Starflare Core is the mid-tier crystal smelting product in Starsand Island, fired from Primorite at the Furnace II. Like the other core products it has a refined sibling: 3 Starflare Cores become 1 Starflare Crystal at the Gear Smith, and the two are separate items with separate consumers.

Smelting Recipe
Detail | Value |
|---|---|
Station | Furnace II |
Ingredients | 4 Primorite + 1 Coal |
Output | 1 Starflare Core |
Where to Get Primorite
Primorite first appears at Azure Bay and continues through the deeper Moonlit Forest zones, often alongside Gold Ore. See the Mining Guide for routes.
Major Uses
Clothing recipes. Starflare Core is a staple of Sewing Table outfit crafting, appearing in around two dozen clothing pieces such as tops, skirts, and headwear.
Starflare Crystal refinement. 3 cores refine into 1 Starflare Crystal at the Gear Smith; the crystal form feeds advanced tool recipes like the Chopper III build.
Worktable projects. Mid-tier builds such as the Realm Box call for Starflare Cores directly.
Tips
Budget cores for both demands. Clothing and crystal refinement compete for the same supply; three extra cores per planned Starflare Crystal keeps wardrobe projects from stalling your tool progression.
