Good morning! As promised, the focus of todays dev diary is Vietnam.

In 1444 Dai Viet is a newly independent nation, having won its sovereignty in a bloody war against the occupying Ming Chinese forces through the efforts of Vietnamese national hero L Loi. Early campaigns against Champa began a centuries-spanning process of Vietnamese expansion southwards. Dai Viet is now ruled by L Lois infant grandson Bang Co, though true power resides with Queen Regent Nguyen Thi Anh and Trinh Kha (a 2/3/5/1 General). For all the promise of the early L dynasty, the seeds of its undoing were already present; the immense power that would be hoarded by the Nguyen, Trinh, and Mac families would divide the nation multiple times throughout our period.

Shown above is the new Vietnamese mission tree available to Dai Viet, Annam, and Tonkin. Some highlights:

• Like other nations in this update, Dai Viet receives many Subjugation CBs through its mission rewards. Dai Viet gets Subjugation CBs on Lan Xang, Lan Na, Khmer, and Ayutthaya. They later get permanent claims on Burma.
  
• The rightmost mission branch begins with the Rule Muang Phuan mission. Muang Phuan is a small semi-independent nation in the strange position of being guaranteed by both Lan Xang and Dai Viet, while also being a tributary of Ming. You can either try to diplomatically vassalize Muang Phuan or ignite the powder keg of war with Lan Xang by launching an invasion.
  
• The Defy Ming mission can allow you to steal the Ming subject Yue during their Crisis Disaster, so it may be worthwhile to time completion opportunistically. The mission also reduces Mings Mandate by 20, so again it pays to be opportunistic and complete the mission when youre ready to engage them on the battlefield.
  
• Completing the Claim the Mandate mission fires an event that allows you to cosmetically change your nations name. You can choose between Viet Nam, Dai Nam, or stick with Dai Viet.
  
• The Purchase Western Arms mission requires having strong relations with a European power present in the East Indies, and rewards a permanent -30% Artillery Cost and +10% Siege Ability.
  
• The Faith and Learning mission requires constructing many Temples and achieving high religious unity. If you are playing a Confucian nation this rewards a large permanent bonus to your Harmonization Speed, else it permanently reduces your Idea Cost by 5%.
  
• The State Education mission requires the construction of Universities, and adds Institution progress to your capital for each Institution that is active but not yet fully present in the capital.
  
• The Imperial Citadel mission does something I cant talk about yet, but also gives you the opportunity to move your capital to Hue, or else rename Dong Kinh to Hanoi.
  

• Dai Viet begins with a new generic Estate Privilege for the Nobility called Control of the Army. This privilege greatly increases Nobility influence, increases Leader Cost, adds additional Nobility influence whenever you recruit a leader, and adds a little monthly Army Tradition (its not all bad). The Control the Army mission requires you to revoke this privilege while building to 100% of your land force limit.
  
• The Curtail the Nobility mission requires reducing the influence of the Nobility estate while holding at least 50% Crown Land.
  
• The Restore Examinations mission refers to the Confucian examination system employed by China, Vietnam, and Korea throughout various points of their respective histories. State officials must complete a series of examinations that test their knowledge of Confucian literature and statecraft before they can assume office, a system that was at least theoretically meritocratic as the examinations were open to all. You must enact The Examination System government reform (shown below) while also employing any 3 advisors without running a deficit.
  
• Prevent Division simply requires you to own Dai Viets core territories, have 2 stability, and for neither Tonkin nor Annam to exist. Completing this mission prevents the Northern and Southern Dynasties disaster from ever happening, and rewards -10% Stability Cost Modifier for the rest of the game.
  

• The Reconquer Indrapura mission tasks you with reconquering the two provinces to your north. On completion both provinces become Cham culture, and Shunhua is renamed to Kandarapura.
  
• Completing the Conquer Vietnam mission rewards -20% Culture Conversion Cost for the rest of the game.
  
• Completing Subjugate the Highlands grants a Subjugation CB against the weakened Khmer Empire.
  
• The Malay Connections mission requires that you have a moderately powerful Sunni ally in the Malaya region, such as Malacca. On completion you are offered an opportunity to convert to the Sunni faith.
  
• The Expedition to Tondo mission requires conquering parts of Luzon and having a Colonist from any source. It grants +25% Colonial Range for the rest of the game, encouraging an early exploration of the Americas.
