For those who are curious, here is the template I've come up with:
-1 Blood Drinker
-1 Claws/Fangs
+1 Human Form
+1 -Involuntary Change (Strong Negative Emotions: Anguish, Rage Etc)
-2 --Upgrades Inhuman Strength to Supernatural Strength
-1 --Berserker (Fists) (Completely Involuntary, Activates on Shift)
+1 Feeding Dependency
-2 -Inhuman Strength
-2 -Inhuman Speed
+3 --The Catch (Holy Stuff, Sunlight)
-2 ---Inhuman Toughness
-2 ---Inhuman Recovery
For those of you who have read the Dorina Basarab books, you'll see how I modeled this off of her abilities.
