First off let me say that i love the game! Ive been playing it now for just over a week. Trying out different races and sometimes classes to.
I would have to say that the Orc, Argonian & the Kajiit are my choice of races.

Ok now to the questions:

1) Are there any maces worth using & where can they be found?

2) Are there any items in the game that regenerate your health & where can they be found?
I don't need the best because I'm going to be starting a new character again if there are such items that can be found within the first 20 levels or so
was thinking about an Argonian named "Trogdor"!!!! but i think I'm going to have to go with the almighty Orc!

3) how do you listen in on the Thoronir & Agarmir conversation to start the next part of the quest? i always have to stand behind a bush that anyone could easily see someone behind but it works. even when i use a fighter with heavy armor. any advice?

4) are there any mods out there that give night vision?

Ok I think that's it for now. Any thoughts or advice would be greatly appreciated
