Start with 50 luck baseline, affects probabilities like lockpicks breaking and arena bets working in your favor. The real value kicks in above 50, where every 10 points grants +4 to all skills even past 100 cap, which is pretty significant for overall character growth. Watch repair hammer success rates closely, at 100 luck with 30 armorer you'll get medium break chance versus high chance at just 1 luck.

Leveling luck costs double the attribute points compared to others, making it a serious investment choice. For perspective, pushing from 50 to 55 gives +2 to every skill in the game, which adds up fast if you're thinking long-term. Maybe interesting - weapon effects like mehrunes razor trigger more often with higher luck.

For focused builds rushing specific combat or magic skills, probably skip early luck investment. But if you're playing a jack-of-all-trades character, or plan to dabble in everything, gradually increasing luck pays off nicely. The probability boosts and hidden skill bonuses really shine when you're doing a bit of everything, especially if you spend time lockpicking or making repair runs.
