Satisfactory Naval Force – a secret achievement in Genshin Impact from the Wonders of the World section, related to the new region. It's a significant challenge, and upon completion, the player will receive a valuable reward in the form of chests and a couple of Primogems for the achievement.

How to Obtain the Satisfactory Naval Force Achievement

The puzzle is located in the East Slopes of Mont Automnequi. Move from the nearest teleport point and head towards a small island.

Another option is to use the teleporter directly on the island if you have it activated. The puzzle will be between two islands, the large and the small one.

The Hydro Particle collection trial will be in the center of the water area on four platforms. Walk on them and activate the pillar. If there are no platforms, it means you haven't interacted with the purple cluster on the shore that activates the platforms.

Trial 1

Before each trial, you'll be shown the path to fly and collect all Hydro Particles. While flying, you'll be attacked by a cannon, so try not to linger or stand still to avoid getting hit.

In the first trial, you need to collect 20 Hydro Particles in 90 seconds. A wind current will appear in the center of the water area on platforms. Use the glider to reach the necessary height. Hydro Particles will be arranged in a circular pattern – simply fly carefully along the specified trajectory. You'll receive a Common Chest for completing it.

Trial 2

During the second trial, you need to collect 18 Hydro Particles in 180 seconds. Once again, rise on the wind current and move higher using umbrella-shaped jellyfish to lift you. They will toss you up to a higher altitude.

If you fall, it's not a problem. The wind current won't disappear, making it easy to return to the jellyfish. The jellyfish will throw you higher than necessary, so sometimes you'll need to retract the glider and fall slightly to collect particles in the desired row. Once you collect all particles, you'll receive an Exquisite Chest.

Trial 3

The final trial is the most challenging. Walls are added to the wind currents, cannon, and umbrella-shaped jellyfish. You still need to move upward. Floating walls will help you hide from the cannon shots. You can also climb them if you accidentally fall down.

If you reach the top but still have uncollected Hydro Particles, look around carefully – you'll be able to see the entire trial area from here. Once you collect the missing particles, a precious chest will appear (Precious Chest). After this, the pillar will disappear as you've completed all levels.

In total, for completing all parts of the trial, you'll receive three chests: a common one with 2 Primogems, a rich one with 5 Primogems, a precious one with 10 Primogems + the "Satisfactory Naval Force" achievement and 5 Primogems. In summary, you'll get 23 Primogems in just a few minutes. Quite generous.
