Like the Sect Token, each pendant has a needle, but it points to the nearest structure of its kind. Only the structures with a boss have one:

• Misty Bamboo Daoist Temple Pendant: a jade disc ringed with bamboo, its needle a small sword (Sensei Yun)
• Yellow River Bandit Den Pendant: a tarnished bronze disc, its needle an axe (the Bandit Chief)
• Alliance Arena Pendant: an azure enamel disc with the three peaks, its needle a spear point (the Captain of the Peak Guard)

Right-click: it searches, then tells the direction and the distance (5 s cooldown). It only works in the Overworld.

Sold by the Alliance Merchant, 128 silver taels each.
