Snake Reverse Molts (3.5e Maneuver)

With a smooth slice and step, you chop your victim in half and step into their clothing.

Make an attack against a target within 5' for 9d6 extra points of damage. If the target is reduced to 0 or fewer hit points from this attack, you may swap places with the target and make a Disguise or Move Silently check to disguise yourself as the target and the target as you. Any creature who fails to see through your disguise will see that the target has killed you.
