Cold Adaptation. You're naturally adapted to cold climates, as described in chapter 5 of the Dungeon Master's Guide. You also have resistance to cold damage.

Merchant's Senses. Whenever you perform an Intelligence (History) check, or tools check to determine the origin or value of an object, you are considered proficient in the relevant check and can add double your proficiency bonus to the check, instead of your normal proficiency bonus.

When you reach 3rd level you learn to cast detect magic and identify, but only as a ritual, you do need material components.

Merger Link. Over the course of a long rest you can establish a mental connection with one willing creature that has an Intelligence of 6 or higher. While forming the link the target must remain in your presence at all times. You can then communicate telepathically with your linked partner as long as you are on the same plane of existence or until either of you finish your next long rest.

Mind Reading. While interacting with a target you can see within 30 feet you can non intrusively read their desires and surface thoughts, providing you with advantage on Insight (Wisdom), Persuasion (Charisma) and Deception (Charisma) checks while performing negotiations with the target. Because you only capture their surface thoughts the target is not aware of you scanning them, however people familiar with Dohwar know they have the ability to read minds. You can maintain this ability for 1 minute or until you lose your concentration (as if you were casting a concentration spell). This trait counts as a divination effect. You can't use this again until you finish a short or long rest.
