Titanium Ore can be found in high quantities underground on planets of Risky or higher difficulties, and cannot be found on planets with a lower difficulty than Risky. Mining in Eccentric star systems will yield the most Titanium Ore. The ore can be found in chests, and as a rare drop from certain hostile monsters.
Titanium Ore is required to make Titanium and Durasteel weapons, armor, furniture and tools.
*Update Eccentric Stars was renamed to Temperate Stars.
