It would appear ambush has been changed to work with all weapons, rather than just daggers.
Ambush the target, causing 190% weapon damage plus 699.105 to the target (274.93% plus 1011.863 if a dagger is equipped). Must be stealthed and behind the target. Awards 2 combo points.

Thoughts? Maybe a new pvp opener for non-dagger builds?
