Starmetal Ingot

Starmetal
Starmetal is a fundamental component in progressing further into Astral Sorcery. (Early Mid-Game) It is also the key ingredient for obtaining Stardust.

As of the update 1.12.2 Starmetal Ore is 1 of 3 different ores found in astral sorcery and may change in the future.

Astral Tome Entry
''Most likely, these beams of light could have other uses than looking pretty and tend to have effects on the world generally. How about focusing the light directly onto one mundane iron ore with a linking tool? A source of focused starlight could work, might as well use one of those floating crystals in the shrines that have been found. Giving that one a clear view to the sky might help too. It seems like the iron reflects the starlight back and shimmers slightly blue... Maybe something will change when given enough time...''

How To Obtain
Starmetal is the outcome of smelting Starmetal Ore which is unobtainable through mining and must be formed by a player. To form this ore a player must have obtained the linking wand and lenses and must have a floating crystal exposed to starlight nearby. (Can be found at Ancient Shrines)

Start by right clicking the linking wand onto the floating crystal and then onto a lens that has to be facing a placed block of iron ore, to turn a lens simply disconnect the linking tool from the floating crystal and right click on the lens and right click again onto the iron ore. (Shift + Right click to disconnect)

After a little while the iron ore's colour will have changed to a darker blue, mine it as you normally would do and put it into a furnace.
