Blind Fighting

must have proficiency in the Perception skill

Extensive and continuous training in complete darkness or in some cases with the aid of blindfolds, have allowed you to hone your remaining senses to a razor's edge. This specialized combat training has granted you the ability to perceive your surroundings in ways others couldn't begin imagine.

• You develop blindsight up to a range of 20 feet.
• Your blindsight can only work in a setting where your character can use his other senses, like hearing and smell.
• You gain advantage on Perception checks relying on hearing and scent.
