A 100% save file with 52LV Geralt before starting NG+, lots of alchemy/crafting ingredients, all Grandmaster sets crafted, every single quest finished (except gwent), every question mark (two are bugged, but done nonetheless) visited, +40k coins, all potions and bombs are excellent, hundreds of mutagens to play with, mutations unlocked. Most of the equipment is located in Corvo Bianco's chest, feel free to check it.
This is your perfect NG+/fun save file you can find out in the NexusMods. I'm using an alchemy/combat build.
VANILLA/HoS/BaW FINISHED AND MAXED.
Ciri became an empress, Nilfgaard won the war with Temeria being an autonomic province. Stayed with Triss. Olgierd lives. Henrietta and Syanna reunited, and alive.
INSTALLATION : Repack all files inside the archive to Documents/The Witcher 3/gamefiles location.
PS. Don't mind the dirt in Corvo Bianco, 'tis but another bug.
EDIT: Forgot to add I haven't touched much Gwent throughout the whole game, sorry!
