Versipellis Seed (3.5e Maneuver)

The enemies watch in horror as the claws come from inside their body, tearing them apart!

You make a touch attack against any corporeal living creature, causing parts of their body to briefly undergo the lycanthropic curse and start developing incomplete teeth, claws, and muscles which twitch and quiver and try to tear their way out of the body. Your touch deals 1d6 points of damage per level, and the target must make a Fortitude save or become nauseated for 1 round, DC 18 + Str modifier. On a successful save, they are instead sickened. If this damage kills them, the mutation completes all the way and 1d4 versipellis burst from their body, under your control as if you used summon monster. Their bodies are unstable however, and the conjured versipellis only remain for 1 round/level before collapsing into piles of skin and mush.

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