The Morning Stars are new weapons my mod adds to Jade Empire. They were not forged by a living blacksmith, but a dead one. For some strange reason - your heritage as a spirit monk may enter into it - these weapons ended up in the hands of a living being. This unique circumstance gives them some equally unique properties. While you wield these weapons you enter a state between life and death. That makes you as immune to weapons and support styles as ghosts are. The Morning Stars are also the only weapon you can use against ghosts.
Weapon Style Drains Focus These weapons are equally part of the realm of the living as they are part of the realm of the dead. Weapons like these are the stuff of legend among Spirit Monks. Their kind is found in historical records only. And while the records are believed to be accurate, it is unknown how such weapons could possibly come to be. No weapon of this kind is known to currently exist.
You can acquire this style by fighting Zeng Sai in the catacombs underneath the Lotus Assassin Fortress. But since these weapons cannot safely be handled by a living being, you will not be able to use them until you have died yourself.
