Do not sneak in broad daylight over an open field - even though you skill says you are likely to succeed, there are no shadows to hide in and you will be spotted.
Shadowdancers, do not, in fact, require cover or concealment according to this passage.
I disagree with that interpretation, because shadows provide concealment and the Shadowdancer has to be close to (or within) a shadow to gain benefits.
