Ki Sensory System

For whatever reason you have been permanently blinded. However, through rigorous training, you have been able to unlock the ability to sense the world around you using ki. You have also improved your other natural senses to super human levels.

This provides the following benefits:

• Acute Touch: Your sense of touch is so acute, you can feel and discern faint differences on a surface, allowing you to read by touch. Your skin is equally as sensitive, allowing you to feel minute pressure and temperature changes around you, allowing you to sense if someone is nearby.
• Heightened Hearing: You heighten hearing allows you to hear subtle sounds. You can mentally block out sounds to hone in on specific ones. You can even hear a persons heartbeat from 10 feet away, or people whispering in other rooms. Gain advantage on perception checks related to sound.
• Heightened Smell: Your heightened smell allows you to recognize, identify and discern differences and locations of creatures and objects based on scent.
• Illusion Awareness: You are grounded to the reality of the physical world and illusions that rely on sight, have no effect on you.
• Blind Sight: You can perceive your surroundings without relying on sight, within 60 ft.
• Tremor sense: You can detect and pinpoint the origin of vibrations within 10 ft, provided that the monster and the source of the vibrations are in contact with the same ground or substance.
• Echo: You can emit waves of energy that act like echoes when combined with ambient sound allows you to sense the environment around you. These waves bounce off of the world around you letting you locate and identify objects.
• Person Identification: The combination of heightened senses allows you to identify people.

In summary with your senses combined you have the ability to paint a fairly vivid image of your world around you. Although you cant discern color and value, you can determine shapes forms and locations of creatures and objects around you, regardless of the lighting condition.

And the following detriments:

• Vulnerability to Thunder Damage
• Blind: You permanently have the blinded condition, having no ability to see colors or value.
• If something were to make an extremely loud noise, it might hinder your ability to "see." (DM's Digression)

Note: This feat will require some coordination between player and DM. It is up to the DM to discern exactly what you can or cannot see.
