Blood of the Werewolf (3.5e Power)

You eyes turn feral and your hands and fangs elongate and sharpen, the blood of the werewolf pumping in your heart.

When you manifest this power you gain a +4 enhancement bonus to Strength, +4 enhancement bonus to Dexterity, +6 enhancement bonus to Constitution, and a +6 bonus to natural armor. You gain a Bite attack which deals 1d6 points of damage (or 1d4 points if you're Small), + 1-1/2 times your strength, and two claws as secondary natural weapons that deal 1d6 points plus your strength in damage. You also gain scent and damage reduction/silver equal to half your manifester level.

Augment: If you spend an additional 4 power points, you gain the ability to change form into a dire wolf as if using metamorphosis at will and you gain the shapechanger subtype for the duration of this power. For an additional 6 point points spent, this power lasts for 10 minutes/level.
