i think maybe the issue is that im taking the foil back too late in the campaign looking at those guides

anyone who struggles to get the empress i followed this walk through.

I followed the walkthrough, but the option to mention the hopper from the Withering Palace to Oroi didn't show up. Does anyone have a savegame before this point I could use?

if i still had my hard drive with the save on it, i would have mate.

For those who struggle with this as much as I did (option not showing up in multiple playthroughs, despite following the walkthrough) - I managed to get to the Withering Palace with Oroi and unlock the achievements.

It involves a location teleport hack with Ruinvault (a mod that also enables other enhancements, such as speeding up sailing and conversations). Assuming you are on Windows:
1. Go to https://github.com/EBNull/ruinvault/releases and download the latest full release zip.
2. Extract the contents directly into the game dir, like C:\Program Files (x86)\Steam\steamapps\common\Heaven's Vault.
3. Run the game, go to the Dev menu -> Load scene -> The Withering Palace -> Withering_palace_with_oroi_setup -> select either option (I chose the 2nd one).
4. Do what needs to be done to Six. :)

It's a cheat, but after spending 10+ hours just to hunt down this achievement, and the trigger not working for me, I don't feel bad. :P

Hope this helps!
