Ah, but "chance favors the prepared mind", so it IS possible to improve your luck.

[hyperpallium]

But is it a "skill"?

[lstodd]

It is better called "ability". And "luck" is better called "recognizing an opportunity".

If you're unable to utilize an opportunity, which takes skill, or are unable to recognize an opportunity, which also takes skill, you're out of luck.
