The helpfile says "clever". That's typically a synonmy for intelligent. I have no idea what effect wisdom has, not having looked at the code, but based on my interpretation of the helpfile, I'd say "not much".

I doubt it. Then again, I've never had the legacy. "Surprise" makes me think of attacks like the ones you mention: jack, ambush, assassinate. Possibly also "normal" attacks made by people who are hiding (e.g. dirt kick or trip from a hidden thief or assassin). Though that's just speculation.

Unless there's some hidden counter, legacies are either "on" or "off". I don't believe they're learned like skills.
