Seven green pearls stud this silver chain. One is large, and the others are in three progressively smaller pairs. The stones slosh as though filled with liquid.

Each of the seven pearls on this chain can be detached and thrown up to 50 feet. When a pearl strikes its destination, it explodes into a 20-foot-radius, 20-foot-high, cylinder-shaped cloud of acid centered on the end point. This cloud deals acid damage to any creature in the area (Reflex DC 19 half).
A strand of acid pearls has four different sizes of pearls, each of which deals a different amount of acid damage. The two smallest each deal 3d6 points of damage, each of the next larger pair deals 5d6 points of damage, each of the next larger pair deals 7d6 points of damage, and the largest pearl deals 9d6 points of damage.

Prerequisites: Craft Wondrous Item, acid storm (SC 7).
Cost to Create: 5,000 gp (plus 700 gp for base item), 400 XP, 10 days.
