Exposure to alien horrors like those of the Far Realm has warped your physical form in supernatural ways. You gain the following features.

Breathless

You can hold your breath for 1 hour.

Extrasensory Perception

You have proficiency in the Perception skill, if you lack it. You also gain Expertise in that skill.

In addition, you have Blindsight with a range of 15 feet.

Warping Flesh

Immediately after you make a D20 Test and roll a 1 on the d20, the aberrant influence infecting your form flares, wrenching control of your flesh. Make a Constitution saving throw (DC 13 plus your Proficiency Bonus). On a failed save, you have the Stunned condition until the end of your next turn.
