The Prophet of Regret is a weak boss mob that rarely spawns. It usually spawns with a group of Honor Guards.
Appearance[]
Regret takes the appearance of a Hierarch wearing a golden crown and often times gray-blue robes. However, sometimes he may spawn with dark green robes instead.
Info[]
The Prophet of Regret was one of the last 3 Hierarchs to lead the Covenant. He led a small invasion fleet to Earth, in an attempt to reach the Ark portal. However, his entire fleet was destroyed, with only his command ship making it to Installation 05. It was there that we was assassinated by the Master Chief, before the Covenant fleet could even stop him. As a result, Sangheili were no longer allowed to be honor guards, and were replaced by several Brutes.
However, the Prophet of Regret was later assimilated by the sinister Gravemind. It is possible that he died along with the Gravemind on the Ark.
