I mean, in the village itself there is a house inside which there will be an NPC, talk to him, he will open the entrance to the basement and there will be a test. If I remember it correctly, it's some kind of stable and there are 2 girls there.
Yeah I found it thx, the quest was very confusing me since it said near willo wisk not in the willo wisk village so my first thought was that trial underground thingy
