Secret Source Automaton Overseer Device boss location and how to reach

The Secret Source Automaton Overseer Device boss is on the small island southwest of the Atocpan region in Natlan. Unfortunately, no land connects it to the mainland of Natlan, so getting here for the first time may be tricky. If you have Furina, you can use her Elemental Skill to walk on water and get to the island.

For those without Furina, teleport to the waypoint southwest of the Children of Echoes and head straight towards the shore to find a couple of Koholasaurus near the Secret Source Dragon Idol. Indwell the Saurian and swim to the boss’s island. You will also find a lot of Phlogiston Particles on the way, so you can use the Aquadash skill to get there faster. Once there, unlock the teleport waypoint for fast travel next time.

Tips to beat the boss

You can use brute force to beat the Secret Source Automaton Overseer Device boss in Genshin Impact. However, during the battle, it may enter the Sweeper Mode, during which it will start using hydro pump attacks, and these attacks also get stronger as time passes. Furthermore, the boss’s elemental resistance significantly increases in this state.

The only way to stop the boss is to use Cryo attacks, so it’s best to use a proper Cryo team or at least bring one unit that can perform fast Cryo attacks, such as Ayaka or Wriothesley.
