This is my first time playing the game. I am using a two handed warrior. I'm level 14 and still having a hard time doing quests that you have labeled level 10. Could be my build. I don't know. I love the game but I think I must be doing something wrong if I'm level 14 and can't complete quests I should have completed a long time ago according to this list.
I'm having similar difficulties with Forgotten Lore 2. I'm a level 8 rogue with decent equipment, including the Lesser Ring of Death. I have Grissenda (level 6) and a mercenary. I'm trying to get Zaniel's Journal from Deadwood, and can't make it in, even on Casual difficulty, with a Potion of Death Ward. The monsters near the center are level 9, so I guess that's understandable, but this list declares that this quest is level 4! How can that be right?
