Terraria 1.4.5 World Selection Guide: Skyblock, Secret Seeds & Best Combos (2026)

Terraria’s Bigger & Boulder 1.4.5 update completely reshapes how new worlds begin — and picking the right world seed is now one of the most exciting decisions you’ll make before even stepping into your next adventure. With the addition of an official World Seed Menu, a brand‑new Skyblock world, dozens of secret seeds, and the ability to combine multiple seeds for unique effects, world creation has become just as fun and strategic as combat and building.

Whether you want a classic experience, a resource‑scarce survival challenge, or something delightfully strange, this guide will walk you through all the options and help you choose the best seed for your playstyle.

🌍 What’s New in 1.4.5 World Generation

Terraria’s world generation system got one of its biggest upgrades in years with 1.4.5:

✔ Skyblock Seed

A brand‑new secret seed added in this update. You start on a small floating island with no ground and extremely limited resources — a unique challenge that forces you to rethink survival and progression from day one.

✔ World Seed Menu

Instead of manually entering codes, Terraria now shows you a seed selection menu during world creation. You can browse and enable special seeds and even stack multiple seeds together for new experiences.

✔ Secret Seeds & Effects

1.4.5 includes a variety of secret seeds — both the classic ones and new ones introduced with this update. You can enter these manually or use them in combinations to unlock unusual effects like constant rain, flipped terrain, or seasonal worlds.

🧠 How World Seeds Work in Terraria

Before diving into specific seeds, here’s how they function:

Every world has a seed string that determines its layout and features.
Special world seeds are seeds with specific effects (e.g., Skyblock or For the Worthy) and can now be selected via the new menu.
Secret seeds produce more unexpected or dramatic changes but usually need to be typed in manually.
You can combine multiple special seeds to create worlds with combined effects, often producing entirely new gameplay experiences.
