Game concept
Vizier Succession Score
From the game's encyclopedia
In a Vizierate, the next Vizier is picked based on which candidate has the highest Vizier Succession Score.
Prospective candidates may occasionally try to convince the Ruler to let them replace the incumbent in exchange for Gold.
This allows only landless and Baron-Tier Characters, favoring those with strong Diplomacy, Stewardship, and Intrigue, as well as Traits that make for a good civil servant.
Special Relations with the incumbent Vizier or the Liege's Spouses, Concubines, and Adult landless Children can drastically affect the score.
