I do play vampires according to Vampire The Masquerade clans; build their powers and flaws according to that.
So I play different type of vampires. A ruler type of vampire (Ventrue) with compel and refined taste, an artistic seducer type of vampire with obsession (Toreador), an ugly monstrous vampire who can hide behind shadows (Nosferatu), a rebel fighter type (Brujah), a vampire with erratic trait (Malkavian), with Animal enthusiast trait vampire who can transform into bat (Gangrel)
For spellcaster vampire (Tremere), I need zer0's mod though.
