You master the ability to investigate to find items of importance and interest or find tracks and clues. You can also perceive sounds much better than others and can determine exactly where they come from. 

• Increase your Intelligence score by 1, to a maximum of 20.
• You gain proficiency in Investigation and Perception. If you already in either of the skills, you add double your proficiency bonus to checks made with them.
• You gain advantage on Investigation and Perception checks.

• You gain the ability to peer at a creature and magically discern how best to hurt it. As an action, choose one creature you can see within 60 feet of you. You immediately learn whether the creature has any damage immunities, resistances, or vulnerabilities and what they are. If the creature is hidden from divination magic, you sense that it has no damage immunities, resistances, or vulnerabilities.

  You can use this feature a number of times equal to your Intelligence modifier (minimum of once). You regain all expended uses of it when you finish a long rest.
