Check the item name first
Players often mix up Ancient Civilization Parts, Ancient Civilization Cores, and Ancient Technology Points. Before farming, confirm whether your blocker is a material in a recipe or a point currency in the technology screen.
Farm repeatable progression activities
Boss and dungeon-style activities are the usual starting point for ancient progression materials. Build a route you can repeat cleanly instead of chasing one risky fight that slows the whole loop.
Plan spending
Ancient progression rewards tend to gate useful systems, so decide what unlock or craft you are targeting before the farming run. That keeps rare rewards from disappearing into low-priority upgrades.
