Beast of Reincarnation: All 13 Ancient Civilization Zone Strongboxes

There are 13 Strongboxes to find in the Ancient Civilization Zone in Beast of Reincarnation, each containing useful loot like Spirit Stone Ore, Amber, armor pieces and Ancient Books. Unlike the free roam Ogouchi Buffer Zone, the Ancient Civilization Zone requires areas to be unlocked before Emma can advance, and it has both an outside area and an underground area that can be confusing to navigate. This guide lists all 13 Strongboxes in the order they are discovered during the main quest, with maps and screenshots for every location.
