You have been infested or transfused with a foreign magic from another plane, enhancing you with a 6th sense. 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.
Hostile Takeover. Immediately after you roll a 1 on the d20 for a Perception, Athletics, or Acrobatics check, the 6th sense inside of you flares, seeking to control your physical form. (This is in addition to any other effects from the Nat 1). Make a Constitution saving throw (DC 15) against this magical attack. A failed attempt results the stunned condition until you succeed the constitution saving throw. On and after the 3rd failed save, the foreign magic takes control: you must attack the closest creature with a normal attack and the DC for the next save increases by 1 (Max 20).
