Other Education Research

These are all the other branches of the education research tree. These branch off from the essential research parts of the education research tree.


Architecture

Level 1 Increase build speed of village buildings: 20%
Level 2 Increase build speed of village buildings: 40%
Level 3 Increase build speed of village buildings: 60%
Level 4 Increase build speed of village buildings: 80%
Level 5 Increase build speed of village buildings: 100%
Level 6 Increase build speed of village buildings: 120%
Level 7 Increase build speed of village buildings: 140%
Level 8 Increase build speed of village buildings: 160%
Level 9 Increase build speed of village buildings: 180%
Level 10 Increase build speed of village buildings: 200%

After you have placed a few buildings in your village near the start of the game you will notice that the build time of your buildings rises very high. Researching construction will knock a very large chunk of the build time of new buildings and allow you to build new buildings relatively quickly again. It’s worth researching this up full but only when you have sufficient production to allow you to place new buildings.


Merchant Guilds

Level 1 Access to merchants and trading in parish
Level 2 Merchants per market: 2
Level 3 Merchants per market: 3
Level 4 Merchants per market: 4
Level 5 Merchants per market: 5

One of the very first things you should do in stronghold kingdoms is giving yourself access to trading. It gives you the ability to buy resources you don’t have and sell the excess of what you do have to generate gold. Trading plays a major role in the game. Each level you research up merchant guilds allows you an extra trader at every market. Early in the game you should place between 6 and 10 markets allowing you between 30 and 50 traders which will give you the ability to produce massive amounts of gold from trading.


Transportation

Level 1 Increase merchant speed: 50%
Level 2 Increase merchant speed: 100%
Level 3 Increase merchant speed: 150%
Level 4 Increase merchant speed: 200%
Level 5 Increase merchant speed: 250%
Level 6 Increase merchant speed: 300%
Level 7 Increase merchant speed: 350%
Level 8 Increase merchant speed: 400%
Level 9 Increase merchant speed: 450%
Level 10 Increase merchant speed: 500%

Transportation research goes hand in hand with merchant guilds. Traders move painfully slow at the beginning when you first unlock them. This research increases their speed by a huge amount once it is full, allowing you to trade very quickly, even with places relatively far away.


Commerce

Level 1 Trade within your same county
Level 2 Trade within your same province
Level 3 Trade within your same country
Level 4 Trade worldwide

Commerce research allows you to trade with different areas. At the first level it allows you to trade within the county your village is in. After that it allows you to trade within the province your village is in, then the country and finally the last level allows you to trade worldwide. In my opinion you only need to get this to level 2 or 3. Trading with foreign countries isn’t strictly necessary. There are enough markets with your province or in your own country to ensure you gain the best price when trading.


Stockpile Capacity

Level 1 Increase stockpile capacity: 30%
Level 2 Increase stockpile capacity: 50%
Level 3 Increase stockpile capacity: 75%
Level 4 Increase stockpile capacity: 100%
Level 5 Increase stockpile capacity: 150%
Level 6 Increase stockpile capacity: 200%
Level 7 Increase stockpile capacity: 300%
Level 8 Increase stockpile capacity: 400%
Level 9 Increase stockpile capacity: 600%
Level 10 Increase stockpile capacity: 800%

This research effects your lumber, stone, iron and pitch capacities. Because every time you build a building the cost increase, you need to expand your stockpile capacity early in the game. The stockpile at the start of the game is very small and its limit will allows you to place essential buildings to generate resources but as for things like a large weapon production capability, you need to expand the stockpile very high because buildings for creating weapons cost a lot. The same goes for the religious buildings; they take tens of thousands of each resource to place. Try to research the stockpile to the maximum as soon as possible so you can let large amounts of resources build up and ensure you have the necessary capacity to place any building you want.


Granary Capacity

Level 1 Increase granary capacity: 30%
Level 2 Increase granary capacity: 50%
Level 3 Increase granary capacity: 75%
Level 4 Increase granary capacity: 100%
Level 5 Increase granary capacity: 150%
Level 6 Increase granary capacity: 200%
Level 7 Increase granary capacity: 300%
Level 8 Increase granary capacity: 400%
Level 9 Increase granary capacity: 600%
Level 10 Increase granary capacity: 800%

Increasing your food capacity means you can let it pile up over time and run very high rations for a long period early in the game. Also you can sell it and make a lot of gold.


Hall Capacity

Level 1 Increase hall capacity: 30%
Level 2 Increase hall capacity: 50%
Level 3 Increase hall capacity: 75%
Level 4 Increase hall capacity: 100%
Level 5 Increase hall capacity: 150%
Level 6 Increase hall capacity: 200%
Level 7 Increase hall capacity: 300%
Level 8 Increase hall capacity: 400%
Level 9 Increase hall capacity: 600%
Level 10 Increase hall capacity: 800%

If you want to banquet a lot early in the game try to research up your hall capacity bit. Because your capacity is very small at the start of the game, if you scout lot of honour good resource stashes you can end up losing lot if you fill your capacity and the excess gets wasted.


Inn Capacity

Level 1 Increase inn capacity: 30%
Level 2 Increase inn capacity: 50%
Level 3 Increase inn capacity: 75%
Level 4 Increase inn capacity: 100%
Level 5 Increase inn capacity: 150%
Level 6 Increase inn capacity: 200%
Level 7 Increase inn capacity: 300%
Level 8 Increase inn capacity: 400%
Level 9 Increase inn capacity: 600%
Level 10 Increase inn capacity: 800%

It’s actually not necessary to research up your inn capacity at all. You can just set your ale rations to maximum and whatever production of ale you have it will automatically adjust your rations. What this means is you can just need to produce enough ale to run decent rations all the time and don’t bother selling any.


Armoury Capacity

Level 1 Increase armoury capacity: 50%
Level 2 Increase armoury capacity: 100%
Level 3 Increase armoury capacity: 200%
Level 4 Increase armoury capacity: 400%
Level 5 Increase armoury capacity: 600%
Level 6 Increase armoury capacity: 800%
Level 7 Increase armoury capacity: 1000%
Level 8 Increase armoury capacity: 1300%
Level 9 Increase armoury capacity: 1600%
Level 10 Increase armoury capacity: 1900%

Armoury capacity is something that you need to research up high fairly early so you can build up large amounts of weapons when you are offline that will allow you to build large armies and also donate to the parish capitals most important buildings. The biggest bonuses here are at the highest levels so if possible complete all the armoury research so you can store 600 of each type of weapon.


Housing Capacity

Level 1 Increase hovel capacity by 1
Level 2 Increase hovel capacity by 2
Level 3 Increase hovel capacity by 3
Level 4 Increase hovel capacity by 4
Level 5 Increase hovel capacity by 5
Level 6 Increase hovel capacity by 6
Level 7 Increase hovel capacity by 7
Level 8 Increase hovel capacity by 8

Having a high population gives you many benefits. You can have very high tax and make a lot of gold; however you need more food for a bigger population. Its other main benefit is that you can have a lot bigger idle population to use for training troops.


Literature

Level 1 Gives access to Theatres
Level 2 Gives access to Jester Courts
Level 3 Gives access to Dancing Bears
Level 4 Gives access to Troubadours Arbors
Level 5 Gives access to Maypoles

Literature is one of the most important researches at the very start of the game as it allows you to place the entertainment buildings which give you a big boost to your popularity and allow you to gain honour to rank up quickly.


Decoration

Level 1 Gives access to Flower Beds
Level 2 Gives access to Dovecots
Level 3 Gives access to Stone Statues
Level 4 Gives access to Formal Gardens
Level 5 Gives access to Gilded Statues

Decoration is another research that is very important early in the game if you want to rank up very fast. Every piece of decoration placed increases your honour multiplier and the buildings unlocked at the higher levels of this research give a massive boost to your honour multiplier.


Ordination

Level 1 Maximum monks: 1
Level 2 Maximum monks: 2
Level 3 Maximum monks: 3
Level 4 Maximum monks: 4
Level 5 Maximum monks: 5
Level 6 Maximum monks: 6
Level 7 Maximum monks: 7
Level 8 Maximum monks: 8

Ordination allows you to train monks which in turn allow you to stat researching their abilities. Each level you research this up unlocks 1 more monk up to a maximum of 8.


Pilgrimage

Level 1 Increase monk speed: 25%
Level 2 Increase monk speed: 50%
Level 3 Increase monk speed: 75%
Level 4 Increase monk speed: 100%
Level 5 Increase monk speed: 125%
Level 6 Increase monk speed: 200%
Level 7 Increase monk speed: 350%
Level 8 Increase monk speed: 500%

When you first unlock monks they move very slowly. By researching pilgrimage up full you can increase their speed by 500%. You really need to get this research full if you are sending monks over long distances, otherwise it can take hours or even days to reach your target. Also if you are doing some of the monk related quests like using inquisition or curing disease you really want to have this full first so you can complete them as fast as possible.


Baptism

Level 1 Remove disease from parish: 3
Level 2 Remove disease from parish: 4
Level 3 Remove disease from parish: 5
Level 4 Remove disease from parish: 6
Level 5 Remove disease from parish: 7
Level 6 Remove disease from parish: 8
Level 7 Remove disease from parish: 9
Level 8 Remove disease from parish: 10

Baptism is not a hugely important thing to research early on. It can help you to research this if you are doing the cue disease quests, but otherwise if you cure disease early in your parishes before it gets too high you really don’t need your monks to be able to cure large amounts of disease each.


Marriage

Level 1 Parish blessing time: 6 hours
Level 2 Parish blessing time: 9 hours
Level 3 Parish blessing time: 12 hours
Level 4 Parish blessing time: 16 hours
Level 5 Parish blessing time: 20 hours
Level 6 Parish blessing time: 24 hours
Level 7 Parish blessing time: 30 hours
Level 8 Parish blessing time: 36 hours

Blessing is another research that you can leave until you have everything else important finished. It just costs too many faith points to bless your parishes all the time even if you research this full.

Confirmation

Level 1 Decrease parish popularity time: 4 hours
Level 2 Decrease parish popularity time: 6 hours
Level 3 Decrease parish popularity time: 8 hours
Level 4 Decrease parish popularity time: 10 hours
Level 5 Decrease parish popularity time: 12 hours
Level 6 Decrease parish popularity time: 16 hours
Level 7 Decrease parish popularity time: 20 hours
Level 8 Decrease parish popularity time: 24 hours

Inquisition is a research you can completely avoid researching past level 1. The reason being if you want to do the inquisition quests very fast the best way is usually to inquisition your own parishes because they will usually be the closest to your villages. This means if you have this researched up high it will be detrimental to yourself.


Eucharist

Level 1 Prevent attacks on villages: Rank 8
Level 2 Prevent attacks on villages: Rank 12
Level 3 Prevent attacks on villages: Rank 15
Level 4 Prevent attacks on villages: Rank 17
Level 5 Prevent attacks on villages: Rank 19
Level 6 Prevent attacks on villages: Rank 20
Level 7 Prevent attacks on villages: Rank 21
Level 8 Prevent attacks on villages: Rank 23

Interdiction is probably the most important monk ability in the game as it allows you to interdict yourself or your allies so you can’t be attacked by human players or AI castles and siege camps. As long as you research this up 1 level you can interdict yourself no matter what rank you are. The rest of the levels you research it up allies to other players you want to interdict.


Confession

Level 1 Reduce time of excommunicated village: 1 hour
Level 2 Reduce time of excommunicated village: 2 hours
Level 3 Reduce time of excommunicated village: 3 hours
Level 4 Reduce time of excommunicated village: 4 hours
Level 5 Reduce time of excommunicated village: 6 hours
Level 6 Reduce time of excommunicated village: 8 hours
Level 7 Reduce time of excommunicated village: 10 hours
Level 8 Reduce time of excommunicated village: 12 hours

Confession allows you to counteract the monk ability excommunication and allows villages to use their monks again. This is a very important research as you can remove excommunication for a very small number of faith points compared to what the other person has spent excommunicating you or you allies.


Extreme Unction

Level 1 Remove church powers: 1 hour
Level 2 Remove church powers: 2 hours
Level 3 Remove church powers: 3 hours
Level 4 Remove church powers: 4 hours
Level 5 Remove church powers: 6 hours
Level 6 Remove church powers: 8 hours
Level 7 Remove church powers: 10 hours
Level 8 Remove church powers: 12 hours

Extreme unction gives you access to the monk ability excommunication which allows you to send monks to excommunicate villages and remove their ability to use monks for a certain period of time. This can be very helpful to you as it means the other player cannot interdict themselves or send monks to excommunicate you.


Philosophy

Level 1 Reduce research point gold cost: 5%
Level 2 Reduce research point gold cost: 10%
Level 3 Reduce research point gold cost: 15%
Level 4 Reduce research point gold cost: 20%
Level 5 Reduce research point gold cost: 25%
Level 6 Reduce research point gold cost: 30%
Level 7 Reduce research point gold cost: 35%
Level 8 Reduce research point gold cost: 40%
Level 9 Reduce research point gold cost: 45%
Level 10 Reduce research point gold cost: 50%

When you rank up through the early ranks you will find that you build up a large surplus of research points especially if you gain a lot of honour every day and rank up very fast. When you reach prince, if don’t build the 5 extra villages you can at prince, and just rank up through all the sub ranks and reach crown prince you can build up dozens of research points. If you do this when you are down to your last 10 start researching up philosophy. You don’t get any research points for ranking up through crown prince degrees which means the last ranks at which you can acquire them is prince so after this you will have to start buying them so its best when you are down to your last 10 research points to max philosophy so you can buy research points as cheaply as possible.


Justice

Level 1 Allows access to stocks
Level 2 Allows access to burning posts
Level 3 Allows access to stretching racks
Level 4 Allows access to Gibblets

Justice allows you to place buildings which provide a fairly large boost to your honour multiplier but bring down your popularity. In my opinion just place the last 2 buildings, the stretching racks and Gibblets as they provide the biggest boost and they won’t bring down your popularity too greatly.
