Infectious Reposte (3.5e Maneuver)

Oh god it burns, it burns like a sickness!

If a creature makes a successful attack against you, you can initiate this maneuver as an immediate action to counterattack with an unarmed strike (typically 1d4 for a medium creature). You do not provoke attacks of opportunity for this attack. In addition to the damage the enemy must make a Fortitude save or fall ill with a powerful magical curse that acts as if a disease. Immunity to disease does not help against this attack. Victims immediately take 1d6 points of Charisma damage. Each round they must save against the damage until they have succeeded on three consecutive saves. Otherwise the damage can continue indefinately.

If their charisma score drops to 0, they pass into a coma and for all purposes, appear to perish. A DC 25 Heal check will prove they are still alive. After 24 hours, the creature will respawn as an infected lycanthrope of your choice. It will not possess any memories of its previous life, and can only get them back with the effects of limited wish and stronger.

This maneuver is a supernatural ability. It requires access to natural or magical shapeshifting.
