Awakening of Evil

Rambo1969, you are an example for all of us. The latest missions are incredibly difficult. Few people can even complete them. How many days did it take you to complete the last mission? What difficulty level are you playing on?

(I haven't figured out how to get into the Dwarven treasure vault yet - where the passages are blocked, and I couldn't get into the hero's tomb).

And is it even possible to get in there?
