The Terraria 1.4.5 Bigger and Bolder update is here, allegedly as the final major Terraria update, and it has the energy of a game that found a box labeled “cool ideas we never shipped” and dumped the whole thing into production. Released on January 27, 2026, this Terraria update does not behave like a tidy end-of-life patch. It behaves like a victory lap where someone keeps adding laps.
If you are searching what is new in Terraria 1.4.5, prepare for a list that spirals from meaningful system changes to “you can now own an emotional support boulder.”

What Is in the Terraria 1.4.5 Bigger and Bolder Update?
Basically, it’s the everything update. The Terraria 1.4.5 update overhauls how players fight, build, and even generate worlds. It adds crossovers, weapons and skills, expanded furniture and decoration systems, strange new enemy types, and seed combinations that fundamentally change your world behaves. It’s not just a content bump, it’s Terraria pushing every lever at once.
This article has the highlights, but if you want the full, ultra-detailed list, check out ReLogic’s official post & the 1.4.5 changelog here.
Terraria 1.4.5 Release Time and Launch
It’s out! The Terraria 1.4.5 Bigger and Bolder update launched on January 27, 2026. There were a few hiccups with platforms and storefronts, but the update is now live everywhere, and, as is tradition, players are starting new worlds to play the game anew.
Terraria 1.4.5 Crossover Content
Two crossovers headline this Terraria 1.4.5 update: Dead Cells and Palworld, which is a sentence that reads like a mod list but is official.
From Dead Cells, the Beheaded outfit joins Terraria’s already chaotic closet. Palworld contributes Cattiva, Foxparks, and a summonable Digtoise that can mine through blocks for you. Yes, you can now bring a small creature whose job is doing your chores, a development that says troubling things about both game design and us.
Pal Metal armor also enters the gear pool, blending Palworld’s look into Terraria progression in a way that feels absurd and completely on brand for 2026 crossover logic.
New Weapons and Combat in the Terraria 1.4.5 Update
Combat gets a serious expansion in Terraria 1.4.5. New ranged weapons like the Barrel Launcher and Killing Deck join melee additions such as the Flint weapon. Summoners gain the Mushroom Staff, which calls in a “Mushroom Boi” minion, a name that sounds like a meme and is not.
Whips, specifically, are having a moment. The Terraria 1.4.5 update adds a Moon Lord whip, Stardust and meteor themed whips, and biome or boss inspired ones tied to Corruption, Crimson, Plantera, Slimes, and more. For whip builds, this is less a balance pass and more a lifestyle update.
New abilities like The Swarm grenade skill, The Ram Rune, and Wings of the Crow, plus additional sentries and boss themed gear, widen combat styles while continuing Terraria’s long tradition of letting you dress like something you just defeated.
Building and Furniture in Terraria 1.4.5
The Bigger and Bolder update quietly turns Terraria into an interior design sandbox with combat attached. New furniture sets span Gothic, Modern, Feywood, Aetherium, Moon, Snow, Pine, Cloud, Harpy, Metal, and Book themes, among others. Honey coated furniture, Fallen Star bricks and walls, Music Blocks, CRT televisions, film projectors, and arcade machines mean your base can now look like a wizard’s attic, a space cult shrine, or a haunted 90s living room.
Functional decor also grows. A Health Fountain grants a buff, flasks can display items, and new wall types add more visual variety. If you were already overengineering houses in Terraria, this update enables you further.
New Mounts, Pets, and Accessories
Terraria 1.4.5 adds mounts that feel pulled from five different games at once: Velociraptor, bat, rat, fairy, and roller skates. Pets include an Axe Fairy that helps harvest wood and a Pufferfish, because even your companions now come with utility or mild chaos.
Accessories lean into novelty with items like a Tamagotchi, Stress Ball, and Silly Balloon. Smaller additions such as an RC car, pan flute, new food, and extra sound effects give this Terraria update the tone of a toy box that has been aggressively overturned.
New Slimes and Enemies
Several new slime variants arrive in the Terraria 1.4.5 update, and they come equipped. These slimes carry items inside their bodies that affect how they behave. A Cloud Slime jumps higher with a Cloud Block. A Dart Trap Slime shoots darts. A Moonglow Slime emits light and plants herbs. Others haul dirt, granite, or glowing slush.
They appear more often in the Skyblock seed, turning that mode into a bouncing ecosystem of mobile hazards and loot delivery systems.
Seeds and World Changes in Terraria 1.4.5
A new Seeds menu lets players combine different world seeds, and the results get weird fast. Some combinations can turn the player into a vampire, replace ocean water with Shimmer, or make heavy rain cause floods. Terraria 1.4.5 leans harder than ever into the idea that the world itself can be the gimmick, not just the enemies or loot.
The Boulders in the Bigger and Bolder Update
Terraria’s long running love of boulder traps graduates into a full feature set in this update. The Terraria 1.4.5 update adds upward falling boulders, thunderstorm “Boulder Rain,” magma covered boulders, and yes, a Poo Boulder. A special Rainbow Boulder in certain secret seed combinations ricochets between ores and chests while passing through blocks and not harming the player.
There is also a Boulder pet. Terraria is aware of the bit and has chosen to commit.
Is Terraria 1.4.5 the Final Terraria Update?
Re-Logic has described 1.4.5 as the final major Terraria update, though the studio has said similar things before. Whether this is truly the end or just another “final” chapter, Bigger and Bolder plays like a game unloading years of ideas in one go.
So, Terraria 1.4.6, Terraria 1.4.6 release time, or what is in the new Terraria update, the answer is simple. A lot. Possibly too much. Exactly the right amount.
