Use Special Seeds on Your Terraria Server

A seed decides how Terraria builds a new world. Besides a plain number or word, the game has named special seeds such as Not the Bees and secret seeds you unlock by typing their text. This guide shows how to get a seeded world onto your server, which means making it on your PC in Terraria and uploading it with World Import, and lists the special seed texts.

Checked against the Terraria wiki's world seed pages and TShock 6.2.1 for Terraria 1.4.5.8, October 2026.

Make the world on your PC

The Seed (optional) box in the New world window of the panel's Worlds tab doesn't currently apply seeds on TShock, so don't rely on it for a special seed. Make the world in Terraria on your PC with the seed you want, then upload it.

1. Start Terraria on your PC at the same version as your server. TShock 6.2.1 is built for Terraria 1.4.5.8, so that is the version to use.
2. Create a new world. In the world creation screen, type the seed text into the World Seed box, or press the seed icon beside it to open the Seed Menu and switch seeds on.
3. Give the world a name of up to 20 letters, numbers, dashes and underscores. The file name becomes your server's World name.
4. Finish creating the world, quit Terraria and upload the .wld file with the World Import tab. Upload a Terraria world to your server has every step, including where the file is on your PC.
5. Start the server. The world marked Loads on start in the Worlds tab is the one it opens.

Our code installs the uploaded .wld as it is: it renames the file from the upload folder into the world folder and sets World name to match, and it doesn't rebuild the world (lib/terraria/world-import.ts).

Check your server software

The Server software card on the Startup tab shows whether you run TShock or tModLoader. The seed combinations and the Skyblock seed arrived in Terraria 1.4.5.0. TShock 6.2.1 is built for Terraria 1.4.5.8, but tModLoader's current stable builds are still based on Terraria 1.4.4, so those two are only available on TShock.

Special seeds

The official Terraria wiki lists these special seed texts and what each seed does. Re-Logic's own changelogs also name the Skyblock, Remix, Zenith, No Traps and The Constant seeds.

According to the wiki's Secret world seeds page, secret seeds include beam me up and waterpark. Seed texts are version-sensitive, so check the wiki before you rely on one.

Combine several seeds

The official Terraria wiki says typing a code into the seed box turns on one special seed only, and typing a second code switches the first off. Combining seeds is done in the Seed Menu beside the World Seed box, so make a combined world on your PC with the steps above and switch on every seed you want.

If the seed didn't take

• The world looks ordinary. Check the Worlds tab: the world marked Loads on start is the one the server opens. If it isn't the uploaded one, press Switch to on its row and restart.
• Your old world seems gone. A world with the same name already on the server is kept and renamed with pre-import and the date in its file name, never overwritten. Look for it in File Manager.
• Skyblock does nothing on tModLoader. The seed arrived in Terraria 1.4.5.0 and tModLoader's current builds are based on 1.4.4, so run TShock for it.
• Friends can't join. The server and their game must be the same version. How to join your Terraria server covers it.
