Each non-aberration, non-fiend within 300 feet of Cthulhu and aware of him must succeed on a DC 27 Wisdom saving throw or become frightened for 1 minute. A creature that becomes frightened drops to 0 hit points and begins dying. A creature that is immune to being frightened and fails the saving throw becomes incapacitated for 1 minute; at the end of each of the target's turns it may make a new saving throw, becoming no longer incapacitated on a success. If a creature's saving throw is successful or the effect ends for it, the creature is immune to Cthuluï¿1/2s Unspeakable Presence for the next 24 hours.
