I've initially created this mod for myself years ago and while updating it for 4.0 thought someone else might enjoy it too. The mod includes Wild Hunt armor for Geralt and matching armor and accessories for Roach. 

Mod replaces Viper armor (HoS), Caparison of Lament (HoS), Ofieri Blinders (HoS), Ofieri Saddlebags (HoS) and Camerlengo Trophy (BaW). Mod also includes some boosts to Iris and Aerondight.

It is designed as final endgame gear that combines the bonuses of multiple Witcher Sets. Armor can only be obtained by crafting it. You need Diagrams for Viper set, obtained during HoS questline and then you can obtain the set by combining Grandmaster tier Bear, Feline, Griffin and Manticore sets. Items for Roach are obtained the same way the items they replaced are obtained.

Bonuses in NG version are comparable to combined aforementioned sets. Bonuses from NG+ version are a bit higher than any set available in the game, however upgraded set is obviously available basically only after mostly completing NG+ and serves mainly as sort of victory lap outfit after beating the game.

NOTE! Final version of the mod modifies Witcher Gear set bonuses so that acquiring set bonuses for ALL Grandmaster sets requires only two items from the set. If you don't like this I left old version of the mod available in downloads.

If you wish to use console to spawn the items instead of obtaining them in the game use the following codes: 

additem('EP1 Witcher Armor')
additem('EP1 Witcher Pants')
additem('EP1 Witcher Boots')
additem('EP1 Witcher Gloves')
additem('Devil Saddle')
additem('Ofir Horse Blinders')
additem('Ofir Horse Bag')
additem('camm_trophy')
additem('Olgierd Sabre')
additem('Aerondight EP2')
