Power Cells also appear as a quest item in Heap of Trouble, though these are separate from the items collected for Ancient Armory.
There are five Power Cells scattered across the world that must be obtained to complete the Ancient Armory quest, with all but the first one being accessible during main quests.
- Ruins east of Mother's Watch
- Hidden room accessed through a crawl space in All-Mother Temple
- Atop the FAS building at Maker's End
- The Grave-Hoard in a locked room accessed by resetting the mechanisms outside
- In a cave in GAIA Prime
