So i hit level 15 not too long ago, i allways hear about boosting luck with a fortify luck spell before entering dungeons to make it possible to get better loot inside.

so i had an idea, what if i took the birthsign that gave (what was it? 10 luck) and every leveup added one point to luck? do you guy's think that would stand out enough to make a big difference?

Myth...Luck has exactly zero effect on loot.

While raising Luck will not help with loot generation, it can still be beneficial. Increases in Luck act 'behind the scenes' to raise your skills when they are being checked against, which can cause spells to be cheaper than they normally would be to cast and melee weapons to hit harder than they normally would. You will not see these increases on-screen, nor do they count for determining eligibility for a skill perk, but they will be there.

The catch with this is, the higher a given skill gets the less benefit it gains from an increased Luck attribute; combined with the high probability that any skills you actually use to any degree will end up capped, this negates any increases to Luck in the long run for those skills. You will still get the benefits while the skills are not capped though, so it can be worthwhile to raise Luck if you are not trying to cap out skills as quickly as possible since you will retain the benefits thereof for a longer period of time.

Unfortunately, do spread that rumor. But it is baseless. Pretty much every systematic test I've seen shows that Luck has no affect on loot. And that's been my experience. But some people just think it does, maybe because they think it should.
