Starting Location: The Cost of Iron
Investigate the home
Inside the house will be a number of injured peasants, who will tell you about a merchant who deals with the Mongols. They want his iron mark.
Search for the merchant cart
Not much of a search when they give you a waypoint for the target. Head for the waypoint to find a massacre.
Investigate the area further
Examine the bodies in the area.
Investigate the cart
Next look at the actual cart.
Defeat the Mongols
Suddenly you’re attacked by fire arrows. Defeat the Mongols.
Return to the wounded men
Jin fears that the Mongols are searching for the wounded men. Rush back to the house.
Probably not a good sign.
Talk to the peasant who gave you the quest.
Search for Mongol tracks
Look for the tracks outside.
Track the Mongols
Follow the tracks until you reach a house where the bandits are holding the merchant.
Search for the merchant
Spoiler alert, he’s inside. But you’ll have to kill all the Mongols in the area before you can save him.
Rescue the merchant
Once you have cleared the area, free him from his captivity.
Speak with the merchant
Looks like the merchant was blackmailed into working with the Mongols, and his brother has paid the price. How tragic.
