Sleuth

You have a knack for uncovering secrets and solving mysteries. You gain the following benefits:

• Increase your Intelligence or Wisdom score by 1, to a maximum of 20.
• You gain proficiency in the Insight, Investigation, or Perception skill (your choice). If you already have proficiency with that skill you instead gain expertise with that skill, which means your proficiency bonus is doubled for any ability check you make with it. The skill you choose must be one that isn’t already benefiting from a feature, such as Expertise, that doubles your proficiency bonus.
• Once per short rest, you may reroll one of the dice on an ability check made to overhear a conversation, decipher a code, or follow a trail of clues (such as drops of blood or footprints on a dusty floor).
