Mongol Helmet is one of the 50 Mongol Artifacts, pieces of the invaders' culture and warfare you can study. It sits at Frozen Forest Crossroads in Kamiagata, and finding 20 artifacts counts toward the Know Your Enemy trophy.
Head to Frozen Forest Crossroads in Kamiagata and search the area for the item. Frozen Forest Crossroads is a Mongol-held territory, so expect to fight or sneak past guards before you can search it.
