Right now there isn't any particular "Vamp-out" build for the Dhampir race; Myself and a few friends would like to hear you thoughts on an optimized "Dhampir" class archetype:
A rogue who combines stealth, sneak attack, and Fang bite...
A Necromancer who augments the vampire side rather than "hiding from melee"...
A Sorcerer undead bloodline who empowers the vampire side, again rather than hiding from melee...
and if you dare, a melee character class based on undead not having fear, pain, or fatigue... like a Vampiric Revenant "Fast zombie".
