Enhancement:Shroud of the Vampire

You shroud yourself with negative energy and assume many traits of a vampire. While in this form, you gain +2 Strength, +2 Charisma, and using your dominating powers, generate 25% less threat from spells and attacks, and +2 to the DC's of your Enchantment spells. When making unarmed attacks, you deal 1d6 Constitution damage from blood drain on critical hits, and your unarmed and melee attacks heal you for 1 point of negative energy damage. You have +100% critical hit resistance, are healed by negative energy, and are unaffected by positive energy or repair effects, but take quadruple damage from light effects. You are considered undead rather than your original type for the purposes of most effects. This ability costs 100 spell points to activate.
