  • Enhanced Perception. Hundred-eyed demons are highly sensitive to motion and tremors. They have advantage on all Wisdom (Perception) checks due to their multiple eyes and their other enhanced senses.
  • Sustenance-free. Hundred-eyed demons do not need to eat, sleep or breathe.


  • Bite. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 32 (6d8 + 5) piercing damage plus 13 (3d8) poison damage. The target must succeed on a DC 17 Constitution saving throw or be poisoned for one minute. The creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. In addition, the creature is grappled (escape DC 17). The hundred-eyed demon cannot make bite attacks when it has a grappled target, but it can continue to inflict 13 (3d8) poison damage on its turn upon its grappled target.


The hundred-eyed demon is a massive armored centipede with a thick carapace studded with dozens of tiny black eyes. Its mandibles clack with deadly intent. Sleepless, mindless, and infinitely patient, hundred-eyed demons lurk in silent darkness awaiting intruders, then attack from the shadows. Their senses are incredibly acute, allowing them to detect vibrations and movement from a great distance and quickly pinpoint the source of the disturbance.
