I started playing again a couple months ago and haven't found a few quests I remember from when this game launched. I don't remember the names of them, but can describe them.

1. First quest (at least back then) where you come across a beholder. He's kind of in this room and you can hide behind some columns while you're fighting him.
2. Cave that has mostly giants in it. They put some of the best drops in the game in the final chests, but then they nerfed them after about a month, because it was way too easy.
3. Castle or church maybe? Had first instance of fire reavers you would encounter. I think you had to walk through some outdoors to get there. Bloody animal skulls on the doors.

Thanks
