Shells on the Sea Shore

Objectives
Gather 8 Unexploded Mortar Shells along the beach at Slithering Cove.
 * Unexploded Mortar Shell (8)

Description
I salvaged these mortars from the wreck of our airship when she detonated above Dragonmaw Port. But ammunition is in short supply!

While you're running along the beach, do me a favor and pick up any unexploded mortar shells you find.

Unexploded shells are the best kind - you never know WHEN they're going to go off. Perfect for surprising an enemy!
