Blindsighted (5e Feat)
From D&D Wiki
Prerequisites: Wisdom 13 or higher
You've trained your senses to allow you to perceive your surroundings without sight. Your heightened senses give you the following benefits:
- You gain an advantage on Wisdom (Perception) checks that rely on hearing or smell.
- During a short or long rest, you can attune yourself to your senses, as if attuning to a magic item. You gain blindsight in a radius of 30 feet until you complete a short or long rest that you do not spend attuning yourself in this way. You lose this benefit while you are deafened.
