How to farm Silver Ribbon?

[Vexillarius]

Do i need to progress all the way to malefic palace and spawn shattered gallery or great hall there? I have tried spawning shattered gallery in beatific palace but it doesn't seem to spawn the ribbon event. Wiki and videos say something about it only appearing at night time or in the dark so i guess that means after i can change palace state?

There honestly isn't a good way to farm a specific event. What locations you get are RNG and what special events you get inside those locations are also RNG.

Your best option is to use this tool's world analyzer and screen your adventures before you run them: https://github.com/Razzmatazzz/RemnantSaveGuardian

When you roll Losomn, the statue event can be present.
If the statue event appeared in the Shattered Gallery or Great Hall, it will always give you the Silver Ribbon.
If the statue event appeared in the Council Chambers or Gilded Chambers, it will always give you the Golden Ribbon.

It's only RNG when you create the world. There is nothing you can do to influence the result.
The only thing to make this easier is to use the Save Guardian tool to know if it's a roll of the world you want (else, you reroll).

The tool: https://github.com/Razzmatazzz/RemnantSaveGuardian
The tool analyzes your save file. So after creating a new adventure (or campaign) at the stone, you need to leave the stone and touch it again to make the world save with the new data. On update of the save file, the tool automatically refresh the data displayed.

Ok, doesn't seem like any extra dungeon spawn in the malefic palace area. All the areas that have magic doors just have chests in the other palace so it must spawn in the beatific palace.
