The problem with snaryajenie(School Roach) (The Witcher 3: Wild Hunt)

Theme for people who are familiar with the mod the School of small fry. The problem is this: in the game, in addition to the initial standard equipment, there is a set of armor out of Caer Morhen and therefore its improvement. In Ochsenfurt I found a Superior set of armor, but I have a question: Where the hell to find the initial set of armor?
I beg help!
