Fragmented Magic

My research has revealed a unique purpose for the prismatic shell. Carry the shell and cast your polymorph spell on the Spitelash in Azshara. If you wait a few moments, the chaotic aura of the shell will cause them to split into several smaller clones for a few moments. Kill these clones as quickly as possible, and the shell will collect their essence. When the shell is full, return it to me.
