Red Shroud (Su)

At 3rd level, a Red Mantis assassin can create a veil of red mist a number of times per day equal to her Constitution modifier (minimum once per day) as a move action. The red shroud persists for 1 round per class level, granting the Red Mantis assassin a +1 dodge bonus to AC and fast healing equal to her Constitution modifier (minimum 1). This mist cannot be dissipated by wind. If she is slain while this ability is active, she can choose whether to remain corporeal or to disintegrate into a cloud of red mist that leaves behind only her gear, depriving her enemies of access to her remains.
