A relatively simple way to harvest infinite golden eggs, with patience.
Setup
This will be a grind, so to set this up you will need:
- Tides of the Foscari DLC
- To have gotten to the Abyss Foscari level
- Unlocked Maruto Cuts / broken the seal in Abyss Forscari
You want to start the level on Endless for the best results.
The Grind
To start the grind, choose Endless mode on Abyss Forscari.
From the start, head straight south until you reach the bottom of the map.
Turn left, and pass by the waterfalls. If you have not broken the seal with Legionnaire as Maruto Cuts, then you will find the Seal of the Abyss here. Once the seal is broken, continue.
Continue left all the way until you reach a wall. Follow the wall upwards, around the turns and corners until it flattens out.
In the flattened area, press against the wall and walk upwards. Eventually, you should reach a false wall that you can enter. Some attacks will be hidden by an invisible walkway as you pass by, if you see this, then that is where the corridor is.
[In the photo, a chest spawned right where the door is.]
You will find a long corridor with a waterfall above you. Press on to the left.
Once you enter the chamber, head south.
You will eventually reach a room that has arches/gateways leading to it. In this room there is a patch of ground that has skulls arranged in a circle.
In this room, miniature Masked Guardians/Atlanteans will spawn. When these are killed, they will drop Golden Eggs.
On Endless mode, the Atlanteans will continuously spawn, meaning you can AFK farm for infinite eggs.
