He doesn’t like Strange Bun and this can affect your relationship with Krobus. Also, keep in mind that his birthday is on winter one so make sure to gift him something nice.
Schedule of Krobus:
It is very easy to find Krobus because he doesn’t travel. The reason is that he is a shadowy creature and just like vampires, he cannot travel in the sun as well. So you will always find him in the sewers. You can find him and his shop in the sewer grate at the south-west of the town. Just go in the sewer, go a bit forward and you will probably spot him.
