Bestiary 2 | Monsters | Yrthak | Special Abilities | Blind
A
yrthak sees and senses exclusively through its
blindsight ability, which is based on sound and movement—beyond 120 feet, it is considered
blind. A deaf
yrthak is effectively
blinded as well except against adjacent foes—its weak eyesight functions enough for it to attack targets this close, although in such cases these creatures still gain the benefit of concealment (20% miss chance) because of the creature's poor
vision. It is invulnerable to all sight-based effects and attacks, including gaze attacks.
