Special Traits

  • Amorphous. The ebon ooze can move through a space as narrow as one inch without squeezing.
  • Negative Energy Affinity. An ebon ooze is healed by negative energy attacks and harmed by positive energy. When an ebon ooze is subjected to necrotic damage, instead of losing hit points, it heals a number of hit points equal to the damage dealt, up to its hit point maximum. Casting a healing spell on the ebon ooze inflicts an amount of damage equal to the number of hit points the spell would have healed.
  • Slimy Doom. A creature that touches the ebon ooze or hits it with a melee attack while within 5 feet of it takes 10 (3d6) necrotic damage and must make a DC 15 Constitution saving throw. On a failure, the creature begins to bleed uncontrollably and has disadvantage on Constitution checks and Constitution saving throws. In addition, whenever the creature takes damage, it is stunned until the end of its next turn. The creature can repeat the saving throw at the end of each of its turns, ending the effect on itself after three successful saving throws. The disease can also be cured by a greater restoration or heal spell.
  • Sunlight Sensitivity. While in sunlight, the ebon ooze has disadvantage on attack rolls and Wisdom (Perception) checks that rely on sight.


  • Pseudopod. Melee Weapon Attack: +9 to hit, reach 10 ft., one target. Hit: 20 (4d6 + 6) bludgeoning damage and 18 (4d8) necrotic damage. The creature must succeed on a DC 15 Constitution saving throw or be infected with slimy doom.
