Soul Stone

What drops it

 * Shiro'ken

Festival collectors

 * You could exchange these for various party, alcohol, and sugar items during the Farewell to Gaile event in 2008.

Locations

 * Unwaking Waters (explorable)
 * Exit from Harvest Temple, defeat all Shiro'ken on the way to the res shrine, resign, and repeat. You will only face Warriors, Rangers, and Assassins here, so anti-melee is highly advised.


 * Raisu Palace (explorable)
 * Exit from Imperial Sanctum and simply defeat every foe you see. Remember that you can obtain a Celestial skill from Kuunavang.

Solo farming

 * The 55-monk build does not work due to the shiro'ken's life stealing skill Song of the Mists.
