Method

Mission 1: Lestus watch Go to NPC Lestus on Aruthang mountain and say:

Player: hi
Lestus: Hi, Player.
Player: quest/mission
Lestus: If you're bored, you can look around for my watch, I think those nasty kobolds stole it from me.

Now go to Kobolds cave south-west from Lestus and retrieve watch from chest inside cave. Go back to Lestus and say:

Mission 2: Dwarven bucket Go to NPC Ucat in Aruthang city and say:

Player: hi
Ucat: Player, good day.
Player: quest/mission
Ucat: Actually you could be of service. Since the well is closed, we have to walk out to collect the water and the dwarf who was responsible for this is not coming back ...
Ucat: I don't feel like going out myself but you're a human, fresh air doesn't affect you. Maybe you could go look around for someone... short?

Now go to dead dwarven body near Aruthang lake, use it, go back to Ucat and say:

Player: hi
Ucat: Player, good day.
Player: quest/mission
Ucat: So... what's happening?
Player: the dwarf is dead
Ucat: This is terrible! That's what happens when the dwarf is forced to come to the surface. I guess we'll have to find a new unlucky fellow for that errand. Thanks for help anyway.

Mission 3: Purple mushroom Go to NPC Ucat in Aruthang city and say:

Player: hi
Ucat: Player, good day.
Player: quest/mission
Ucat: Well, you could do me one more favor. You have shown courage to go up, maybe you will be courageous to go down. I'll give you the key to that damn well ...
Ucat: One of the dwarves that worked down there brought me a sample of a strange purple mushroom. Sadly I couldn't grow it, so I need another one. Maybe you can find it. Don't tell anyone you've got this key from me... I'll blame it on alcohol anyway, hehe!

Now use key 3850 leading to well east to Ucat, go through Troglodyte cave, use knife on mushroom to get strange mushroom, go back to Ucat and say:

Player: hi
Ucat: Player, good day.
Player: quest/mission
Ucat: Welcome back! Did you find the mushroom?
Player: yes
Ucat: Great! Now I'm going to plant it and brew an imperial Aruthang ale of it later.
