Once attuned to this ring you cannot remove it without finding someone capable of breaking your bond to it (DM's choice). While in the presence, within 150 feet and not behind total cover to be exact, of Aberrations, Fiends, or Undead the ring will glow and you will hear a small ringing sound in your ear making it hard to hear anything but the detected creatures and your vision blurs everywhere except where the detected creatures are, this causes your heart to race and gives you disadvantage on any wisdom checks, intelligence checks, or their related skills against anything but the detected creatures, this effect stacks with the number of detected creatures around, once the number of creatures exceeds 5 you begin taking psychic damage equal to the number of detected creatures every 6 seconds (1 round). While an Aberration, Fiend, or Undead is causing these effects you can become invisible to any creature of these types for up to 1 hour, until they are no longer within range, or if you choose to deactivate it, this blocks all vision but truesight and tremorsense (if moving), you can activate this ability 5 times per 24 hours and regain 1d4 + 1 uses every day at dawn.
