Terraria 1.4.5 World Seeds: what the new Seed Menu changes & best seeds to try

TL;DR

Terraria dedicated servers 1.4.5 adds a proper World Seed Menu, so you can pick special seeds without memorizing code words or copy-pasting from a wiki. You open it from world creation by clicking the small seed icon next to the World Seed field, choose a seed (or multiple), then hit Apply. The big upgrade is that special and secret seeds can be combined, and some combos have their own extra twists. If you only try a few, start with Skyblock for a fresh solo challenge, royale with cheese for a friend group, and jingle all the way or hocus pocus for permanent seasonal vibes.

Quick Terraria 1.4.5 note

This article is about Terraria 1.4.5 (Bigger & Boulder). If you do not see the seed icon during world creation, you are likely on an older version, or your platform has not updated yet.

What counts as a world seed in Terraria (and why 1.4.5 feels different)

In Terraria, the normal world seed is the number or text you type when you generate a world. It mainly controls how that world is shaped, like where the Jungle ends up or how caves snake around.

Special and secret world seeds go further. They can change the rules of the world, the vibe, progression pressure, and sometimes how multiplayer starts. Before 1.4.5, a lot of players simply never touched these because the process was a little too hidden: you had to know the exact code phrase, type it correctly, and then remember what it did later.

Terraria 1.4.5 makes those worlds much easier to access and experiment with, which is why seeds suddenly matter to beginners again. You can now browse the main special seed types, select them like options, and mix them on purpose.

What the new World Seed Menu changes in 1.4.5

If you have ever tried a special seed before, the improvement is instantly obvious:

You no longer need to hunt down a phrase and manually type it. The World Seed Menu surfaces the main special seed world types directly in the Create World flow.

You can combine seeds. This is the real headline. The menu is not just a shortcut, it is a playground. You can pick multiple special seed effects for a single world, and Terraria 1.4.5 explicitly supports that. Some combinations can even unlock additional effects.

It reduces rookie mistakes. No more wondering whether an exclamation mark mattered, or whether your seed was ignored because of a typo. You choose it, apply it, and you are done.

Micro-scenario: You and two friends want a fresh world tonight, but nobody wants to spend 20 minutes debating difficulty rules. With the menu, you can pick a seed that sets the tone (challenge, seasonal, weird worldgen), generate, and start playing in under a minute.

How to use the Seed Menu

When you create a new world, look for the World Seed field. In 1.4.5, there is a small seed icon next to it. Clicking that opens the World Seed Menu.

From there, you can:

• pick a special seed world type from the list

• select more than one seed to combine effects (if you want)

• hit Apply to push those choices back into world creation
  

You can still type a normal seed manually. Think of it this way: the seed text controls the layout, while the Seed Menu controls special rule-sets and world modifiers.

Quick creation flow you can alt-tab back to

• Create World

• Find World Seed

• Click the small seed icon

• Choose one seed, or choose a combo

• Hit Apply

• Generate the world
  

Picking seeds on purpose: a simple way to choose the right one

A lot of seed guides are basically a catalog. That is not helpful when you are new. Instead, decide what kind of session you want:

Do you want a learning-friendly world, or a world that forces you to improvise?

Do you want solo exploration, or a multiplayer world that naturally splits people up?

Do you want a normal vibe, or a themed vibe that stays themed without messing with your system clock?

Once you answer those, the Seed Menu becomes a menu in the literal sense: you are ordering the kind of playthrough you want.

The best 1.4.5 seeds to try first

These are the most immediately useful or fun picks tied directly to what 1.4.5 introduces: the Seed Menu, new secret seeds, and official support for combinations.

Skyblock world seed (the cleanest fresh start)

If you want something that feels new even if you have played Terraria for years, Skyblock is the one. The official idea is simple: there is no real ground, and you begin on a tiny island in the sky.

Why it works: it forces you to treat every block like it matters. Building is not just decorating, it is survival. Early mistakes are memorable, but not confusing.

A few beginner-friendly tips that do not spoil anything:

Start by making your island safe to move around on. Add platforms or railings so one bad jump does not end the run. Expand slowly, and build a small, organized base before you get ambitious.

Micro-scenario: If you normally start worlds, build a box, then wander until you find something interesting, Skyblock flips that. Your base is the interesting part from minute one.

Royale with cheese (built for friend groups)

This is a new secret seed designed to change how multiplayer starts. Instead of everyone spawning together, each team gets a different starting position.

It is great for:

Co-op groups that want some friendly separation, PvP teams, or any group that likes the idea of separate bases and trading rather than one shared pile of chests.

Practical advice: decide teams before the first night. If everyone joins and switches teams repeatedly, it is easy to get confused about where home is. Make beds and basic shelter early so your start location stays meaningful.

Hocus pocus (permanent Halloween vibes)

Same idea as the Christmas seed, but for Halloween. If you prefer spooky over cozy, this is the easy win.

This one is especially fun for a short group series, because the theme does a lot of work on its own. You can build around it, decorate around it, and keep the whole run feeling cohesive.

Remix + Not the Bees! your first combo experiment

Terraria 1.4.5 explicitly calls out combining seeds and even teases fun mashups. Remix plus Not the Bees! is a great first experiment because it teaches you what combining is really for: layering a big world-rule shift with a strong biome identity.

You do not need to fully understand either seed to enjoy this. Generate it, explore for ten minutes, and you will immediately feel whether the combo is a keeper.

A good mindset for combos: start with two. If you stack too many special seeds at once, it can be hard to tell which rule is causing what, and beginners tend to assume they did something wrong.

How to share seeds with friends

If you are playing with a group, the cleanest approach is to agree on two things before you generate:

1. the seed choice or seed combo

2. the difficulty mode
   

Then let the world teach everyone what that choice means. The whole point of the Seed Menu is that you do not need to memorize a wiki entry to get value out of it.

If you are trying to avoid spoilers, skip browsing community lists and instead pick your seed inside the menu based on vibes. You can always run the world for 15 minutes, keep it if it is fun, or reroll if it is not.

Common mistakes and quick fixes

• If you cannot find the seed icon, you are probably not on 1.4.5 yet. Update the game, then check world creation again.

• If your world feels normal, double-check that you clicked Apply in the Seed Menu. Closing the menu without applying can leave you with a standard world.

• If your multiplayer group still spawns together on royale with cheese, make sure players actually pick teams after joining. The seed is team-based, so the team choice matters.

• If your combo feels unfair or chaotic, reduce it to a single seed and add a second one later. Many special seeds are designed to be disruptive on their own.

• If you copied a seed phrase from somewhere and it did not work, try using the Seed Menu instead. It avoids typos and removes ambiguity.
