In a valley near the burning pigs is an ambush of a demon and some skelletons. If you press the button, you can see the field of view of the hidden enemies. I casted an ice spell on the position where the enemy will show up. There was no damage and combat did not start, but a message cold or wet was apllied or failed to apply could be seen (sorry, not sure what exactly). You can go up the highest platform at the beginning of the valley and move to the end without starting combat. From there I could start combat by teleporting the demon to me.
