Heightened Senses

Extensive and continuous training in complete darkness, or in some cases with your vision obscured, 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 to imagine.

• You have blindsight out to a range of 10 feet. You gain this benefit only if your other senses, such as hearing and smell aren't impaired. If you already have blindsight from another source, the range of that blindsight increases by 10 feet. If you possess the Rogue's Blindsense feature, the range of your blindsight increases to 30 feet.
• You have advantage on Wisdom (Perception) checks relying on a sense other than sight.
• You have the ability to hear things as minute as someones heartbeat. You have advantage on Wisdom (Insight) checks against creatures within 10 feet of you, provided they have a discernible heartbeat.
