The Prophecy of Sotek is a unique campaign mechanic to the 
Cult of Sotek faction added in in The Prophet and the Warlock DLC. It is closely connected with the Sacrifices to Sotek mechanic, as this mechanic unlocks the next tiers in that one.
Overview[ | ]
Tehenhauin believes that with sufficient sacrifices, the serpent-god may yet return, bringing salvation to the Lizardmen and the extermination of the Skaven. Tehenauin will be issued with a series of unique missions, the completion of which grants access to new forms of sacrifice. When performed, these reward Tehenauin with unique banners, followers, powerful temporary effects, Regiments of Renown and more.
As Tehenauin and his forces win battles against non-Lizardmen armies, they may choose to mark any post-battle captives as Sacrificial Offerings. As the offerings build, they may be spent on performing the sacrifices accessed by the Prophecy of Sotek missions.
The highest level of sacrifice grants Tehenauin the ability to evoke Sotek himself, manifesting an aspect of the serpent-god in battle to deal devastating damage to his foes.
The mechanic starts as a negative with the Saurus upkeep increase then turns to a positive, and finally a greater positive
