Rival Haixi, Udege, Donghai
Ally Korchin, if they become a Ming tributary
Declare on Haixi when new cavalry regiments are at least half strength
Occupy all Haixi provinces fast and full annex
Attack Udege next and take all provinces with Jurchen culture
Attack other tribes when possible to get to 20 cored Jurchen culture provinces
Form Manchu
Manchu-
Raise more banners and reconquest rest of the northern tribes
Dissolve alliance with Korchin
Attack Korea and take couple of provinces and humiliate
Keep an eye on the mission tree and complete missions when possible
Attack Korchin after truce is up and full annex them
You should have claims or cores on everyone you have conquered till now
Once your total development is 300+ cancel tributary to Ming
Try to ally Oirat when possible
Rival Ming if possible and declare war with mandate of heaven CB calling in Oirat either with promise of land or with favors
Play slow and keep your armies together
Siege down Shenyang and Beijing
Wait for unguarded frontier disaster to fire then peace Ming with your cores and provinces you need to complete the next mission along with all their money and war reparations
Attack Korea again if possible and take some provinces and more money
Then attack Mongolia as you need provinces from them to form Qing
Once Ming truce is over, declare again and this time take the mandate along with money and war reparations
Now you can form Qing
Qing-
Keep expanding in China and pay attention to managing mandate
Next priority is to get more tributaries
Also prioritize the provinces of Nanjing and Canton
You have claims on all of China and with unify China CB you can take a lot of provinces very quickly
Declare on every breakaway chinese nation as soon as you border them
For expanding west, you should declare war to take some provinces and get borders with more nations. Then declare war again and make them a tributary.
Ideas
Colonizer Qing-
Exploration-
possible to spawn colonialism
Put down colonies in Indonesia and Philippines. Make tributaries.
Abandon colonies. Rinse and repeat.
With golden century, you can also expel minorities to get more Manchu culture and thus more banners.
2. Expansion
3. Military idea
Expansionist Qing-
Administrative
-45% coring cost reduction
Just take first two ideas and then finish up the idea group later when you have spare admin points
2. Defensive-
Chinese tech units are not the strongest so it helps to have some extra morale.
Attrition is terrible in mainland China so defensive helps there as well.
3. Exploration
After that you can either focus on colonization or fast expand into Indochina and Burma regions going towards India as well as expanding west towards Russia.
