Ordinary Pebble (Clatterback Cave)

This Ordinary Pebble is found at in a cave full of Clatterbacks in the mountains south of Kennings Lodge in Tiragarde Sound. It is part of the Riddle of Baa'l.

The mouth of the cave at, like many others is covered up by trees and snow. This cave is another location where removing all durability damage equipment is advised, as the Clatterbacks are invisible this time around. Use stealth or invisibility, quickly make for the back of the cave, and look for a pile of giblets between two larger snow-covered rocks. The pebble is between the first (eastern) rock and the giblet.
