Main quest: Recover Key Parts
Your task is to find four altars in which four key parts to prison a demon are hidden. Oscar wants to possess with "his" powers.
It is not difficult. You'll fight few dozens of dwarfs and undeads on your way, but you'll make it. The only problem is a fact that during carrying a part of the key, Baal cannot teleport. Because of that you have to walk through all dungeon.
When you move the third part of key a D.W.A.T. Leader appears nearby an entrance to the dungeon. Kill him. It isn't difficult but time consuming - he has incredibly strong armor.
Transferring the fourth key finishes the mission.
Secondary mission: Rennfield's Book
You'll be visited again by the crazy dwarfs from candles. This time he needs some ancient book for which you'll get resources.
Two parts of book are somewhere in the dungeon. The third part is protected by a riddle.
Solving this riddle is simple. Look how five plates are arranged on the screen above, looking from right. Your path must be the same as their order; otherwise you won't be let in the next room. The book is where Baal stands on the screen above.
Secondary mission: Free Wights
You have to destroy three staffs that bound Wights. it isn't difficult. You'll probably search all possible places in the dungeon.
I didn't get any reward for it.
