Stance of Alacrity p. 65
Your mind and body meld, granting you an edge in combat. You move slightly faster than normal due to a combination of confidence, training, and clarity of mind. This slight edge adds up with each action.
Your mental swiftness translates to physical action on the battlefield. You are constantly on edge, allowing you to react to multiple attacks and threats. Most warriors can only manage a single counter move each round.
While you are in this stance, you can use one counter per round without taking an immediate action. You cannot use the same maneuver two times in a round. In essence, one counter you use during the round does not require an immediate action. If you have already taken an immediate action within the past round, such as casting a feather fall spell, you can still use this stance to initiate a counter.
