I haven't tested it, and I did see people say it didn't work as intended, but Fleet Footed seemed to make a difference back when I first took it, but maybe it was just placebo.
Niflgaardian armor is probably the best looking armor in the game, also reminiscent of Witcher 2. In general I think player armors looked better in the prequel. I also kind of miss the more gaunt Geralt, but I guess he's gained a few pounds with age. Ursine looks great especially in standard and superior versions, and in cold weather, but it's a bit bulky for a Witcher armor.
Is your two alchemy points in Frenzy?
