Afterimage Walk (3.5e Maneuver)

As you walk, many faint afterimages of yourself appear and follow you, over and over again.

Move your speed and spend some essentia. Any space you occupied during this movement is filled with afterimages for 1 round, becoming difficult terrain. Anyone who enters a space filled with afterimages for the first time that turn takes 1d6 points of force damage per point of essentia invested in Afterimage Walk.

This maneuver is supernatural.
