This page of our guide to Ghost of Tsushima has a walkthrough for The Cost of Iron quest.
How to unlock: Speak with the man at the Golden Temple.
Where to start: Western part of the Kuta Grasslands.
After reaching the starting point of this mission, enter the house and talk to the two men.
Follow the road until you come across the dealer's destroyed cart. Look closely at all the details.
When you find out who attacked the trader, you will be attacked by Mongols. Eliminate them all, then return to the wounded man.
After another conversation with him, you go on another search. There are tracks in front of the house. Follow them.
You will eventually reach the Mongol camp. Kill them all, then free the dealer in the building. Talking to him will complete the task.
