Revision 3

Eternal Alloy

Eternal Alloy is the endgame metallic crafting output in Starsand Island. It is smelted at the Furnace III using Aurorite Ore as the primary ingredient. Eternal Alloy gates the two most expensive mechanical tools in the game: the Electric Drill and the Chainsaw. Each tool consumes 6 Eternal Alloy, making this the second-most-demanded endgame material after High Performance Wire Sets.

Production

Furnace III is unlocked at Senior Crafter and is crafted at Worktable III using 1 Mini Reactor + 4 Coal + 3 Alloy. Building Furnace III therefore requires you to already have an Energy Converter producing Mini Reactors, plus a stockpile of Alloy from Furnace II. Eternal Alloy production cannot begin until Furnace III is online, regardless of how much Aurorite you have stockpiled.

Major Uses

The Electric Drill and Chainsaw share their entire material requirement structure. If you intend to craft both, gather enough Aurorite for 12 Eternal Alloy plus the matching Meteor Plank, Chip, and High Performance Wire Set requirements before starting either build.

Tips

• Plan around 12+ Aurorite per tool. Conversion rates from Aurorite to Eternal Alloy will use multiple raw ore per output. Mine a full deep-forest stockpile (40 to 60 Aurorite) before committing to both endgame tools.

• Furnace III is the bottleneck. Build Furnace III before farming Aurorite at scale. Otherwise the ore sits in inventory while you finish the upgrade.

• Pair with Meteor Plank runs. Both endgame tools also need Meteor Plank. Aurorite mining and Meteor Wood harvesting overlap in deep zones, so plan one expedition for both.

• Save Aurorite for Aurelis gifting. Beyond crafting, raw Aurorite is the loved gift of Aurelis the chef. A few extra ore cuts save a separate gift run.
