The dungeon’s front door is approachable from its eastern side. There is a wooden path that leads toward what feels like an abandoned mine. You can’t see it if you come from the nearby road, as it is hidden behind the hill. It turns out that this is a mine, where you can produce an abundance of valuable kwama eggs. If you talk with Ridena Devani in front of the entrance, she can give you the dungeon quest “A Dangerous Breed”.
There is one large dungeon room, with water in it. Head to it – it is located in the southern cave area, on a small plateau in the center of the pond. Watch out for the fall, as this part of the cave is on a slightly lower level than the rest of it. There are no enemies near it, but there are plenty of them on your way there. Some would say even surprisingly more than you would expect in a solo dungeon.
