Renown is the resource that turns a single-character playthrough into a multi-generation one in Crusader Kings III. It is dynasty-level Prestige: every dynasty member contributes, the dynasty head controls the spending, and the spend unlocks Dynasty Legacies that benefit every living member. The trap new players fall into is treating renown like personal Prestige and spending it on early Dynasty Head actions instead of feeding Legacy tracks. This guide maps the official mechanics from the base game and the Royal Court expansion (which added the Customs legacy) onto a realistic build order.

What changed: how renown works in the current build

Renown is earned by the dynasty as a whole. The three official sources are the number of currently living dynasty members, the number of dynasty members who are spouses of rulers, and the number of rulers who are not vassals of another dynasty member. Independent crown-wearing relatives therefore matter more than court size, which is why large splits of the dynasty across independent kingdoms produce the fastest renown gains.

The dynasty has a Splendor level that rises as lifetime renown accumulates. Splendor starts at Base Origins and can climb through ten further tiers (Obscure, Insignificant, Noteworthy, Reputable, Well-known, Significant, Famous, Glorious, Fabled, and Legendary). Each tier gives small but compounding bonuses: dynasty children are born with more Prestige, marriages into the dynasty are worth more Prestige, and the dynasty gets a higher maximum opinion bonus from long reigns. The Splendor level is not the same as current renown: renown is a balance you spend; Splendor is a record of how much you have ever accumulated, and it does not go down when you spend (it only decreases if a player character attempts suicide).

The dynasty head has exclusive decisions paid in renown (the cost varies by target): Claim Title (150 renown), End Dynasty War (75), Denounce (125 renown plus 500 Prestige), and Disinherit (which scales with target rank, up to 225 renown plus 900 Prestige for Landed members). Cadet branches can also form when a ruler is Feudal or Clan, is not third in line or closer to any title held by the house head, has no living ancestors in the current house, and (for women) is in a matrilineal marriage, at no cost but with a +350 Prestige gain. These are the spend-paths that compete with Legacy tracks, and the right ratio depends on which Legacy you are racing.

How it works: the Legacy tracks

The base game ships with seven core Legacy tracks, and post-launch updates and expansions have added more: the Royal Court expansion added Customs, the Northern Lords flavor pack added Adventure and Pillage for North Germanic dynasties, the Royal Court and later content added Activities, Heroic Bloodline, and Legitimacy, and additional culture- or government-specific tracks (Metropolitan, Coterie, Brilliance, Bureaucracy, Nomadic, Virtues, Divine Aspirations, Elegance) unlock for dynasties that meet the relevant heritage or government conditions. Each track has five tiers, and tier costs follow the structure introduced in patch 1.3 “Corvus”: the first legacy on a track costs 250, the second 750, then 1,250, 1,750, and 2,250 for tier 5. That is 6,250 renown to complete one track, and 17,250 to clear the first two branches of a second one. Patch 1.3 also rebalanced every track (their effects should be more tangible than at launch), so the first three tiers remain the most cost-efficient relative to their contribution.

The tracks and the standout tier-1 / tier-5 effects, drawn from the in-game tooltips:

  • Warfare. +2 Prowess at tier 1; +1 max Men-at-Arms regiment and access to a House Guard regiment at tier 5. Good if your dynasty is small and you want every member to fight.
  • Law. +5 Popular Opinion at tier 1; +1 Domain Limit at tier 5. Steady realm-management track, especially for tall rulers.
  • Guile. +20% Dread gain at tier 1; one-time save against a murder attempt against each dynasty member at tier 5. A pure Intrigue track.
  • Blood. +30% chance to inherit and gain good congenital traits at tier 1, +5 years of life expectancy at tier 5. Slow, but compounds across generations.
  • Erudition. +10 Courtier and Guest Opinion at tier 1; +10% progress and skill impact on councilor tasks at tier 5. Pairs with tall Learning rulers and Royal Court court positions.
  • Glory. +30 Marriage Acceptance at tier 1; +10 General Opinion at tier 5. The diplomatic and marriage track.
  • Kin. +10% Fertility at tier 1; no Prowess loss from age and skill gains with age at tier 5. The “long campaign” track, where every decade of ruler time matters.
  • Customs (Royal Court). Added with the Royal Court expansion. Across its tiers the track adds a foreign language limit and faster Learn Language schemes, an extra Learn Language scheme slot, +20% Cultural Acceptance Gain, and unlocks the Cultural Emissary court position. The “multicultural empire” track.

Each track has niche prerequisites, and several of the tier-1 effects are already accessible through other means (popular opinion from buildings, dread gain from certain traits, marriage acceptance from high Diplomacy). The unique value is usually the tier-4 and tier-5 payoff, which is much harder to get elsewhere.

Build path: which Legacy to commit to

The right first track depends on what your dynasty is doing right now.

  • Small dynasty, high centralization: Warfare or Guile. If you have a tight realm with one or two strong rulers, the Prowess and Men-at-Arms cap from Warfare gives every dynasty member a noticeable bump, and Guile’s anti-murder save at tier 5 protects the bloodline in succession-heavy games.
  • Large dynasty, scattered independent realms: Kin or Blood. Kin’s +10% fertility at tier 1 alone can pay for the rest of the track by inflating dynasty head count, and the tier-5 anti-age effect stops your best knight from losing Prowess at 60. Blood is the slower play: the congenital-trait stacking at tier 1 through 4 is one of the only ways to get Comely, Quick, Hale, or Fecund reliably in your line (the tier-4 “Architected Ancestry” lets you pick one trait to make more common), but you have to live through several generations to see the payoff.
  • Court-heavy, tall rulers: Erudition. +10% councilor skill impact and +10% progress on their tasks at tier 5 is a serious realm-management buff, and the Royal Court court positions turn the tier-1 +10 Courtier and Guest Opinion bonus into a real power source for Artifact Inspiration.
  • Multicultural empire (Royal Court): Customs. The acceptance bonus on Learn Language completion, plus the extra Learn Language scheme slot, are the key enablers for the hybridisation and divergence loop Paradox described in the Royal Court expansion. If you plan to absorb multiple cultures into one, Customs is the foundation.
  • Marriage and diplomacy game: Glory. +30 marriage acceptance is the headline, but the tier-5 +10 general opinion is what makes new vassals stop joining factions.

A common, defensible order is to finish one full track (6,250 renown) before even starting a second, unless a specific tier-1 of another track solves an immediate problem. The 1.3 cost structure makes five tier-1 legacies slightly more expensive than one full track, but the spread buys mid-game strength without locking the dynasty into a single identity.

Renown farming: what actually moves the number

Three levers reliably increase the monthly renown tick:

  1. More living dynasty members. Marriages that produce children, plus saving dynasty members from dying (your Spymaster’s “Protect” task and your court physician’s “Treat Disease” task both help). Each member of the dynasty, alive and titled or not, contributes.
  2. Dynasty members married to rulers outside the dynasty. A daughter married matrilineally to a foreign king is the most common source. The match is a one-time hook but the children pull the new king’s bloodline into yours if the marriage is matrilineal.
  3. Independent dynasty rulers. This is the big one. A single independent king of your dynasty pays out more renown than a dozen counts serving as vassals. The Claim Title dynasty head interaction (150 renown) can put a dynasty member on the warpath for one of your dynasty’s titles, which over time produces more independent crowned heirs.

Hybridisation itself generates renown through the Cultural Acceptance gain, which is why Culture Blending (-75% Hybrid Culture Creation Cost, +25% Cultural Acceptance Gain) and the Customs Legacy work in the same direction.

What does not help: personally holding more land. The number of counties you personally hold is a Piety and Gold question, not a Renown one. The renown button measures dynasty spread, not personal power.

What it means: a practical three-generation plan

If you want a defensible plan on a fresh run:

  • Generation 1. Focus on marriage and dynastic spread. Matrilineally marry daughters into nearby kingdoms. Avoid burning renown on Disinherit or Claim Title unless succession demands it. Start Erudition or Warfare, whichever fits your ruler.
  • Generation 2. By now you should have at least one independent dynasty ruler outside your realm. Continue marrying, and start the second Legacy track (often Kin, since more children from the +10% fertility tier-1 is the cheapest accelerator). Hold off on Cadet Branch unless you specifically want a new house head for the second track.
  • Generation 3. With Splendor at Reputable or higher, decide whether to commit to a tall third track (Blood for the congenital stacking) or pivot to the realm-management track (Law or Erudition capped at tier 5).

This is not the only valid order, but it reflects the underlying constraint: renown is a slow currency, and any plan that assumes you will finish two full tracks and a half-track in a single ruler’s lifetime is wrong for the numbers Paradox published.
