Introducing CK3 #08 - Technology. Havoc will introduce you to Technology and how you can unlock more of them!
Innovations represent technological, legal and ideological advances that a Culture can make. Once an innovation is unlocked, it can be used by any County and Character of the culture which unlocked it. Innovations are grouped into 3 categories: Military and Civic, Cultural, and Regional.
Military and Civic innovations have a small chance to progress towards being unlocked each month based on multiple factors, the most important being average Development in Counties of the Culture. The second most important factor is the number of neighbor Counties that belong to another Culture which already unlocked an innovation (Exposure).
Regional innovations are unlocked when the Culture has a sufficient presence in a certain Region, and remain unlocked even if said territory is lost.
Cultural innovations are always active, but require a certain Culture.
Feudal and Clan Governments rely on Innovations to unlock higher Crown Authority and De Jure claim Casus belli.
The advancement chance is 5% + Fascination % + 40% there is exposure.
Exposure is gained when another culture within the same religion already has the Innovation.
Fascination is 20% as a base, plus 2% per the Culture Head's Learning skill.
With the Scientific perk, these numbers go up to 27% base and 2.7% per the Culture Head's Learning skill.
Amount of advancement gained = 0.3 + (average cultural province Development * 0.02) + 0.2 if ahead in era.
Random Innovations by decisions like "Unite the Slavs" are decided by the in-game date.
Each Culture will be within one of 4 Eras which determine which innovations the Culture can unlock.
Once at least 50% of the innovations of an Era are unlocked and the required minimum year is reached, the Culture will slowly progress to the next Era based on the average Development in the Culture's Counties.
A culture cannot progress to another Era if its Cultural Head is Tribal.
The Tribal Era of a Culture predates the emergence of codified laws and an institutionalized government. Rulers with Tribal Government can only make use of Tribal Era innovations.
The Early Medieval Era sees the emergence of professional administrators and a number of important innovations, allowing a Culture to exit the Dark Ages.
The High Medieval Era is a time of great technological and administrative progress, seeing towns grow into cities and the rise of the burgher class even as the aristocracy reigns supreme.
The Late Medieval Era marks the zenith of the feudal world. Bureaucrats, artisans, merchants and money lenders are starting to encroach on the power of the old privileged classes, except for the monarchs themselves.
Might makes right has been the law of the land for generations, but if we have a justification for our wars then we can avoid provoking the ire of our neighbors and the retaliation that often comes with it.

By designing our cities before we start constructing them, we can create new holdings in strategic locations which are both more functional and aesthetically pleasing than the older ones which haphazardly arose over time.
Unlocks all Tribal Era Economic Buildings
By transitioning from the traditional two-field farming model to three-field crop rotation, we can grow more crops each year without depleting the soil on our farms.
+10% Monthly Development Growth
Bartering is slow and inefficient; adopting an officially-recognized currency like cowrie shells or metal nuggets will bolster trade and increase the spread of ideas within our realm.
Can enact the Confederate Partition Law
Stability and prosperity go hand-in-hand. Instead of having vassals jockey for power when the old monarch passes away, we can define a predetermined, equitable system of inheritance which will eliminate much of the instability which traditionally occurs on succession.
+1 Domain Limit
As our lands grow, we need a better way to keep track of what we own. Maintaining a ledger of our possessions will ensure that we always know what resources we have at our disposal.
Unlocks Fortified Tribal Hold Can enact Limited Crown Authority Law
In order to effectively govern, we must bring all free men of the realm together to discuss and resolve legislative matters. Attendance is mandatory, and those who do not come will be fined and forfeit their ability to influence any decision made.
Counties reach the maximum Existing Development penalty at 20 Development
Funding the construction of public works like roads, schools, and aqueducts will allow our settlements to grow to larger sizes, ensuring the prosperity of our people for generations to come.

+2 Size of Men-at-Arms Regiments +1 Max number of Men-at-Arms Regiments
Simply having people willing to fight for us is not enough to win wars. Setting aside space for people to both train and muster for battle will allow us to support groups of more experienced fighters who can lead us to victory.
Can recruit Onager Men-at-Arms
While slow to load and fire, torsion-powered catapults like these allow us to assail enemy fortifications while staying out of their archers' range.
Can recruit Armored Footmen Men-at-Arms
Formed of a dozen or more layers of linen stitched together, these jackets can stop even heavy arrows and are an affordable way for us to armor an entire regiment for battle.
The bush is a rough and rugged place, but it offers a bounty of opportunity for those who know where to look and how to exploit it. Training our archers in these techniques will give them an advantage when engaging enemies in these areas.
Can recruit Chu-ko-nu Archers Men-At-Arms
The repeating crossbow, known as Chu-ko-nu, is an ingenious invention with an easy-to-use mechanism that can be operated by anyone. What it lacks in range and firepower, it more than makes up for in rate of fire, making it an ideal weapon for defensive positions.
Can recruit Horse Archers Men-At-Arms
Crafted from laminated strips of horn, wood, and sinew, our compound bows are much smaller than a traditional bow while being just as powerful. This reduced profile makes it possible to comfortably fire from horseback, allowing us to field truly devastating horse archers in battle.
Can recruit Shomer Men-At-Arms
Our people have been exiled and driven out time and time again. While tragic, these experiences have led us to become exceptionally skilled in rear-guard tactics which minimize casualties.
Can recruit Metsänvartija Men-At-Arms

Table of Princes
Can enact the House Seniority Law and at any Crown Authority
The Table of Princes is the royal seat of Bohemian rulers, with the one sitting at the table being recognized as the rightful ruler. Under the code of house seniority, titles were given to the eldest living member of the ruling dynasty.
All Guinean Uplanders

The hills of the wooded savanna have been our homeland for generations. Our ancestors showed us how to utilize this terrain, and with raiders threatening our borders, we can use this knowledge in our defense.
Can enact the High Partition Law
Can enact the Equal Law and at any Crown Authority
Although many of the older traditions of the Visigoths have long been wiped from the world, the children of the Pyrenees remember the ancient ways, and how land was divided between sons and daughters practically but fairly.
Can recruit Zbrojnosh Men-At-Arms
The forested hills and mountains of our homeland demand a different approach to warfare. Our armed men, the Zbrojnosh, are trained to turn the terrain to their advantage and have proven to be good fighters capable of defeating much larger armies.
Elephants are difficult to raise in captivity, so each mahout must capture their own wild elephants and train them. This means there is a delicate art to properly using these great creatures in battle, but it is an art we are dedicated to mastering.
-75% Embarkation Cost
+25% Naval Speed
Unlocks the ability to sail in Major Rivers
Unlocks the ability to Raid over seas if Raiding is allowed
Our longships are formidable seafaring vessels which can travel almost anywhere and even brave rough weather, giving us exceptional mobility on the seas.
Middle East, North Africa or Persia
Can recruit Camel Riders Men-at-Arms
Camels are naturally suited for living in desert terrain, but they aren't inherently creatures of battle. Our breeders and trainers can change this, giving us access to adaptive cavalry which will let us master the sands.
West African Canoes
-25% Embarkation Cost
+10% Raid Speed
Unlocks the ability to sail in Major Rivers

Comprised of a spherical framework of moving rings, these devices allow us to chart and predict the movement of the heavens. While a fascinating astrological device in its own right, this knowledge will also help aid our captains when navigating waters far from land.
+1 Domain Limit
A king cannot be everywhere at once. By appointing bailiffs to enforce the king's law throughout the realm, we can govern a larger area more effectively than we could otherwise.
Can use De Jure Duchy Casus belli -10% Casus Belli Prestige Cost
No more will the stories of our family's exploits be passed down just through oral tradition. We will keep a record of all that we accomplish, both to inspire future generations as well as to prove our claims over lands we should rightfully hold.
+10% Monthly Development Growth Unlocks the Coinage Rights Feudal Contract
Unregulated currencies are difficult to control and lack stability. Minted coins, measured to specific weights and stamped with a royal seal, give new confidence to commercial transactions.
Counties reach the maximum Existing Development penalty at 35 Development
Larger towns regularly face a series of increasingly complex problems. Delegating some authority to local councils will let them resolve these issues without needing to get the king involved.
Can enact the Partition Law
Evenly dividing the realm amongst all eligible heirs fractures the unity of our people. Instead of tearing our realm asunder on every succession we can ensure we have a stable and prosperous heartland by establishing a system of hereditary rule.
-10% Building Construction Time Unlocks all Early Medieval Era Economic Buildings
With land ownership consolidated under our elite, many men and women find themselves unable to work. We will establish a manor system where free men can work our fields in exchange for rent, while those who cannot pay may enter our service as bound serfs instead.
Can enact High Crown Authority Law Can enact Absolute Crown Authority Law
As our royalty has a greater burden placed upon them by their responsibility to govern the realm, so too shall they be bestowed with privileges reserved exclusively for them.
Light cavalry are a force to be reckoned with, but they do not truly exploit the potential of the warhorse. Arched saddles allow us to field heavily armored warriors with couched lances, which lets them take full advantage of their momentum as they charge into enemy lines.
-5% Men-at-Arms Maintenance Unlocks all Early Medieval Era Fortification Buildings Unlocks the Fortification Rights Feudal Contract
Beyond fortifying just the keep itself, building a durable outer wall which can be safely manned by our archers will give our castles an extra layer of protection against attackers.

+3 Size of Men-at-Arms Regiments +1 Max number of Men-at-Arms Regiments

Can recruit Mangonels Men-at-Arms
A significant improvement to our existing catapult designs, traction-powered mangonels are much faster to load and fire than torsion-powered machines.

All Byzantine except Alan
Can recruit Cataphracts Men-At-Arms

All East Slavic
Can recruit Druzhina Men-At-Arms
Varangian soldiers have long served as imposing bodyguards for our monarchs, but they can just as easily serve as dedicated heavy infantry in our armies.
All North Germanic

Royal Army Tradition

It is time that we recognize that it is divine will that has placed our rulers on their thrones, and to oppose them is to oppose divinity itself.

+5% Monthly Prestige Can enact the High Partition Law Can enact the House Seniority Law
Establishing hereditary designs to identify our noble families will cause their members to see themselves as part of a greater whole, encouraging them to improve their dynasty's reputation instead of merely being obsessed with personal status.
-10% Casus Belli Prestige Cost +50%"Fabricate Claim on County" Councilor Task Speed
Land is the most valuable reward we can bestow upon our subjects, but there is only so much that we directly own. However, if we were to grant them permission to start farming that unworked land over there... who would object? Even if conflict does result, we will clearly be in the right when we defend our subjects!
+5% Republican Vassal Tax Contribution Unlocks the Scutage Feudal Contract
Military service has always been expected of our subjects, but there are some who are unable or unwilling to provide it. By offering a way for them to meet their obligations with coin instead of steel, we can ensure that we get our dues from everyone.
Counties reach the maximum Existing Development penalty at 55 Development
The great cities of Rome, Byzantium, and Delhi have long stood out as relics of a great, unmatchable legacy. As our infrastructure and population grow, we finally have the means to develop new settlements which rival these ancient urban centers.

+15% Levy Reinforcement Rate Unlocks all High Medieval Era Military Buildings
While the keep serves as the heart of a castle, it is far from the only important building. Constructing buildings like the stables and armory in a protected bailey will ensure we can properly garrison and equip our levies no matter the circumstances.
Unlocks all High Medieval Era Fortification Buildings
Placed on the top of our battlements, these wooden constructions extend out above the base of our castle walls. They allow our defenders to fire arrows, drop stones, or pour boiling oil on attackers while remaining completely protected from enemy archers.
+5 Direct Vassal Opinion +20% Knight Effectiveness
By bestowing knighthoods upon our best fighters and paying them with land holdings instead of mere coin, we can give them the honor they deserve as well as secure their loyalty to us.
+4 Size of Men-at-Arms Regiments +1 Max number of Men-at-Arms Regiments
Those skilled in the horse and the lance will always be in demand, but are not always available. Keeping groups of men-at-arms on retainer will ensure that we do not lack experienced fighters when war inevitably breaks out.
Can recruit Trebuchets as Men-at-Arms
An engineering marvel, the counterweight trebuchet can hurl heavy projectiles at distances further than any siege engine that came before it.
The Levant is an unfamiliar place with poor terrain for cavalry charges. We should adapt to these lands and field cavalry which is better suited to fight in our new home.

Riders on our Celtic hobby horses are both fast and agile — perfect for scouting and raiding in rough terrain where enemy knights are loathe to go.
Can recruit Picchieri Men-At-Arms
Pikemen have always been strong defenders, but they have historically lacked in mobility and offense. Devising new formations to address this deficiency will improve our chances of victory in battle.
Can recruit Sarawit Men-At-Arms
The highlands where our ancestors settled requires a particular approach to agriculture. The building of terraced fields taught us to develop new military tactics, which are employed by our Serawit soldiers.
+10 Different Culture Opinion +10% Monthly Development Growth
Wars, raids, and persecution all over the world have driven many people from their homes. By welcoming these displaced souls to our lands regardless of their background we can develop a rich and prosperous society.

The lands to our east are sparsely inhabited, but rich in natural resources. Establishing an initiative to expand and establish homesteads there will lead to the growth and prosperity of our people.
Our realm has expanded to the point where even minor nobles cannot administer everything effectively. Appointing court officials and bureaucrats to handle the more mundane court tasks will ensure that the wheels of government continue turning smoothly.
-15% Building Construction Time Unlocks all Late Medieval Era Economic Buildings
A forgotten marvel of engineering, the Romans used tread-wheel cranes to great effect when building their empire, and so too shall we.
+10% Monthly Prestige
Anyone may claim a title, but in order to be a true monarch they must inspire awe and majesty in their subjects. Our new ermine cloaks are a form of regal dress which is sure to accomplish just that.
+5 Direct Vassal Opinion +5 Fellow Vassal Opinion
Nobility is more than just privileges and rights; it also comes with a duty to the realm, an obligation to act in ways that are proper and just. Clearly establishing what is expected from our elite will give us an ideal to aspire to and bring us together as we work to achieve it.
Can enact the Primogeniture Law Can enact the Ultimogeniture Law
One kingdom, one heir. While the younger children of our monarch may feel forsaken by being denied an inheritance, this is the best way to ensure we keep a stable realm which does not get torn apart by succession crises.

An evolution of earlier banking systems, paper promissory notes allow our citizens to quickly and safely trade goods and services across large distances without being weighed down by heavy specie.
Counties reach the maximum Existing Development penalty at 90 Development

It is our divine right to possess our de jure lands, and it is time the world recognizes this fact. No longer will we be held back by obsolete protocols and decorum.

Unlocks all Late Medieval Era Fortification Buildings
A notable improvement on our earlier hoardings, stone machicolations serve the same purpose while being significantly more durable and offering more protection for our defenders.

+15% Levy Reinforcement Rate Unlocks all Late Medieval Era Military Buildings
As the size of our armies increases, we must guarantee that each and every soldier will be properly armed and armored. The establishment of a royal armory to produce and house all of our armies' equipment will go a long way towards meeting this need.

+5 Size of Men-at-Arms Regiments +1 Max number of Men-at-Arms Regiments
Military levies provide us with large numbers of soldiers, yet no matter how well we try to train and equip them they will always be inferior to professional soldiers. Establishing a large standing army will ensure the interests of our realm are enforced by the best fighters around.
Weapons like the goedendag are cheap and easy to produce, yet surprisingly effective against cavalry charges. Their existence allows us to adapt our militias to have much better odds when fighting armored knights.
Can recruit Palatini Men-At-Arms
Just as we have restored the Roman empire, so too shall restore the structure of the old Roman legion and its feared elite troops!
Can recruit Longbowmen Men-At-Arms
Taking advantage of the strong yew wood that grows here, our bowyers have learned to make longbows so powerful they require specialized training from an early age to use effectively. This investment is worth it, as our longbowmen can shoot arrows which travel further and penetrate deeper than those fired by other archers.
Can recruit Schiltron Men-At-Arms
The traditional pike circle is a powerful defensive formation, but it is limited in offense and mobility. While requiring great discipline to employ, our rectilinear schiltron is a superior formation which is capable of both powerful offensive and defensive tactics.
Can recruit Gendarmes Men-At-Arms
Establishing a valet system of dedicated servants for our noble horsemen will enable us to field knights who are both better armed and armored.
All Central Germanic except Dutch and Frisian
Can recruit Landsknechts Men-At-Arms
These massive two-handed swords are as adept at cutting down charging knights as they are at breaking enemy pike formations, making them a formidable addition to our own pike regiments.
Being both wealthy and centrally located, Italy has become a major center for mercenary companies to travel to when not on active campaign. Since they are already here, we should be able to negotiate a better rates for them than they would normally charge.
+5 Same Faith Opinion
The influx of new beliefs and religions into our society has made it clear that our past focus on regionalism has been a mistake. We should band together with others of our faith and ensure a strong and enduring state that can stand up to external pressures.
