pick presets like Skyblock, Remix, Not the Bees, and more. But here’s where it gets fun: you can combine seeds. Want a Remix + Not the Bees world? Go for it. Specific combinations even unlock hidden effects.

The new Skyblock seed is amazing. You spawn on a tiny floating island with almost no land below, turning survival into a resource management puzzle. There’s also “Royale With Cheese,” which creates team-based spawn points across the map. Each team gets its own starting area, and when we tested it, it completely changed how multiplayer felt.

Other seeds include “Jingle All The Way” (permanent Christmas), “Hocus Pocus” (permanent Halloween), and one that makes it rain constantly. There’s even a secret seed that massively expands the Dungeon, but Re-Logic didn’t announce the code; you have to find it yourself.

If you thought world generation was getting stale, this changes everything.

Over 650 New Items

Re-Logic really delivered on that 650+ new items claim, and it’s legit. Item totals now over 6,000.

Here is a list of them (almost all of them):

  • Axearang – Throwable axe that chops trees

  • Hardmode ore destroyer bomb

Dead Cells Crossover

The Dead Cells crossover finally arrived. Motion Twin released their side of the crossover a while back, and now Terraria has Dead Cells weapons (Flintlock, Barrel Launcher, Killing Deck), decorative flasks, and the Beheaded vanity set. These aren’t just reskins either; the weapons feel authentic to both games.

Palworld Crossover

The Palworld crossover is even cooler. Instead of just vanity items, you get functional companions.

Digtoise mines blocks for you autonomously.

Cattiva chops wood for you.

You can carry Foxparks as a flamethrower. They’re not pets; they’re actual helpers that make grinding resources way faster.

New Weapons and Tools

Summoners got at least nine new whip variants, plus new prefixes. There are new flails, a Slime Spear, and ranged options like the Acorn Slingshot (which plants trees when you shoot it). The “Mitey-Titey” lets you place stalactites and stalagmites manually. Roller Skates let you grind on rails.

Building and Furniture

Dozens of new furniture sets (Gothic, Aetherium, Corruption, Crimson), new blocks (Fallen Star brick, cloud platforms), music blocks that play notes, mud balls for placing mud, and even a CRT TV and film projector as decorations.

Consumables

Freeze Bombs, Hyper Bombs, and the Jungle Juice potion, which is crafted using Life Fruit, expand your options in the endgame. There is also a stress ball accessory that automatically attacks while you stand still, a magic string that increases yo-yo speed, and vanity items that change your hurt sounds to animals like chickens, goats, or turkeys.

Boulder Mechanics

True to its name, this update goes heavy on boulders.

You’ve got upward-falling boulders (blocks that shoot up), rainbow boulders that bounce between walls, Poo Boulders (yes, really), magma boulders, and even a boulder rain weather event. Boulders now trigger traps and interact with conveyors. Falling sand or boulders on conveyor belts are picked up as items rather than settling.

Basically, the landscape fights back now. Even standing at the bottom of the world has consequences.

Big Changes That Actually Matter

Spectator Mode

When you die in multiplayer, you used to just stare at a respawn timer. Now you can spectate other players. Watch your friends fight the boss, see if they’re stealing your coins, or catch their strategy. It turns deaths into a social experience instead of dead time.

NPC Housing

NPCs don’t need a proper house to show up anymore. They’ll spawn unassigned and despawn at night if unhoused, so no rush to slap together that starter housing grind.

The housing check tool now uses icons to flag missing stuff visually, instead of plain text lists.

Banner Collection Menu

Mob banners are now stored in a shared menu instead of your inventory. You can still retrieve and place them manually, but they don’t clutter your storage anymore.

Character Creation

You can now pick your hurt-sound type and pitch. Character and world selection lists sort by most recent and mark new or visited worlds. Gamepad and mobile controls got radial menus, multi-touch support, and button hints.

Multiplayer Improvements

Faster auto-stacking on chests, indicator icons if a chest is unavailable, and you automatically join your last-used team on re-entry.

Visual and Audio Polish

The update adds atmospheric touches everywhere. Thunderstorms now include damaging lightning strikes that can hit enemies and trees. NPCs have speaking portraits in dialogue. New backgrounds for sunrise/sunset and aurora borealis in snow biomes. Ambient insects and rubble animations enrich the world.

Every vanilla boss got a brand-new theme. King Slime, Eater of Worlds, Queen Bee, Skeletron, Twins, Destroyer, Lunatic Cultist, and more all have fresh music. You can even choose between four title-screen music sets (old, new, console, or random).

Thunder, lava, item, and UI sound effects were added or tweaked. Lava splashes when fishing, drill sounds, and auto-attack cues for kites. The audio-visual package makes the game feel richer than ever.

A Love Letter to Fans

There’s also a Make-A-Wish component. In June 2024, Re-Logic revealed they were adding a vanity set for Frank, a Terraria fan battling leukemia. The Heroicis set (named after his character) finally launched with 1.4.5, complete with a film noir shader.

Frank wrote a message in the launch post: “Yes, I had leukemia, that doesn’t define me. Yes, I have permanent neurological issues, but that doesn’t define me… Whatever you’re going through doesn’t have to define you. You’re stronger than you’ll ever know.”

The set has a special obtainment method players need to discover, adding another layer of community engagement.

What This Means for Players

If you stopped playing Terraria because you “finished” it, now’s the time to come back. The crafting overhaul alone makes the game feel smoother. The world seeds add replay value. The new items give you more “toys” to play with.

For new players, this is the best version of Terraria ever. The UI improvements lower the barrier to entry, and the quality-of-life changes eliminate old frustrations.

For veterans, the crossovers, new mechanics, and atmospheric polish breathe fresh life into a game you already know inside out.

Summary

Terraria 1.4.5 “Bigger & Boulder” is a colossal expansion that adds new gameplay systems (world seeds, boulders, mounts), dozens of quality-of-life improvements (crafting UI, stacking, spectator mode), hundreds of items (furniture, weapons, pets), and audiovisual polish.

The update launched on January 27, 2026, across PC, consoles, and mobile. It includes:

  • Complete crafting UI overhaul with chest-crafting support
  • 9,999 item stacking for all identical items
  • World Seed Menu with combinable presets
  • 650+ new items (Dead Cells and Palworld crossovers, new weapons, furniture, consumables)
  • Boulder mechanics and boulder rain weather
  • Spectator mode for multiplayer
  • Banner collection menu and improved NPC housing
  • New boss music for every vanilla boss
  • Thunderstorms with damaging lightning
  • Make-A-Wish Heroicis vanity set

The launch generated ~164,000 concurrent players on Steam, nearly 2,900 reviews in the first day (97% positive), and overwhelming praise from the community. Players called it “a love letter to fans” and “peak Terraria.”

Re-Logic started this update as “a small list of loose ends” and turned it into what feels like a whole new game. If you thought Terraria was done, Bigger & Boulder proves otherwise. For fans and new players, this update delivers an immense amount of content that makes the game feel richer, smoother, and more engaging than ever.

Happy digging!
