Blind Fighting

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

• You gain proficiency with the Perception skill and advantage on Perception checks relying on hearing and scent.
• You gain blindsight up to a range of 20 feet.
• Your blindsight only functions when you can use your other senses (hearing and scent).
  • (ex: blindsight may not work inside the area of effect of a silence spell, if the character is under the deafened, or unconscious, or other factors specified by your DM).
