Son of Osiris

The Son of Osiris is a Pharaoh upgraded with the Son of Osiris god power - bestowed by worshipping Osiris - gaining a staff and a falcon head. With this upgrade, he retains the powers of a normal Pharaoh, such as empowering and healing, but gains the ability to fire chain-lightning bolts that deal a devastating amount of damage and hit multiple enemies and buildings. The Son of Osiris cannot be healed, and if he dies, you will regain a normal Pharaoh. He is much stronger than a regular Pharaoh, but due to his combat effectiveness and inability to heal, he is a prominent target for players' opponents.

As a Hero, the Son of Osiris deals bonus damage against myth units. As such, he is extremely effective when used against myth unit-heavy armies, though he still deals good damage against human units and even heroes.

The Son of Osiris is a notably effective Titan-killer due to his bonus damage and range.

Interestingly, there exists a glitch involving Osiris' New Kingdom improvement: when the god power is used after the improvement is researched, a third Pharaoh will spawn, totalling two Pharaohs and one Son of Osiris.
