Level 54, 130k money, console and cheats were not used at all.

The endings are the best:

Spoiler

Wild Hunt - Ciri the witcher, Geralt with Yennefer

Hearts of stone - Olgerd is saved

Blood and wine - Dettlaff is dead, the sisters have made peace

Completed ABSOLUTELY all side quests, orders and treasure hunts, including recipes for all Witcher equipment.

All unknown places marked with a question mark have been passed.

All the best (relic) bombs, elixirs and decoctions have been created (except for the only “Decoction from the Succubus”, for the succubus was spared in both cases). I also learned the recipes for all the colors.

Collected all gwent cards from Wild Hunt + DLC.

Roach is a purebred Nilfgaardian stallion (a dark horse given by Emhyr).

Equipment:

Collected grandmaster witcher armor and swords from all schools (Cat, Griffin, Bear, Wolf, Snake, Manticore) - can be found in Corvo Bianco on equipment racks.

Swords and armor from "The Land of 1000 Tales"

Steel sword from "Hen Haidt", "Arondite".

Spoiler

There is also black heavy armor and a sword from "Tesham Mutna"

"Corvo Bianco" has been completely improved, all trophies and paintings with Geralt have been collected.

The rest includes many different enhancement stones, glyphs, mutagens, ingredients for alchemy and crafting, masks, and ceremonial costumes.
