.. Mandrake root

You should find a mandrake if you search around. ( At the village of Krampus go to the village office and into the basement. The mandrake is captured there. )

It is captured in the cage at the basement of the village office. Blitz is guarding it. Maybe you can get rid of Blitz.

Now you need to get the mandrake cage down.

Next you need to open the cage. ( Use the guard's keys to open it. )
