I used to play this game a bit but now I have more free time to play through to the end. I really want to finish and thus I have two questions that relate

1-Is there a definitive faq/guide to completing the main quest only. I want to play the main quest only with a little lvling on the side. Whats happened in the past is that I got side-tracked when doing sidemissions and eventually lost track of game.

2-This one is even more important. What does luck do for combat and skills? I read somewhere that it modifies skills such as +2 per 4-8 lvls of luck. Is that true or is that only with drops/loot. If luck only helps boost loot finds than I need to find a better stat to boost.

Thanks for anyone that can help me with this.

Welcome to the forums. This site has a good basic quest run through:

Luck doesn't affect loot, that was an erroneous assumption made in the early days. Luck adds to all chances calculation formulas.

Usually by a factor between 1/10 and 1/4 depending on the specific operation. For enchanting, for example, it adds 1/4 point of enchanting success for each point of luck.

For melee, 10 luck = 0.8 weapon skill. (luck counts 0.1 and skill counts 1.25)

For comparison, 10 agility = 2 weapon skill
