List of Contents

The Secret Source Automaton: Overseer Device is located on an isolated island south west of the Atocpan region, which can be reached by swimming after indwelling a Koholasaurus.
Natlan Interactive Map and Location
To reach the boss area quickly, teleport to the waypoint near the Derelict Masonry artifact domain in the Atocpan region. From the waypoint, proceed to the shore where a Dragon Idol is located, then look for Koholasaurus nearby.
Indwell a Koholasaurus and swim your way to the island, make sure to collect Phlogiston particles along the way so you can spam your sprint.
When the Overseer Device boss enters Sweeper Mode, it will generate Flow Momentum and spin around, attempting to hit you with the laser.
During this mode, continue dealing Cryo DMG to the boss until the gauge meter is depleted, which will immediately halt the Flow Momentum. Failure to disrupt the gauge meter will cause the boss to spin faster and fire more lasers.
