Frostbite Tundra - World 3 Guide - IdleOn

June 30, 2025

Frostbite Tundra is World 3 of IdleOn and becomes available after you have defeated Efaunt in World 2. World 3 is host to the Construction Table, the beloved 3D Printer and Refinery Salts that allow you to craft better equipment.

Our World 3 Guide will serve as a homepage hub for all activities available in Frostbite Tundra and also give you a decent guide of how to progress through it. Even though World 3 adds more features and content, you should still be working on your World 2 and World 1 mechanics also.

Once you defeat normal Efaunt and obtain the Glacier Quartz from him, you'll be able to access the Frostbite Tundra.

The following areas are available in World 3:

World 3 Progression Guide

Refinery

World 3 introduces the Construction Table, which allows you to build several more mini-mechanics within the World.

You should work on your Construction Table and Refinery the most in World 3. They both work in tandem, with the salts you produce from the Refinery going towards upgrading any new towers from the Construction Table.

Aim to unlock all the important World 3 Towers as soon as possible; the 3D Printer will allow you to print millions of resources, you can upgrade your max talent level with the Talent Library, there's the Automation Arm that can help out with a host of quality of life improvements and the Atom Collider has plenty of upgrades worth investing in.

You'll also want to work on both Worship and Trapping skills, as the items they give are also used in Construction.

The Equinox Dream isn't worth pushing for this early on in the game, so we recommend coming back to it once you've unlocked World 5. Many of the Equinox Tasks require more medium-game progression.

Armor Set Smithy

Equipment Sets are time-gated unless you've purchased 2K gems, but are well worth investing in once available. Speak to the Armor-Smithy to see which ones you have unlocked.

Prayers are also an end-game type of mechanic, since many of the curses require a super powerful character to be able to ignore them.

Here are all the items you can find in the World 3 Town Shop.
