Run & Retreat are distinct actions.
A question I cannot resolve myself. Player's Manual, p95, says you can choose to Feint or Retreat when you pick the Maneuver card. But in the Maneuver card, it says you can Fein or Run.
Which one is the correct rule? Retreat or Run?
I treat Maneuver as Feint, Retreat, or Run. You cannot Run (move between zones) with an enemy at Arm's Length, only Retreat, and Hidden Combinations requires the defender be in range of the attacker's weapon (and with weapons like Staff or Spear this can be Near range). There's still some ambiguity (and I'm not sure if or where it's been clarified), and I'm not sure this is the best
way to treat it, but I currently allow Maneuver for those 3 distinct actions (Retreat being either unnecessary or required, and Run being mutually exclusive).
