Perceptive (5e Feat)
From D&D Wiki
Prerequisites: Proficiency in Perception
Your ability to perceive the world around you is beyond what most could imagine.
You can add double your proficiency bonus to Perception checks and your passive perception.
Once per long rest, if you fail a perception check, you can reroll it and you must take the second roll.
While blinded or you otherwise can't see, once per long rest you can use an action to gain blindsight for 30 feet for up to 1 hour or until you can see again, whichever comes first. This feature is deactivated if you are Deafened, and cannot be activated while Deafened.
