Throwing Stars of Ojy-do

The Throwing Stars of Ojy-do was the name given to a set of five magical stone shuriken associated with the city of Ojy-do in Koryo. They were wielded by the five top warriors of the Fangs of Night ninja clan based there around 1357 DR.

Description
Strangely, these shuriken were carved of stone.

Powers
Once thrown, these shuriken never missed their targets. They inflicted greater injury than was typical, and the victim could fall unconscious for a brief time if they could not resist.
