[IWD2]What does "luck" actually do?

[Klorox]

I read all about luck in the game, but have no idea what it actually does.

Think of it as an "improved" +1 to every die roll. It also increases the frequency of critical hits.

The spell is nice (I always use it for Battle Squares), but the duration is too darned short. I wouldn't use it except at high levels or when you're trying to pump your tanks full of every beneficial spell for a very tough fight. Artifacts that boost luck, on the other hand, are very valuable, and a bard's best combat song before lvl 11 is Tymora's Melody, a luck-boosting song.

Unlike all the + and - modifiers, luck affects the die itself.

So if you have + 1 luck, it means that every side of your 20 sided die is increased by 1. So 1 becomes 2, 7 becomes 8... etc... 20 remains 20 since you can't cross the limit. So although unlike a regular +1 modifer, a +1 luck doesn't get you +1 on a 20 roll, luck is much better because now you don't have a 1 on your die so you can't score critical misses, and you have two 20's so you score critical hits twice as often.
That affects all your dies, not just d20.

Similarly however, if you get bad luck (getting drunk, for example), with -1 you no longer have a 20 on your die, so can't score critical hits, and have two 1's so score critical misses twice as often.
