Crusader Kings III Best Legacies and Dynasty Perks to Unlock First

Legacies are the closest thing Crusader Kings III has to a skill tree for your whole family. Drop Renown on one and every living cousin, knight, and newborn in the dynasty gets the bonus forever. The catch is that Renown trickles in slowly, the price of every unlock keeps climbing, and buying the wrong tree first sets you back decades. So the order matters way more than most players expect. Here's how the numbers actually work, what the big trees give you tier by tier, and where the community has landed on the best opening buys.

How Renown and Prestige Fuel Legacies

Two currencies, two jobs

People mix these up constantly. Prestige is personal. It belongs to one character, it pays for wars and decisions, and when that character dies it's gone. Renown belongs to the dynasty. It pools up across generations and only the Dynasty Head gets to spend it. You can be swimming in Prestige and still be broke on Renown, and that's normal - a famous king and a famous family are two different things.

There is a kickback the other way, though. Landed family members feed Prestige up to their House Head and the Dynasty Head every month, on top of the Renown they generate. The Dynasty Head's share caps out at +3 a month, and a House Head's at +5. Nice side income, not the main event.

Where Renown actually comes from

Every living dynasty member contributes, and the rate scales hard with title rank:

| Title rank | Renown per month | |---|---| | Unlanded | +0.02 | | Barony | +0.12 | | County | +0.25 | | Duchy | +0.5 | | Kingdom | +1 | | Empire | +2 |

One emperor is worth roughly a hundred unlanded cousins. That's the whole economy in one table.

Marriage counts too. A dynasty member married to a ruler from another family brings in 80% of whatever that ruler's primary title generates - so an empress married into your line pays +1.6 a month, and a foreign queen married to your son pays +0.8. Marrying family up and out is a real income stream, not just an alliance tool.

Two caps keep it honest. Unlanded members stop counting past 100 of them, hard capped at +2 a month from non-rulers total. So flooding the world with babies doesn't grow the pool. Rank does.

And here's the rule that trips up even experienced players: a landed ruler adds nothing if their liege is from the same dynasty. Your son holding a county under you? Zero Renown. Your nephew ruling a duchy under some foreign king? +0.5 a month, every month. Landing family inside your own kingdom is great for control and opinion, but it doesn't grow the dynasty pool one bit. The Renown game is played on other people's thrones.

Level of Splendor

Every point of Renown your dynasty has ever earned also counts toward Level of Splendor, and that ladder costs you nothing. You don't spend on it, it just tracks lifetime earnings.

| Level | Renown needed | Marriage prestige | Alliance acceptance | |---|---|---|---| | Base Origins | 0 | -100 | -5 | | Obscure | 300 | 0 | 0 | | Noteworthy | 2000 | +200 | +10 | | Well-known | 7000 | +400 | +20 | | Famous | 16000 | +600 | +30 | | Glorious | 22000 | +700 | +35 | | Legendary | 37000 | +900 | +45 |

Higher tiers also raise birth prestige, birth legitimacy, the maximum long-reign opinion bonus, and how good the congenital traits on random court guests can get. Reputable (4000) is where guests start arriving with Masterwork-grade traits, and Famous (16000) bumps that ceiling up to Famed.

Splendor almost never goes down. The single way to lose it is a player character attempting suicide, which should tell you how permanent the thing is. That makes early Renown earning a compounding investment - a dynasty that hits Glorious by 1100 enjoys easier marriages for every generation that follows.

What a legacy costs

The first unlock runs 250 Renown. Every one after that costs 500 more than the last, and here's the part most people miss: the count is dynasty-wide, not per track. Your fifth unlock costs 2250 whether it's the fifth tier of Blood or the first tier of five different trees.

| Unlock number | Cost | |---|---| | 1 | 250 | | 2 | 750 | | 3 | 1250 | | 4 | 1750 | | 5 | 2250 | | 10 | 4750 | | 15 | 7250 |

A full five-legacy track from a standing start is 6250 Renown. Your first two game-changing unlocks together cost 1000. That gap is why the opening picks get argued about so much - they're cheap, and everything after them starts to hurt.

Renown also pays for the Dynasty Head's buttons, and those compete with legacies for the same pool. It's 75 to call a dynasty member to war, 150 to press a claim on a relative's title, and 75 to force two warring family branches into a white peace. Disinheriting runs 75 Renown and 150 Prestige for an unlanded kid, climbing to 225 and 900 for someone already landed. Budget for those tools before you commit every point to a tree, or you'll end up with a genetically superior dynasty you can't control.

Blood Legacy Tree Priorities

Look at what players actually recommend and Blood wins the opening more than any other tree. The whole track is about congenital traits - the hereditary stuff like Intelligent, Beautiful, and Herculean, plus their ugly counterparts - and it's the only legacy that compounds forever. A better trait on your heir makes the next heir better, and none of it evaporates when a character dies.

Tier by tier

| Tier | Effect | Cost | |---|---|---| | 1 | +30% chance to inherit positive traits, +30% chance of new good congenital traits | 250 | | 2 | +30% chance to reinforce congenital traits | 750 | | 3 | -30% chance to inherit negative traits, -30% chance of new bad ones | 1250 | | 4 | Pick one trait to make more common among dynasty children | 1750 | | 5 | +5 years life expectancy, slower visible aging | 2250 |

Reinforcing deserves a quick explainer, since it's the quiet workhorse of the tree. When both parents share a trait, there's a chance the child gets the upgraded version instead - Quick becomes Intelligent, Intelligent becomes Genius. Tier 2 raises that chance by 30%, so if you're pairing off relatives who all carry Quick, the family brain trust levels up way faster than the game normally allows.

Tier 5 is the long-game payoff. Five extra years of life on every character you'll ever play, forever. That's five more years of a good ruler, five more years before succession chaos hits, and it stacks with the health stacking available through the Learning lifestyle. Characters built that way routinely make it into their 80s.

Picking a trait in Architected Ancestry

Tier 4, called Architected Ancestry, lets you flag one trait to appear more often in dynasty births. It's a 5% chance at birth, doubled to 10% whenever the player character is one of the parents. The list is fixed: Comely, Quick, Hale, Fecund, Albino, Giant, Dwarf, or Scaly.

Quick is the boring, correct pick most of the time - more skill points on every future ruler is never wasted. Hale (health) and Fecund (fertility) are the practical alternatives depending on whether your problem is rulers dying early or heirs not existing. Giant and Dwarf are genuinely fun and come with real stat swings in both directions. Albino and Scaly are meme territory, though Scaly at least pairs with a certain kind of roleplay.

One quirk worth knowing: if an AI character happens to be Dynasty Head when this unlocks, the game picks a trait at random. Don't leave that decision to a computer.

When Blood is a skip

Short achievement runs don't recoup the investment - you need a century or more for the trait math to pay out. Same if you're playing a dynasty that already starts stacked, like a 1066 Byzantine or Abbasid start where the bloodline's already carrying good genes. But for a long campaign where you care who your rulers are, Blood is close to mandatory, and almost everyone takes at least the first two tiers.

Blade Legacy Tree for Warrior Dynasties

Quick naming note before anything else: there's no tree called Blade in the game. The martial track is named Warfare, and that's what this covers. Same idea though - the tree you grab when your family fights for a living.

What each tier gives

| Tier | Effect | |---|---| | 1 | +2 Prowess, +15% Knight Effectiveness | | 2 | +15% Pursuit Efficiency, -15% Retreat Losses, -20% Casus Belli Cost | | 3 | +10% Martial lifestyle experience, +50% chance to gain Prowess as a knight, -25% chance to die in battle, -25% chance to get wounded | | 4 | +15% Men-at-Arms Counter Efficiency, +5 Advantage | | 5 | +1 Men-at-Arms regiment limit, unlocks House Guard men-at-arms |

Tier 4 is the spike. Advantage is a flat edge in the battle math, and +5 applies to every fight your family's armies get into. Stack it with the +15% counter efficiency and your men-at-arms start winning matchups they had no business winning.

Tier 2's casus belli discount is sneaky good for a warlike start, since declaring wars costs prestige and gold scaled to the size of the war. Cheaper wars means more of them.

Tier 3 is the dynasty bodyguard package. Your relatives stop dying in battle at a 25% lower rate and pick up Prowess faster while knighted. If you're the sort of player who makes the heir a knight, knock it off, but the AI does it constantly with family members - and this keeps your spare princes breathing.

House Guard

Tier 5 hands you an extra men-at-arms regiment slot plus House Guard, a heavy infantry unit that's flatly better than the standard version. Community consensus puts it above most culture-specific heavy infantry too, with the catch that you only get one regiment of them. One free elite regiment for every dynasty member who can field men-at-arms adds up fast.

Who should actually take it

This is the tree for 867 tribal starts, Norse adventurers, the Iberian struggle, or any campaign where the first century is one war after another. A tall, peaceful, diplomatic run gets much less out of it - you'd be paying for muscles you never flex. And remember the bonuses hit every dynasty member, not just your ruler. Your martial cousins and your household knights all get stronger even while your ruler is off reading manuscripts.

Chivalry and Splendor Legacy Trees

Glory is the closest thing CK3 has to a chivalry track - knights, marriages, grandeur, being the family everyone wants to be related to. Splendor is the other half of the equation, the fame ladder your lifetime Renown funds for free. Together they make the beloved-household package.

The Glory tree, tier by tier

| Tier | Effect | |---|---| | 1 | +30 Marriage Acceptance, +5 Glory Hound opinion | | 2 | +10% monthly Prestige, +1 knight, -10% mercenary hire cost, +100% court grandeur change, +1 Accolade | | 3 | +10% Diplomacy lifestyle experience, -20 days personal scheme phase length | | 4 | +10 vassal limit, -20% short reign duration, +5 court grandeur, -20 claimant and liberty faction acceptance for your vassals | | 5 | +10 general opinion, +1 max sway scheme |

Tier 1 at 250 Renown is one of the best cheap buys in the game. Thirty points of marriage acceptance makes good matches and clutch alliances dramatically easier to land, and it applies to every marriage any dynasty member arranges. For a 250-point unlock that's absurd value.

Tier 4 is the payoff for anyone running a big empire. Ten more direct vassals before you're forced to hand out duchies or eat the opinion penalty for leaving powerful people off the council. A shorter short-reign penalty after every succession. And your vassals being 20 points less willing to sign onto claimant and liberty factions, which quietly deletes half the civil wars you'd otherwise fight.

How Splendor plugs in

Glory makes your family popular. Splendor makes it famous, and famous is what lets the marriage bonuses actually land against other great dynasties. The two feed each other - Splendor tiers make marriages easier with lower-standing families, and Glory's opening tier pushes acceptance up across the board. A Glorious-tier dynasty running Glory tier 1 can marry into almost anyone's line, and that means better alliances, better congenital traits coming in, and more Renown flowing back through those marriages.

The Activities tree as a companion

If chivalric roleplay is the actual goal, Activities is the companion track worth a look. Half-cost grand weddings with +15 acceptance at tier 1, faster Pilgrim and Traveler trait experience, tour bonuses, and quicker Hastiluder and Hunter gains for the tournament and hunt characters. Grand weddings also generate Renown, which feeds everything above. It's a softer tree than Glory, but for a court that lives for feasts and jousts it fits the fantasy exactly.

Long-Term Dynasty Planning Across Generations

A standard opening order

The community default, more or less settled after years of arguing:

1. Blood tier 1 (250)
2. Blood tier 2 (750)
3. Blood tier 3, or branch to Warfare or Glory tier 1 if you're at war constantly
4. Kin tiers 1 and 2
5. Then finish Blood, or push deep into Warfare or Glory based on how your campaign is shaped

Kin earns its spot in almost every recommended order. Tier 1 is +10% fertility and +5 attraction opinion, which directly attacks the "no heir" problem that ends more runs than any war. Tier 2 gives +10 child opinion and a +2-3 education score bump for every kid in the dynasty, which is basically free lifestyle levels on your next three rulers. And tier 5 stops Prowess decaying with age while handing out +1 random skill point at 30 and every five years after. For a family that's already smart and healthy from Blood, those late Kin tiers turn 60-year-old rulers into monsters.

Placing family on thrones

Go back to the liege rule from earlier, because it's the whole strategy. Landed relatives under your own crown add nothing. Independent ones, and ones sitting under foreign lieges, add plenty. So the long game is seeding your family across the map - a cousin on a neighboring kingdom's throne is +1 a month, an emperor wearing your name is +2 a month, and a dynasty member married to a foreign ruler kicks back 80% of their title's rate.

A hundred unlanded cousins cap at +2 a month combined. The pool grows with rank, not bodies. Every throne you put family on makes every future legacy cheaper.

Keeping the Dynasty Head seat

The Dynasty Head is usually the strongest House Head by military strength, and another house head who gets 10% stronger takes the seat right off you. This matters more than it sounds, because an AI Dynasty Head only spends Renown on whichever track already has the most progress. Your carefully balanced two-tree plan stalls the moment a powerful cousin branch wins the internal arms race. Keeping the head slot means keeping the biggest army in the family, which is a quiet argument for the Warfare tree that nobody mentions.

The snowball, in rough numbers

A small 867 dynasty might pull 0.3 Renown a month early on. At that rate the first two unlocks (1000 Renown together) take decades, and that's normal - the early game is for surviving and placing family, not buying perks. Fast forward to 1100 with relatives on four thrones and a climbing Splendor score and you can be earning 5 to 8 a month, which buys a new tier every few years without thinking about it.

That curve is the real reward for patience. The cheap unlocks come when you're poor and the expensive ones come when you're rich, provided you spent the early centuries getting family onto other people's thrones instead of stacking them under your own. The number to watch is the monthly Renown figure on the dynasty screen. When it's climbing, everything downstream gets easier. When it's flat, no amount of saving digs you out - go marry a cousin into a kingdom and check back in twenty years.
