So I'm considering playing a Swashbuckler, but I have a question. For the sake of simplicity, we will assume the character has enough panache to take the actions described. The character is assumed to have the feat Combat Reflexes and a Dex of 18.
Assume the character is standing at one end of a 30' long hallway, 15' wide.
There are three enemies evenly spaced with two on the left side and one on the right.
If the character walks down the middle of the hallway and decides to use the Deed: Opportune Parry and Riposte.
Assuming the Parry on each AoO successfully negates the enemy attack, would the character be able to use multiple immediate actions to attack (Riposte!) each enemy as he walks by them?
Or can a character take only one immediate action per turn?
