  • Amorphous. The aphasian abomination can move through a space as narrow as 1 inch wide without squeezing.
  • Aphasic Field. The aphasian abomination generates a field of psychic distortion around itself. Each creature that starts its turn within 60 feet of the abomination must succeed on a DC 17 Intelligence saving throw or lose the ability to speak coherently, saying coherent words that make no sense in context instead of whatever it intends to say. If the creature attempts to cast a spell with verbal components, it fails, taking 9 (2d8) psychic damage per spell level of the spell it attempted to cast, and it expends the spell slot.
  • Construct Nature. The aphasian abomination doesn’t require air, food, drink, or sleep.
  • Immutable Form. The aphasian abomination is immune to any spell or effect that would alter its form.
  • Made of Magic. The aphasian abomination is formed of magical energy. It temporarily winks out of existence when inside an antimagic field, instantly reappearing once the space it occupied is no longer within the area of effect. An aphasian abomination targeted by dispel magic takes 21 (6d6) damage plus an extra 7 (2d6) psychic damage for each spell level beyond 3rd, if the spell is cast using a higher spell slot.
  • Magic Resistance. The aphasian abomination has advantage on saving throws against spells and other magical effects.


  • Multiattack. The aphasian abomination makes three Force Blast attacks.
  • Force Blast. Melee or Ranged Spell Attack: +9 to hit, reach 5 ft. or range 120 ft., one target. Hit: 23 (4d8 + 5) force damage.


A swirling cloud of orange-yellow energy moves with deliberate intent. What appear to be dozens of glowing, green eyes and mouths churn across the surface of the cloud as it moves.

A living weapon created during a great war of mages, the aphasian abomination exists to slay spellcasters. Its powerful abilities to attack the speech centers of the mind can break communication as well as stop spellcasters from speaking the words necessary to cast their magic, effectively neutralizing them. Though the mighty magicians that created these magical constructs are long dead, their creations still roam free in the blasted wastes where the war was fought, seeking enemy spellcasters to destroy.

Dangerous Portents. The aphasian abomination’s ability to sense and seek out magic means the area where one is encountered likely contains remnants and relics from the ancient past.
