The quest Lost Treasure of King Hundar from Koris Deeprunner in Umbral Grotto takes you to the Secret Lair of the Snowmen where you must help Koris to find the king's lost treasure. The cave is full of level 15 snowmen which attack you with Snow fighting skills to protect their secret lair. You must first find a Dungeon Key and then a Boss Key by defeating Freezie in order to reach the end of the quest. There is an area map you can read that will help you find the key points. Talking to each Beacon of Droknar as you progress helps you to gain Dwarven reputation points. Because of the high number of low level opponents this is a fast and very easy method to gain reputation.
