The Trollweiss Dungeon is a dangerous tunnel filled with ice trolls. These always appear in groups of four and can hit very high. The entrance to the dungeon is located by the Ice Gate, a few steps north-west of the troll child and his parents. In the north-west of the dungeon is a small crevasse in a wall. When climbed through, you emerge at the brow of Trollweiss Mountain. You can sled down (beware of ice wolves) to get a trollweiss flower or go east to Brambickle the gnome explorer. The dungeon is mostly abandoned.
