SPECIAL ABILITIES

Brilliant Flash (Ex)

Whenever a reefhammer mantis creates a sonic burst, it unleashes a blinding flash. Creatures within 20 feet must succeed at a DC 23 Fortitude save or be blinded for 1 round. Mantis shrimp and sightless creatures are immune to this effect.

Incredible Sight (Ex)

A reefhammer mantis’s eyes pick up colors well beyond those visible to humans, and it can see perfectly in all light conditions, including supernatural darkness. As long as a reefhammer shrimp does not have the blinded condition, it is treated as having blindsight 60 feet.

Sonic Burst (Ex)

A reefhammer mantis attacks with such extreme speed that its pincers issue a concussive blast of light and force when they snap closed. Each time a reefhammer shrimp makes a pincer attack, whether it hits or misses, each creature in a 20-foot-radius centered on the attack’s target takes 3d6 sonic damage and must succeed at a DC 23 Reflex save or be Stunned”>stunned for 1 round. A creature that succeeds at this save is immune to the stun effect from additional sonic bursts from a reefhammer shrimp until the mantis shrimp’s next turn, but it still takes sonic damage from additional sonic bursts. The Reefhammer is immune to this effect.

Shattering Strike (Ex)

A reefhammer mantis deals double damage against objects. When it makes a sunder attempt against an attended object, it affects the creature bearing the object with its sonic burst ability.
