OK so I am level 7 and I just killed Jarl. That was kinda tough. Used several health potions. I just descended into a Gold Mine.

So... any tips?

Here's some quick questions:
1) The health and mana potions seem to be full and almost empty sometimes. Why?
2) I am playing a Warrior. Do I need to put any points in Int?
3) Should I be able to run through the Gold Mine?
4) Where do I turn in the quest for defeating that one-eye or one-tooth guy I just defeated?

Thanks!
