Romulus Nightshade
"Excuse me? We are no "Draculas" we kill people to feed and as punishment for their crimes; the was-man below me has commited adultary, whatever is left of him is in the bushes alone with the ugly fat whale he was with." Romulus said sneering at the fakeling.
"I've had enough of your cockiness...and as if to call on others to beat only two "trash lonely vampires..." " Romulus said.
At that precise moment, Romulus sent his hand out in a taunting way of course in a Force Choke manner, channeling his Vitae in that hand. Unknown to this poor vampire he sent his channeled Vitae towards the youngling's throat, due to this technique and Vitae being invisible, the vampire was unable to breath at this moment, being choked Star Wars style as, logically, there could be no way to counter this, seeing it for the first time and of course being an unexpected attack. Breathing became hard for Otto, his face turned red and gagging noise would most likely start to produce from your throat. You would just be there, gagging as you struggled to break free of this unknown and supernatural force Romulus controlled.
(This is an example of using Vitae, though it pretty much is an autohit, I won't kill, and you can get out of it as well obviously. The reason that this can't be dodged is due to the fact that no one would attack like that nor should it be possible. Think of True Vampires like demons from Hell or Angels from Heaven, depends on their morality. I'm not saying it is a CONFIRMED autohit, if you can dodge it, AWESOME! You found a loophole and I can improve my tactics!)
