Seaweed leshys constantly grow small bulbs filled with air. As a move action, they can detach a bulb and give it to another creature. If consumed as a standard action, this air cyst grants water breathing (as the spell) for 10 minutes. Seaweed leshys can have a maximum of four usable air cysts at any one time, and air cysts regrow at a rate of one per 24 hours.
A seaweed leshy can expel a high-pressure jet of water from its mouth to a range of 30 feet. It must make a ranged touch attack to strike a target—if it hits, the blast deals 1 point of bludgeoning damage (this damage is not modified by Strength). In addition, the creature hit must make a DC 15 Fortitude save or be blinded by the water for 1 round. The save DC is Dexterity-based.
