Equip the Spirit camo if available for better stamina recovery
Bring the Mosin Nagant for stamina damage
Use the SVD or other lethal sniper if you want a kill route
Stay prone in the water or on the riverbank to reduce visibility
Watch for the Sorrow’s spirits and move carefully between gaps
Use the Thermal Goggles to spot hazards and spirits more easily
Avoid unnecessary shots to keep your ghost count lower
Let the current carry you forward when possible
Collect the revival pill at the end if you die
If going for non-lethal, keep firing the Mosin Nagant at the Sorrow until his stamina is depleted
If going for lethal, shoot him until the fight ends
