Armband of Magical Awareness

Path of the Wild Magic Barbarian only.

While wearing this magical steel coloured armband your Magical Awareness ability lasts for 10 minutes. In addition, you can end the ability early to analyze and identify weak point in spellcasters. If you do, Magical Awarness vanishes and you cast Hunter's Mark on anyone within 90 ft, but the target must have access to magical abilities (this include spell-like abilities). If they do not have any magical abilities the spell fails. You can use the Hunter's Mark ability once per long rest.
