Divinity: Original Sin Enhanced Edition

Not far from the goblin village, under a tree we find a hatch into the Maradino cave. In the cave we find Maradino's documentation, opening a secret passage with the help of a book that sticks out of the bookshelf. The documentation describes how to get into the troll cave. We approach the cave and read the documentation in the ring of mushrooms. I managed to collect them before, but the outline of the circle remained, so we read the book and the entrance to the cave is open. Inside we kill King Gungir, collect tenebria ore and treasures. We go to Archibald. It also stands near the goblin village. We talk about the death of the king and the trophy is yours.
