Dagnor's Cauldron is a rugged basin built around a deep central lake, best known for the sunken entrance to Kedge Keep at the bottom of the water and the haunted Estate of Unrest on its shore. Aqua goblins prowl its slopes and make it a lively mid level hunting ground.
The aggressive aqua goblins roam widely and are hard to spot against the terrain, steep cliffs can inflict severe fall damage, and the deep lake risks drowning while both Kedge Keep and Unrest are much higher level than the open zone.
Bring Enduring Breath and Levitate for the lake and cliffs, hunt goblins around the water through the teens and twenties, and use Spirit of the Wolf with sneak to move safely.
