How to Get to The Secret Source Automaton: Overseer Device

Indwell a Koholasaurus and Swim to the Island

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.

How to Beat the Secret Source Automaton: Overseer Device

Disrupt the Flow Momentum with Cryo Attacks

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.

Bring Cryo Units

When dealing with the Secret Source Automaton: Overseer Device, a team with Cryo units is your best bet for disrupting the boss's high damage attacks.

Still, you can bring your best DPS to easily inflict a barrage of damage to the boss and simply have a Cryo unit ready when the boss begins to generate Flow Momentum.
