Blindlife Adept

Somehow you have lost your ability to see. However, despite your disability you have thrived, developing a new primary sense you can use to navigate akin to how those who can see navigate by sight.

• You permanently have the Blinded condition, however you do not have disadvantage on attack rolls and attack rolls against you do not have advantage. 
• Choose either Touch, Smell, or Hearing. Your chosen sense is now your "primary sense." When asked to make a perception check using sight you can make a perception check using this sense instead. 
• Losing your ability to use your primary sense gives you disadvantage on attack rolls and attacks against you have advantage. 

Touch: You have an innate aptitude for identifying things via touch. You have developed the ability to identify the natural vibrations created when things move. As these vibrations reverberate around you, you can identify the character of these vibrations and create a mental map of your environment. You can identify minute imperfections in objects and thus can discern between even visually similar objects. You can identify individuals by the weight and nature of their stride. Being in an environment that disrupts your ability to feel these vibrations, such as being underwater, is akin to being in darkness for those who can see. The arcane nature of magical invisibility disrupts your ability to perceive them via vibrations, so they are imperceptible to you as they are to someone who can see. 

Hearing: You have an innate aptitude for identifying things via hearing. You have developed the ability to echolocate. You can make quiet high pitched chirps or clicks and use their echoes to create a mental map of your environment. You can identify minute differences in the sound objects make when tapped and thus can discern between even visually similar objects. You can identify individuals by the sound of their breathing and movements. Being in an environment that disrupts your ability to hear, such as being underwater, is akin to being in darkness for those who can see. The arcane nature of magical invisibility disrupts your ability to perceive them via sound, so they are imperceptible to you as they are to someone who can see.

Smell: You have an innate aptitude for identifying things via smell. You have developed the ability to identify not only the natural chemical compounds in the air, but how they interact with the environment as they waft about. You can use the way smells stick to objects and waft around a space to create a mental map of your environment. You can identify minute differences in the smell objects and thus can discern between even visually similar objects. You can identify individuals by their unique cocktail of odorous compounds and pheromones. Being in an environment that disrupts your ability to smell, such as being underwater, is akin to being in darkness for those who can see. The arcane nature of magical invisibility disrupts your ability to perceive them via smell, so they are imperceptible to you as they are to someone who can see.
