Shadar-Kai Empathic Training

You gain proficiency in the Insight skill if you do not have it already. You add double your proficiency bonus ('Expertise') to checks you make with it.

You can use your action to read a targets emotions and try to get preternatural insight about one humanoid you can see within 30 feet of you. Make a Wisdom (Insight) check contested by the target’s Charisma (Deception) check. If your check succeeds, you have advantage on attack rolls and ability checks against the target for a number of turns equal to your Wis modifier.

You can focus your mind to read the emotional imprints left on an object by sentient beings. If you hold an object and concentrate on it for 10 minutes (as if concentrating on a ritual spell), you learn a few basic facts about it. You gain a mental image from the object’s point of view, showing the last creature to hold the object within the past 24 hours. You also learn of any events that have occurred within 20 feet of the object within the past hour. The events you perceive unfold from the object’s perspective. You see and hear such events as if you were there, but can’t use other senses.
