Using a combination of Shadow Pulse, Dark Vision, and Shadow Touch when I got close enough to use it, I stealthily navigated my way through the darkness towards the quickly approaching Vampire Association soldiers.
I used Night Whisper to whisper in their ears, "Got your butt." I made it so it sounded like it was coming from behind them. They turned around in the darkness, with their night vision goggles on but they didn't see me. I was laying flat on the ground over a hundred meters away.
The point of making them turn around was to make them stop moving. It was a lot harder to hit a moving target with blood bullets from a hundred meters than a still one.
I whispered in their ears one at a time, and picked them off, one at a time. I made the bullets pointed and made them spin so they would be able to get through the soldiers' armor.
