The saguaroi expels a spew of needles in a 30-foot cone. Each creature in that area must make a DC 15 Dexterity saving throw, taking 11 (2d10) piercing damage on a failed save, or half as much damage on a successful one. Additionally, creatures that fail their saving throws have their speed cut in half. A creature with its speed reduced like this must succeed a DC 16 Constitution saving throw at the end of each of its turns in order to regain its natural speed.
