It's just another day?

When you get back to the party, the nice ambience is gonne and been replaced by the dark ambience of death.
It was all an illusion created by the vampire. You walk at the other end of the room, where two swords are on the wall. You take one sword, it might be strong enough to brake the floor.But when you turn around, a vampire army is waiting for you. Wow! Back up.

What do you do?
