The helpfiles for the other master edges seem pretty self explanatory to me, but this one is a bit inscrutable. It says "Assassins with this edge enjoy a bonus to their unarmed and punching techniques."

What does this mean?

Does it mean your punches hit harder?

Does it mean your punches will get through defenses more often?

Does it mean you defend yourself better, if you are unarmed?

Some combination?

Something else entirely?

Help!
