Constantine the Great's Crucifix

Origin
Constantine the Great served as co-emperor with Licinius and transformed Christianity into the global force it represents throughout history.

On an outmatched march to conquer Milvian Bridge, Constantine swore he had a divine dream regarding the cross. After a surprising victory, Constantine pledged himself to Christ and began by passing the Edicts of Milan and Nicaea - giving Christians in the empire legal protection and returning past properties. Crucifixion was banned, new prayers were added and the clergy received tax leniency. During his church building spree, the foundations to Hagia Sophia and St. Peter's Basilica first sprung to life.

Historians have difficulty evaluating Constantine's reign because his religious and political policies were so deeply intertwined. Victories against both imperial ousters and tribes secured his reputation as a general, headquartered in old Byzantium. Established laws under his rule gave freedom to worship for pagan practitioners, but did not prevent looting of their temples for riches. Tax laws against the artisan classes were harsh, while he regularly promoted unskilled supporters.

Effects
Wielding by a religious leader induces visions or instructions of holiness, enlightenment and prosperity. By personally adhering to a faith, they can persuade others to believe in the same values - whether it be mechanics of the soul and afterlife or just universal morals.

Continually interacting with people or accomplishing defiant feats will garner more support for the user's lifestyle. Some will try to emulate their new idol's success, such as converting to their faith. If large amounts of governing personnel reach the same epiphany, they become willing to pass legislation meant to unify and uplift their people under a relatable creed.

The populace will become mentally shepherded to overlook any legal issues not concerning the state religion. It becomes tantalizingly simple for leaders to change financial and military policies without major backlash.
