I played this mission a few days ago, it took me about 3 days to finish mostly because some parts of the mission are very hard and frustrating. Let's start with the Inn where the starting point is. If you draw any weapons and attack the inhabitants you fail the mission. But even after you exit the inn on the streets nearby if the inhabitants follow you on the streets you still cannot attack them bacause again you fail the mission. Even if you attack a guard in front of them on the streets the mission still fails. That is very frustrating and has no logic.
Then lets talk about the architecture. The buildings in this city are mostly consisting by cubes with windows only a few are more complex. This is not interesting enough to explore.
Exploring the city itself is more fun, so there are not only bad things.
Then we reach the museum. The building is badly designed in my opinion, with fake doors everywhere, there is only one door that is real and working as a way in. In the museum I had the worst experience in my life when i stole the chalice and die. After the death I was resurected in the land of the death. Lets say that here the experience with a certain stone chair in the middle of a pool of lava is extremely hard and frustrating. Then another frustrating part with the labyrinth with the tree of life. I died there o lot of times and I needed to reload often. We have no weapons here and there are a lot of skeletons who can attack and kill us.
The last part of the mission was again very frustrating, because I finished all the other goals except the loot goal.. I was at 1700 loot and the goal is very high 4000 loot. So i needed to explore all the map again and again in search for every little piece of loot. Not a very fun thing to do.
So in the end I can't recommend this mission, too many bad things that needs to be fixed maybe in a remastered version.

I'm seeing a lot of spoilers here. Not everyone likes reading that before having played the mission.

Sorry for the spoilers.. but I didn't find another way to explain things, and there are no spoilers tags on the site. Or maybe they exist and I don't know how to use them?

I started this mission two times, but, it wasn't my cup of tea. Something feels off, can't lay my finger on it.
