Description

Phaerminn are repulsive aberrations of intense psychic power (originally from D&D 4E).

Lair and Lair Actions

Phaerminn live in the crumbling ruins of their lost empires. Sometimes beneath the desert sands or sometimes in the Underdark, where their psychic power dominates. On initiative count 20 (losing initiative ties), the phaerminn can take one of the following lair actions. The phaerminn can't take the same lair action twice in a row.

  • High-pitched psychic vibrations blast from the phaerminn's mouth. Each creature that can hear it within 60ft. of it must make a DC 17 Constitution saving throw or take 10 (3d6) psychic damage and become deafened for 1 minute. On a success, the creature takes half the damage and isn't deafened.
  • The phaerminn uses its innate spellcasting to cast a spell.
  • The phaerminn teleports up to 100ft.

Habitat: DesertUnderdark
