Lights Out
Uncommon34.7%ObjectiveOptional
You slit the throat of an enemy who was looking for you.
A stealth throat-slit on an enemy who is actively hunting for you - not just an oblivious guard. So make a bit of noise to send someone searching, break line of sight, then sneak up behind them while they're in that alerted-but-hasn't-found-you state and use the stealth kill. Any bandit camp or occupied building at night gives you clean chances; save beforehand.
