Short version: there is no button that turns your current ruler into a Conqueror. CK3 runs a check every five years, and you pass or fail it on a short requirement list plus a weighted roll you can stack in your favour. The one route you can force is to play landless and take the Become a Great Conqueror decision.
The Conqueror trait arrived with the Roads to Power update and it is, without much argument, the strongest thing a ruler can have in this game. It turns a quiet duchy into the reason half the map stops being static. It is also the most misunderstood trait in CK3: plenty of players have conquerors spawn in their campaigns without ever realising there is a system behind it, let alone that you can nudge it.
Here is how it actually works: what the trait gives you, the requirements, the numbers behind the roll, how inheritance works, and how to get it on purpose if you are tired of waiting for the dice.
What the Conqueror trait actually gives you
Before you chase it, know what you are chasing. These are the trait's flat modifiers, one per row, as listed in the game's own data:
| Modifier | Effect |
|---|---|
| Monthly tax | +5 gold |
| Monthly legitimacy | +5 |
| Men-at-arms maintenance | −75% |
| Title creation cost | −75% |
| Casus belli cost | Free, no prestige or piety |
| Force vassalisation | Casus belli unlocked |
| Factions against you | Cannot form |
| Enemy hostile scheme phase length | +25 days |
| Enemy hostile scheme growth | −3% |
| Enemy hostile scheme potential | −40% |
Rewards that arrive on a timer
- Every year: a claimant joins your court, which is a casus belli waiting to happen.
- Every 3 to 6 months: a free building in your capital, men-at-arms grow by one regiment, and +2 to a random skill.
- Every 3 to 6 months, gated: prestige, gold, stress loss, and a 15% chance of an education trait level. The game's own list puts these on the trait, but the community reading is that this half applies to AI conquerors, and to any ruler carrying the Scourge of the Gods modifier.
Read the men-at-arms line again. Maintenance cut by three quarters means the usual reason to stop fighting (the army costs more than the realm earns) stops applying. Add a free force vassalisation war against anyone and the trait stops being a bonus and becomes a different game.
It changes how the AI plays, too. A Conqueror ruler pours every coin into the war chest and men-at-arms, forgives activities and inspirations, and spends prestige on going to war and nothing else. Which is exactly why a conqueror realm blobs across the map like a player would do it, and then takes everything it can before the trait moves on.
The check: every five years, two steps
By default the game runs a check on a five-year pulse. It has two stages, and the first one is binary.
Step one, who is even in the pool. The game filters characters against a requirement list. Fail any item and nothing else happens this cycle; pass and you go into the draw. This is why the trait sometimes never appears in a long campaign: the pool is small, not the dice unlucky.
Step two, the roll. Everyone who passed gets a chance, weighted by a long list of modifiers. The base chance is 0.25%, and simply being a player character subtracts 2.5 percentage points from it before any bonuses. Yes, the game is less willing to hand it to you than to an AI. With the right ruler in the right realm you can still climb well past that, and over several pulses it is the difference between "never in 200 years" and "sometime this decade".
So the useful question is not "when do I get it". It is "am I even eligible, and how much weight am I stacking".
The requirement checklist
For randomly becoming a Conqueror, the character has to satisfy all of this:
- Not Incapable
- An adult, and at most 60 years old
- Has at least 50 gold
- Is an independent, landed ruler, duke tier at least
- Has at least 3 domain
- Has no allies
- Is not at war when the check fires
- Does not hold the Mongol Empire title
- Has not already been a Conqueror
- Has a valid casus belli against any neighbour (or one close enough by sea) and a stronger army than them
- Is in a world with fewer than 12 Conquerors already. The conditions waive that cap for the player when the "no special bonuses to conquerors" rule is active, which is the one line of the list everybody reads backwards
Set the frequency rule to "strong rulers only" and the pool narrows further: those rulers also need 4 domain, 15 realm size, 3,000 soldiers, 500 gold and an age of 35 or under.
Three items catch people out. You can be a king with 40,000 soldiers and still be skipped, because holding the Mongol Empire title removes eligibility outright. That is the title, not emperor tier as such, so an emperor without it is fine. Being at war when the check fires drops you out for that cycle. And the ally clause is the quiet one: a marriage alliance you took for safety disqualifies you until it ends, which is why conquerors and alliances rarely last in the same realm.
The age limit is the cruellest part. The trait exists to inject a mid-game storm, so it looks for rulers with decades ahead of them, and stops looking at 60.
What raises your chance
Once you are in the pool, these are the weights. The numbers are the additive weights as dumped from the game's script in the Steam discussions (a 1.13-era dump), so read them as percentage points added to that 0.25% base rather than as a promise about the current patch:
| Weight | Approximate effect |
|---|---|
| Your primary title tier | + (tier ÷ 12). Small on its own: it is the stepping stone to the kingdom bonus below, not a lever by itself |
| Temporal head of faith, or the temporal head is your vassal | +5. The single biggest weight in the list |
| Kingdom tier, with conquest casus belli, fame above Distinguished and 12 months of income banked | +4, and it stacks with everything else |
| Conquest casus belli available (unreformed faith, Warmonger or Pursuit of Power tenet, tribal or clan) | +2, or −0.5 if you cannot use one at all |
| Tribal or clan government | +1.5 |
| Exalted Warlord (martial education 5) | +1 |
| Martial above 10 | + (martial ÷ 5), so 20 martial is +4 |
| Intrigue or diplomacy above 10 | + (stat ÷ 10) each |
| Ambitious / Brave | +0.5 / +0.25 |
| 18 months of income in the treasury (for nomads, a full war chest counts) | Bonus, no figure published |
| Bellicose ethos on your culture | +0.25 |
| Illustrious fame rank or higher | +0.25 |
| Warmonger tenet in your faith | +0.25, while a Pacifist tenet is −0.25 |
| Child of Destiny, Tool of Fate, or the foreign-raised reformed story chain modifiers | ×5 multiplier. These are the modifiers that make a character the protagonist |
| Being a player character | −2.5. The largest penalty in the list |
| Content / Craven | −1 each |
| Compassionate, Shy, Lazy, or a culture geared towards converting to a pacifist faith | −0.25 each |
| Princely Elective as your succession title | −0.25 |
The practical read: a young tribal duke with high martial, a Bellicose culture, an unreformed faith with Warmonger, a conquest casus belli and cash in the bank is close to the shape the system is hunting for. Add the temporal headship of your own faith and half the job is done. What kills a candidate is the opposite of all that: an organised faith, no conquest casus belli, no money banked, Content and Craven in the family, or simply being 61. If you are arriving here from my CK2 tribal guide, it is the same instinct that paid off there (cheap prestige armies, no reason to stop expanding), except this time the game hands you the whole thing.
One honest caveat about those numbers: they were published for the version that introduced the trait, and no weight figures have been posted for later patches. What the patch notes do say is that the player's odds came down. In 1.16, players were rebalanced to be "much less likely to randomly become a Conqueror". Treat this as a system to lean on, not a plan to count on.
The one route you can force: landless adventurer
If you want the trait on purpose instead of by luck, do not build a duke and wait. Play landless with Roads to Power and take the decision Become a Great Conqueror. It needs the Conquerors frequency rule not to be set to None, and at least 8 of the following:
- 22 Martial, or 28 Martial
- Living Legend fame rank
- 20 wars fought, including 5 against kings or emperors
- 4,000 men-at-arms
- 12 characters killed
- 20 completed Stand With Me or Raid for Captives contracts
- Both the Strategist and Gallant traits
- Two commander traits
- Six knights at 18 prowess, or twelve at 12 prowess
Take the decision and, once you are landed, the trait fires. You get a pressed claim on the top non-emperor title where your camp sits, a 700-man retinue army that is not inheritable, and a war against the current title holder to press that claim. This is the RNG-free version: eight of those conditions are ordinary mercenary work, and you can measure your own progress towards them instead of waiting on a five-year pulse.
Inheritance: keeping it, and stopping it
By default the trait passes to your primary heir, and eligibility matters:
- The heir must be an adult, and either independent or about to be
- They cannot be Craven or Content, and cannot have a cautious AI personality
- Under elective or acclamation succession, whoever wins the election inherits, not necessarily your nominated heir
- With multiple titles of equal rank, the primary-title heir is the one who keeps it
That last pair is why you sometimes see a Conqueror dynasty end for no obvious reason: the wrong brother won the election, or the primary title went to a child. If you want the trait to continue, control the succession before you die. If you are on the receiving end of a monster neighbour, an elective title is a quiet way to break the line.
Two game rules change all of this, both worth setting before you start: the Conqueror frequency rule (none, reduced, increased, each also available as "strong rulers only") and the inheritance rule (All Heirs, Primary Heir by default, or No Inheritance). Playing with no inheritance gives you one great storm rather than a family of them, and none of these rules disables achievements.
Console commands, and the mistake everyone makes
Yes, you can add it directly: add_trait conqueror. But a trait added this way is not inherited by your heir, however qualified they are, because it never ran through the event that grants it. If you want a dynasty of conquerors rather than one ruler, use event conqueror.0001 instead. (Community-reported, not documented, so test it before you build a run around it.)
Frequently asked questions
Can I start the game as a Conqueror?
Not normally. The exception is Temujin, who has a scripted conqueror event in the 1178 start and in Khans of the Steppe, tuned to fire while he is roughly 30 to 40.
Does every ruler become eligible eventually?
No. Holding the Mongol Empire title rules you out permanently, anyone past 60 is out, and being at war or allied on the day of the check means sitting out that cycle. Being eligible is a state you can lose.
What is Scourge of the Gods?
An optional modifier conquerors can receive under the game rules: bigger health, army and scheme bonuses, close to what Genghis Khan brings. According to the community reading, the player's first Conqueror does not receive it but heirs can, while AI conquerors can start with it.
Is a Conqueror neighbour a threat or an opportunity?
Both. Their realm is stable, their armies cheap, their factions suppressed, and their casus belli are free, so they will use them. They also make untrustworthy allies and are usually at war with someone.
Can I turn the whole system off?
Yes. The Conqueror frequency rule can be set to none or reduced. If you disable Conquerors entirely, note that the landless Become a Great Conqueror decision requires the rule not to be None.
Sources and version
The requirement and weight lists come from the conqueror conditions published by the CK3 team and reproduced in the community, and the numeric weights and modifier list from the game's script as dumped in the Steam discussions in October 2024 (the 1.13 Roads to Power era). The Great Conqueror decision comes from the CK3 wiki's Adventurer decisions page, which lists its full cost and requirement set. Some details (heir eligibility, the player's first-ruler carve-out on Scourge of the Gods, the console command behaviour) are community-observed rather than officially documented, and are marked as such above.
Version: the trait arrived with Roads to Power / 1.13. Patch 1.16 "Chamfron" (April 2025) rebalanced the player's random chance downwards and reworked Temujin's event. The game is currently on 1.19 "Scribe" (April 2026, bugfixes through 1.19.0.6). The CK3 wiki's Conqueror page is the canonical reference for the conditions, and the patch notes are worth checking if a newer patch has moved these numbers again.
