Death's Arrival

You designate a target you can see within 30 meters. You instantly appear behind them and make a melee attack that automatically hits and critically strikes. This attack ignores all Resistances and armor. If the target is below half HP, they must succeed a RES Save against your AGI Check or be killed outright. If the target's TR exceeds your level, they gain a bonus to this save equal to the difference. On a successful save, the target takes additional damage equal to three times your level. Regardless of outcome, you may immediately perform Vanishing Act without requiring a kill.
