Sunseeds (Su): A giant sunflower may fire up to four of its seeds each round as special splash weapons with a range of 100 feet. A ranged touch attack roll is required to strike the intended target. The giant sunflower may spread these attacks among multiple targets as it desires.
Each seed explodes in a flash of light upon striking any hard surface, dealing 1d4 points of damage (1d6 damage to undead). In addition to its regular damage, it deals 1 point of splash damage. A creature particularly vulnerable to bright light takes double damage, while a construct or inanimate object takes only half damage. The save DC is Constitution-based.
A giant sunflower possesses 24 seeds. It produces new seeds 24 hours later. A giant sunflower that fires all its seeds wilts and dies immediately.
