Intellect Devourer's Prowess

You have developed traits similar to those possessed by an intellect devourer, granting you the following benefits:

• You gain blindsight out to a range of 30 feet.
• As a bonus action, you can sense the presence and location of any creature within 120 feet of you that has an Intelligence of 3 or higher, regardless of interposing barriers, unless the creature is protected by a mind blank spell.
• When you take the Attack action, in place of one of your attacks you can choose a creature that you can see within 10 feet of you that has a brain. The target must make an Intelligence saving throw (DC 8 + your proficiency bonus + your Intelligence, Wisdom, or Charisma modifier [your choice]) against this magic. On a failed save, the target takes 2d10 psychic damage and its Intelligence score is reduced by 1d4. If this reduces the target's Intelligence to 0, it is stunned until it regains at least one point of Intelligence, such as through the greater restoration spell.
