100% Save File for Thymesia. It has everything and everything is maxed. Level 50, all plague weapons & potions fully upgraded. All story & lore pages. All items & ingredients. Literally everything possible and all of it is fully upgraded to the max level possible. Some level respec items too. And, of course; all levels 100%ed and enemies defeated.
Done over 25 hours of gameplay (10 hours of farming). I DID NOT Use any cheats, hacks, mods or trainers! Only unaltered vanilla game.

Save Files are stored at \AppData\Local\PlagueProject\Saved\SaveGames\xxxxxxxxxx(random number)

INSTALL IT THIS WAY: Download the other file 1.1 version. Replace your DeviceSpecificConfig.sav inside SaveGames with mine. Copy the long number folder's name/number that's there, or just remember it or write it down. Now cut that numbers folder out or delete it, and paste my long number folder there instead BUT rename it to what your folder's number was!
.
TL,DR: Inside AppData\Local\PlagueProject\Saved\SaveGames there is one numbers folder and one DeviceSpecificConfig.sav file. Delete that sav file or cut it out somewhere else and paste my DeviceSpecificConfig.sav there instead.
Now, copy the "name"/number of that long number folder or just write it down or remember it. You will need to cut that folder out somewhere or just delete it. Now place my long number folder there instead BUT you have to rename my folder that you just placed there. name it to whatever number Your old folder was.

p.s. someone asked me if I broke 1000 barrels during play. I don't think I have but it's probably really close to since I broke every single barrel in game at least once or twice. if you need that achievement then I suggest going to very first stage of sea of trees and just destroying barrels there for a few moments.

Please do let me know if there are any problems in the forum's comment section and feel free to ask me anything.

Hope you enjoy! Cheers ^^,

OLD (DOESN'T WORK APPARENTLY):
Cut out your save files somewhere else in case you want to use them later. If not then just delete them all. Then place all of my files there
(into the random number folder inside SaveGame).
Of course, first unzip my folder you downloaded with 7zip or something, or you can just enter it and copy/cut the files from inside there.
Really simple really. It should work fine (seems it doesn't, use suggested new way above).
.
TL,DR; 100%ed save with all stuff and everything maxed. Just replace your files in random number folder with mine (AppData\Local\PlagueProject\Saved\SaveGames\random number.



P.P.S. 
In optional files I just shared my whole numbers folder in case you have to rename it to same number as mine.
I also shared my DeviceSpecificConfig.sav file that is outside of the numbers folder in case this was needed as well.
Maybe you just need to replace your DeviceSpecificConfig.sav outside the numbers folder inside SaveGames folder with mine.
Maybe you need to rename your numbers folder to what my folder is numbered or just replace that whole folder with mine alongside the DeviceSpecificConfig.sav that is under it.
To be honest, I am not entirely sure.
