NIGHT GUES
Thats why telling complete a set first
Very true. That mode will kill your resources (potion used).That's why I told everyone to complete one. Even if not a full set or different types you are using but all you are wearing are uniques from armors to accessories, you may get through. Nevertheless it's much easier and enjoyable with a complete full set with set effect active (5th skill) 😎.

Very frustrating to complete cause it's very rare but possible. I have lots and lots of unlucky days in the shop and in drops before I completed one. Takes me several months to do it.
