There are three important resources which are necessary for most actions in the game: Prestige, Piety and Gold. Each resource can be spent on different things and all of them can be spent or gained through events.
Prestige represents a character's social standing. It is gained primarily by holding titles. Prestige can be spent on vassal interactions, decisions and declarations of war. Prestige has one "weaker" currency, fame.
Level of fame
A character's level of fame measures their general reputation and how well perceived they are by everyone. Fame is a resource that accrues but cannot be spent in the way that prestige can. However, each time a character gains prestige, they will also get an equivalent amount of fame. As fame accrues, it will increase progress towards their next level of fame, which grants various benefits. Prestige lost from doing dishonorable actions will lower a character's level of fame. A character can pay a prestige cost by paying levels of fame if it doesn't have enough prestige.
Piety is a measure of how virtuous a character is in the eye of others and is gained primarily from religious relations and the character's Learning skill and traits that its Faith considers virtues. Piety is spent when interacting with the church and declaring holy wars. The icon displayed for representing piety depends on the character's religion.

Level of devotion
Each time a character gains piety, they will also gain devotion, which gives progress towards their next level of devotion. Like the levels of fame above, each level of devotion grants various benefits. A character will lose a level of devotion if they are caught doing something their faith doctrines consider shunned. A character can pay a piety cost with devotion if they don't have enough piety. Generated characters and those at the game start begin with the Dutiful level.
Gold is a measure of a character's wealth reserves. Most rulers start the game with Gold equal to 12 months of income.
Debt occurs when a character has negative Gold. During Debt characters cannot declare war, their Counties can always acquire Corruption, their Men-at-Arms cannot reinforce and they can experience various negative events. In addition Debt grants increasingly negative modifiers the longer it goes on.
|Years in Debt||Levy Size||Levy Reinforcement Rate||Development Growth||Vassal Opinion||County Opinion||Advantage||Join Faction Acceptance|
Monthly gold income comes from multiple sources.
Domain tax is generated by a character's personal holdings. The holder of the barony receives all of the barony's domain tax. It can be increased by the following:
- Character's Stewardship skill (+2% per level)
- Collect Taxes council task (+0.5% per Stewardship level)
- County development (+0.5% per level)
Vassal tax is given to a title holder's direct liege. The amount given depends on the vassal's obligations:
- Castles are limited to normal obligations, giving 10% of their domain tax to the liege.
- Cities are held by republics, who provide 20% taxes.
- Vassal counts, dukes and kings provide tax based on their individual vassal contracts.
- With the Lay Clergy doctrine, churches function identically to castles.
- With the Theocratic doctrine, churches are held directly by a Realm Priest and are taxed under the system explained below.
Realm Priests receive vassal income at a rate of 25% from Realm Priests belonging to their liege's direct vassals. They also provide up to 50% of their income from directly-controlled churches and their vassal priests to their feudal liege, scaled based on opinion.
The taxable income of feudal vassals (count/duke/king) is their own domain tax, as well as vassal tax from their own vassals. If the vassal receives income from a Realm Priest, this income is not included as taxable income.
- Renown, a resource related to dynasties.
